THE BEST WHEELSET FOR THE MONEY – PART 2

Summary:  Value-carbon wheels that some call the “best wheelset for the money” sell for between US$900/£750/€900 to $1500/£1300/€1500. While a few have particular strengths, none match the range and level of performance of wheelsets that cost nearly twice as much. Some also come with very limited warranties.

The best value-carbon wheels I’ve found are the Zipp 303 S for cyclists committed to riding tubeless tires and available here for North American residents and here and here for those in Europe from stores I recommend for their competitive prices and customer satisfaction ratings, and the Bontrager Pro 37 for those who prefer to ride tubed clincher tires and available here and here. You can read my reviews of them starting here


What is the best wheelset for the money? Should I consider Chinese carbon wheels from Yoeleo, Farsports, Light Bicycle, and others? What should I expect of relatively inexpensive bicycle wheels that are only sold online from brands like Prime wheels, FLO Cycling, or Hunt wheels? What about those wheelsets from Profile Design or Rolf Prima that are available primarily through US retailers?

How do these compare to more expensive carbon wheelsets and the lower-priced carbon models widely available from the long-established, better-known wheel makers like Zipp, Bontrager, Reynolds, and Fulcrum?

That’s how I opened Part 1 of my Best Wheelset for the Money. In that post, I laid out a way to compare the companies making all-around carbon wheelsets selling in the US$900/£750/€900 to $1500/£1300/€1500 price range. I provided you, my fellow road cycling enthusiast on a tight budget yet still wanting carbon wheels, perspective on how those companies approach engineering, production, sales, and service differently.

The post also included info about how long these companies have been selling carbon wheels, how much each company appears to be involved in the design and manufacturing of the carbon wheelsets they sell, what return, crash replacement, and warranty policies they offer, and what the price and design specs are for their <$1500 all-around wheelsets.

All of this was intended to help you learn more about the companies whose wheelsets you might consider buying beyond the relatively low price of their carbon wheels. I certainly have, and I imagine you all have some basic requirements that must be met before spending a good chunk of change on cycling gear from any company. Hopefully, the added knowledge about these companies, some of which you may have known little or nothing about before, will help you in your decision-making.

What I didn’t do in that first post was share with you my on-the-road performance evaluations of these value-carbon wheels. Once I’m good with the company behind a wheelset and the price being in my budget range, performance matters most.

First, I’ll share my experience on how the performance of value-carbon wheels differs from that of full-priced performance-carbon wheels and lower-priced alloy upgrade wheels. Then, I’ll first summarize how the companies selling value-carbon wheels approach the business in different ways, the focus of what I laid out in Part 1.

Finally, I’ll give you my performance reviews for those value-carbon wheelsets we have completed testing.

PERFORMANCE DIFFERS BETWEEN VALUE-CARBON AND OTHER CARBON AND ALLOY WHEELS 

I’ve frequently heard some riders say value-carbon wheels, those that sell in the US$900/£750/€900 to $1500/£1300/€1500 price range get you 80%-90% of the performance at 1/2 to 1/3 of the price of full-priced or what I’ll call “performance-carbon wheels”.

While that is a memorable line, it lacks the context to make it useful, let alone accurate.

It’s really hard to make any overarching statement like that without knowing, for example:

  • Which value-carbon wheels and which performance-carbon wheels are you comparing?
  • Which performance characteristics are you considering?
  • Which characteristics are most important to you in making a wheelset decision?

As you likely know and can see on the home page, I and my fellow In The Know Cycling testers review and compare a half-dozen or more wheelsets from an entire category that are intended for a similar purpose and put it into a single post for you. Which are the best climbing or all-around or aero wheelsets? Which are the best alloy upgrade wheelsets? Which are the best wheelsets in each of those categories for rim brake bikes vs. disc brake bikes? And how do you choose between those categories to find the best for you?

While there are performance characteristics that are unique to each category or more important when comparing wheels in some categories versus others, there are a handful of characteristics that are important across all categories.

Most of the value-carbon wheels I am reviewing in search of “the best wheelset for the money” are all-around category wheels. This category includes mid-depth (40-50mm) wheelsets that are intended to be used for training and road racing, on the flats and in the climbs, mostly on the road but also for a modest amount of cross or dirt riding off of it as well.

As the “all-around” description suggests, these wheels are good in most situations if not ideally suited for one specific terrain (e.g. climbing), event (e.g. time trials), or surface (e.g. smooth, paved roads).

The performance criteria I and my fellow testers use in evaluating wheelsets in this category, and most other categories to a greater or lesser degree, are versatility, specificity, aero drag, sidewind stability, lateral stiffness, vertical compliance (aka comfort), responsiveness, durability, and for rim brake wheels, braking. You can read more about what I mean by each of these on my wheelset selection criteria page.

In this section, I’ve compared some of the better and average value-carbon wheels against some of the better and average performance-carbon wheels and alloy upgrade wheels made for rim brake and disc brake road bikes using these same criteria.

This is a fool’s errand but I’m a fool and am trying to provide you a general reference point of what to expect for a specific performance characteristic between wheelsets we’ve tested representative of these three different groups. This will hopefully be better than the horribly inexact and simplistic “x% of the performance at y% of the price” statement I mentioned at the top of this section that some people lean on.

I’ve no doubt that I will get comments from some saying my $500 alloy wheelset far outperforms the $3000 carbon wheelset those I race against or ride with use in this or that situation. I won’t try to confirm or explain why your experience or evaluation differs from mine.

My fellow testers and I have ridden, compared, and reviewed many, many wheelsets. You can read and compare my take on whatever wheelsets you are interested in by entering the wheelset name in the “Find a review…” box at the top of the page.

Rather, what follows is a distillation of our experience.

Versatility

(Comparative Performance Key: + Better, 0 Par, – Worse)

The most desirable all-around wheels will provide the versatility to ride different types of terrain (hills, flats, false flats, straights, corners, sprints, mountains, fast downhills, windy roads) that you’ll experience and a range of training and many events (club races, centuries, club, charity, group rides) you’ll do without compromise.

With the growing popularity of cyclocross and gravel or dirt riding, you can add a wheelset’s ability to ride road and these off-road situations to the versatility consideration.

Performance-carbon wheelsets clearly have an advantage here. The better and many of the average rim and disc wheelsets are more aero, responsive and comfortable, and climb better than value-carbon or alloy upgrade wheels we’ve ridden. That makes them more versatile for the range of terrain you might ride, events you might do, and surfaces you might traverse, especially if you are comparing the more modern disc brake wheelsets.

The better and average value-carbon wheels I’ve tested are somewhat more versatile than the better and average alloy upgrade wheels. Being deeper and with good hubs, they are better at holding aero speeds above 20mph/32kph. In quite a few cases, however, that comes with crosswind management issues that you don’t experience with the shallow alloy upgrade wheels (or the more advanced rim profile designs of the performance-carbon all-around depth wheels).

While most of the value-carbon wheels are wider than most of the alloy upgrade wheels, I haven’t found the former group to be any more comfortable. This limits your desire to want to ride them off-road (and in some cases on it).

To fill out the versatility consideration, I think about how much I’d like to climb with these wheels. The value-carbon wheels are generally a bit heavier than the performance-carbon ones. Others are not as stiff. I haven’t found any that are as light and stiff as the better and average performance-carbon wheelsets.

Alloy upgrade wheelsets, though shallower than value-carbon ones, aren’t noticeably lighter and often not as stiff. This limits their versatility.

Specificity

(Comparative Performance Key: + Better, 0 Par, – Worse)

With less engineering put into value-carbon wheels than performance-carbon ones and almost none going toward new alloy-upgrade ones, it’s unlikely that you’ll find terrain, surface, or discipline-specific wheelsets that perform at the same level as performance-carbon ones outside of those from that category.

Value-carbon wheels often have some combination of older rim profiles, lower speced carbon layups, or less advanced hubs. From a performance sense, this makes them less aero for flats and speed disciplines and heavier for climbing and many road racing ones than performance-carbon wheels. They’ll also usually not have as wide to enhance comfort or as stable in side winds.

Modern alloy wheels, for the most part, aren’t designed for specific terrain, surfaces, or events. The limitations with shaping the rims and the added weight that comes with a wider or deeper rim removes them from the ability to compete on specificity.

Aerodynamic Drag and Sidewind Stability

(Comparative Performance Key: + Better, 0 Par, – Worse)

With few exceptions, this is quite clear-cut and for understandable reasons. The better and even average performance-carbon wheelsets tend to have more engineering invested in developing rims that are more aero and stable in the normal 0 to 10-degree yaw angles and 10mph+ side winds than value-carbon ones.

Depending on the company’s strategy and business activities (see Part 1), value-carbon wheels generally come with rims designs used in earlier generation performance-carbon wheels made by the company or are older designs from companies that just can’t afford to invest in updating the rims as often as those in performance-carbon wheelsets or are copies of generation or two-old performance-carbon rims.

Alloy upgrade wheels are typically in the 25mm +/- rim depth. This makes them about 20mm shallower than the value-carbon and performance-carbon wheelsets. At aero speeds, you will notice a difference. On the flip side, many of the value-carbon wheels with their older designs require a good deal of side wind management whereas the shallower wheels generally don’t.

No, I don’t test wheels in the In The Know Cycling wind tunnel. (There isn’t such a thing.) Instead, my observations are anecdotal and based on riding a lot of wheelsets at different aero speeds and wind conditions over time and doing back-to-back rides in similar conditions. The more aero wheels maintain their momentum at aero speeds better than less aero ones.

Lateral Stiffness

(Comparative Performance Key: + Better, 0 Par, – Worse)

Stiffness is a performance characteristic that is specific to a wheelset. Some are stiffer than others regardless of the category of wheels they might fall into. There are plenty of stiff wheels that transfer your power efficiently within each category and at each price point.

You can see which wheelsets are stiffer in the charts that summarize and compare performance within each category review.

Vertical Compliance (aka Comfort)

(Comparative Performance Key: + Better, 0 Par, – Worse)

Comfort is relative and very much in the eye of the beholder or should I say hands and rear end or the biker. We used to ride around on 15C wide alloy wheels pumped up to 120 psi with nary a complaint about comfort.

Now, the focus on comfort seems to be a sub-industry unto itself with some tires and wheels sold on the premise that their width will provide you comfort.

A few things to point out first. Comfort is an outcome of a wheelset’s vertical compliance, what tires you use, and how much you inflate them. You can make a wheel more or less comfortable by running it tubeless, using better tires, and lowering the pressure.

But, you can only do so much to make a wheelset comfortable given its compliance. Vertical compliance is determined by the wheel’s rim, spoke, and hub materials and how they are aligned and assembled.

All the marketing around a wider rim making for a more comfortable ride is misleading. If everything I’ve written about above is the same between two wheels, then yes, a wider rim on a wheelset could be more comfortable. But, all else is never the same between wheels from two different companies and there’s often enough difference that width isn’t the dominant factor in determining comfort.

Indeed, I found a 16mm wide (internal) value-carbon wheelset with 23C tubed tires inflated at 75 psi to be clearly more comfortable than a 21mm wide (internal) value-carbon wheelset with 25C tubeless tires inflated at 60 psi ridden on the same roads.

While it is unusual to find that situation, it illustrates the point that wheelset width does not predict comfort. Vertical compliance along with tire choice and inflation pressure does and there’s no way to predict compliance from specs. I set up our performance-carbon and value-carbon wheels tubeless using the same brand, model, and size tires and at the same pressures. I was also able to spec most of the value-carbon wheelsets we tested with DT Swiss 240 hubs, a top-performing hub used on the best wheelsets in all three groups.

Some 19C wheelsets will be more comfortable than some 21C wheelsets. One 19C wheelset will be comfortable, another will be passable while a third will be harsh. It’s just not about the rim width.

For those of you focused on tire width, know also that aero performance, handling and comfort are interdependent. You just can’t put on a set of 28C tires to improve comfort without potentially affecting your aero performance and handling. I wrote this post about that subject. And, one brand’s 25C tire can be a millimeter wider than a 25C tire from another brand, and both are almost never going to be as narrow as 25mm once mounted and inflated on even a 17C wheel.

So what about the vertical compliance of the three different groups of wheelsets?

Like stiffness, a lateral measure that is also dependent on the wheel’s rim, spokes, and hub materials and how they are aligned and assembled, vertical compliance is unique to a wheelset.

That said, I’ve found the better and average performance-carbon wheels as a group of individual wheelsets to be more comfortable than either better and average value-carbon or alloy upgrade wheels.

I’m not sure why this is but I’ll guess it’s simply a result of money. More engineering goes into performance-carbon wheels than either of the other types. Companies are hip to the reality that we cyclists want comfort today so the companies making performance-carbon wheels spend the money to engineer their wheels to be more compliant. The others either can’t afford to or don’t choose to.

Responsiveness

(Comparative Performance Key: + Better, 0 Par, – Worse)

Responsiveness is a measure of how quickly a wheelset accelerates from a stop or when you attempt to accelerate while underway from one speed to a much faster one. You accelerate most often after slowing at a stoplight or sign or after making a turn. If you race or group ride, you might accelerate to start a breakaway, move past someone slowing in front of you, kick it in on a hill, or when doing a sprint for the town line or finish line.

I’ve found that performance-carbon wheels are some of the most responsive around. This certainly isn’t the case with all performance-carbon wheels, but I’ve seldom found value-carbon or alloy upgrade wheels to be as responsive.

You might wonder, if stiffness is wheelset specific why wouldn’t responsiveness be as well? It’s hard to pinpoint exactly why for a given wheelset but some combination of stiffness, aerodynamics, weight, carbon layup, hub engagement, spoke placement, and perhaps other factors will determine how responsive a wheel is when you try to accelerate. Performance-carbon wheels can give you some combination of more aero, lighter, using higher-grade carbon or better hubs than either value-carbon or alloy upgrade wheels.

Value-carbon wheels are usually more aero but heavier than alloy upgrade ones. This might explain why I’ve found little difference in their responsiveness.

Braking

(Comparative Performance Key: + Better, 0 Par, – Worse)

This criterion, of course, relates only to rim brake wheels. For disc brake wheels, braking performance is determined by the brakes and rotors rather than the wheels, assuming the hubs and spoke bracing are structurally up to the job.

When evaluating a rim brake wheelset’s braking, I consider how much force is needed to slow or stop your wheels and how well you can modulate that force to control the rate of your deceleration as the two primary measures of braking quality.

If you use a good set of brake levers and calipers, well-maintained cables, the appropriate brake pads for the wheels, and properly aligned, spaced, and adjusted calipers, then differences in braking performance are going to be all about the difference in the brake tracks.

I recognize that’s a big if so if you are unsure whether your brakes are set up right, check out this video for a little home-wrenching advice.

Wheels with alloy brake tracks still perform the best in dry and wet road conditions. The better and even average performance-carbon wheels are damn close in dry conditions and the better ones are not far off alloy upgrade wheels on wet roads.

The current generation of performance-carbon wheels has closed the braking performance gap by texturing or treating their carbon brake tracks to increase the friction during braking, using improved resins to raise the temperature at which brake tracks heat up and fade or worse kicks in, and by advancing the manufacturing techniques in their rim lay-up process.

Unfortunately, most value-carbon rim brake wheels perform more like earlier generation carbon wheels. While some use higher temperature resins, I’ve not seen any with textured or treated tracks. Manufacturing techniques vary. The force isn’t there to slow the wheels nearly as much as textured or treated tracks and you’ll experience squealing and/or fading as the tracks heat up from repeated braking.

Those from companies with several generations of experience making carbon wheels shouldn’t warp and delaminate if you don’t drag your brakes (apply them 10-15 seconds or longer) and if you do use carbon braking techniques (alternate front and back wheels, brake no longer than 5 seconds at a time, brake hard initially on wet roads to squeeze out the water).

HOW COMPANIES SELLING VALUE-CARBON WHEELS DO BUSINESS  

There are two dimensions along which I organize the companies selling “the best wheelset for the money” or what I’m calling value-carbon wheels that sell in the US$900/£750/€900 to $1500/£1300/€1500 price range.

SCOPE – By scope, I’m referring to the range of business activities and operations, number and range of products, breadth of the cycling market segments served, or countries and geographies the companies sell to. Those selling value-carbon wheels either have a broad or focused scope.

SALES – Companies today are selling wheels (and most cycling products) through dealers, either online or at shops that represent them, or directly to cyclists from their own company websites.

Companies combine their scope and sales approach to follow one of four primary strategies shown in the chart below. You can read about each of these strategies in more detail here.

Value Carbon Wheelset Company Strategies

Within those strategies, companies either conduct or have other companies conduct for them a set of business activities shown in the chart below and described in more detail here.

Primary Wheelset Business Activities

A wheelset’s price is determined in part by how comprehensive or limited these business activities are. The price is also determined by how much margin companies need to put on top of the operating and investment costs of those activities and others supporting them to make an acceptable return and stay competitive in the market.

You can often find a lower-priced wheelset if you put a lesser value on some of these activities. Some of the companies selling value-carbon wheels spend less on those activities than others either by doing them more efficiently, by narrowing the scope of what goes into them, or by contracting some of those activities out to lower-cost sources.

For example, if you don’t put a lot of value into the research or testing that goes into some bike wheels, you can typically find lower priced ones from companies that don’t spend a lot on those activities and select the rim, hub, and spoke choices offered by those that have. On the other hand, if you want a set of wheels with a brand name the company has spent money to build through design, marketing, and service, you will likely pay more.

Do you care who or where the wheelset is made, how long it takes to get, how well it is made, or how long the warranty is? All those preferences have costs or cost savings associated with them.

The conventional thinking is that price differences are primarily guided by whether companies sell wheels and other cycling products through their distributors or direct to consumers. The reality is that the price differences between value-carbon wheelsets (and value-carbon and more expensive wheelsets) come because companies make a wide range of choices about how they run their business.

REVIEWS OF VALUE-CARBON WHEELSETS 

1. Integrateds 

Integrateds themselves do the activities or actively manage what others do integral to designing, producing, selling, and servicing wheels. They all use distributors and sell principally through online or shop dealers though some also sell direct from their company stores.

Since the Integrateds build wheels in advance and their distributors buy and stock the wheels for their dealers, you can usually order and get value-carbon wheels from them immediately or within days, the time it takes the order to ship to you from an online store or from a dealer to a local bike shop.

All the Integrateds sell more expensive performance-carbon wheelsets, certainly a greater range and most likely a larger number than the value-carbon wheelsets they sell.

These companies do the research, design, and testing that goes into the rims and, in many cases, the hubs they sell. Many make, assemble, and QC their own wheels. Other companies have subcontractors do the actual production for them using production lines and molds dedicated to their wheelsets while they as Integrateds define and oversee the material, construction, assembly, and testing methods that go into making these wheels.

Bontrager Aeolus Pro 37 TLR – A Best Value for standard tire devotees

Performance: The Bontrager Aeolus Pro 37 is a wheelset that seems designed for the value-carbon road disc rider from the get-go. It is a capable performer in all the key areas I look for in an all-around road disc wheelset.

“Capable performer” may read like a backhanded compliment. I don’t intend it to be. It’s just that nearly all the wheelsets in the value-carbon category have one or more major performance weaknesses that limit what you can do with them and this Bontrager doesn’t.

While the Aeolus Pro 37 doesn’t perform at the level of $2000 and up carbon road disc wheelsets, its ride gave me equal or better performance across the board compared to other wheelsets I’ve tested within hailing distance of the Aeolus Pro 37’s $1300 price-point.

It accelerates well and climbs without restrictions. It was plenty stiff enough for me doing either of those efforts and when I powered up for some town-line sprints.

Shod with 25C Continental Grand Prix 5000 tubed tires at 70 psi for my roughly 145lbs/66kg weight, I found this Aeolus Pro 37 wheelset’s comfort and handling good – neither outstanding nor lacking.

The DT Swiss 350 rear hub freewheels with nary a whisper, allowing you to enjoy the peace of your ride or the calls from paceline mates. Audible preferences aside, they perform inconspicuously, neither rolling or engaging noticeably better or worse than most hubs in its price range.

I rode these wheels with standard clincher tires and tubes and I’d recommend you do as well. Bontrager includes a cloth-like strap that simply stretches over the wheel’s sidewalls and snaps into place over the rim bed’s spoke holes.

To go tubeless, Aeolus rims require plastic strips that added over 100g to these wheels and aren’t easy to install. I snapped one and couldn’t get the other one centered correctly. You can also use rim tape to seal the beds for tubeless or tube-type tires, but that takes a bit of experience to get right.

I also found installing my recommended Continental Grand Prix 5000 TL tubeless tires was a lot of work to mount and more work to get off than you’d ever want to deal with on the road. That’s just what happens with this tire and some rims, but this is one of those bad combinations. The tubed Grand Prix 5000 version mounts easily.

While I recognize everyone has different tastes and therefore don’t usually share my opinion on the looks of a wheelset, I will say that if you prefer stealthy looking, matt finished rims with sufficient badging to let people know what you are riding, these Bontragers will be right up your alley.

Design: As with most bike wheels introduced lately, this model year 2020 Bontrager Aeolus Pro 37 TLR wheelset is only made with a disc brake option and is “tubeless ready”.  As per my comments above, I’d recommend you ride it with a tubed-tire setup.

The wheelset with the easy-to-install cloth-like straps for tubed tires weighed 1519 grams on my scale. With the plastic tubeless strips, the weight increased to 1648 grams.

The rims I rode measured 21.2 mm wide on the inside (between the rim hooks) and 27.8 mm on the outside near where the tire and rim join. With the 25C Continental Grand Prix 5000 tubed tires at my benchmark 100psi, the tires measure 27.6 mm wide. At a more comfortable 80psi, they run 27.4 mm.  True to its name, the rims measured 37.0 mm deep.

The carbon rim’s profile starts off on the inner spoke edge with a softened V profile and quickly adopts a U shape as it travels toward the outer tire edges. The spokes are bladed DT Swiss Aerolites attaching to the rim with external alloy nipples. The hubset is also a DT Swiss branded 350 model.

Quality: While I’ve usually found Bontrager wheels to be very well built, the easy-to-break, hard-to-center tubeless rim strips that I wrote about above were disappointing.

The rim and hub shell finish are first-rate. The decal labels also appear to be well adhered and integrated nicely into the rim design.

Bontrager’s crash replacement policy for these and all their carbon wheels is very strong. They will replace or repair your wheels for free within 2 years of when you bought them no matter how they get damaged and provide a 50% discount to repair or replace them for as long as you own them after that.

They offer a lifetime materials and workmanship warranty. You can also return them if unused within 30 days for a full refund.

Price: You can use these links to order the Bontrager Aeolus Pro 37 for USD$1500, £1250, €1400 direct from Bontrager or from Sigma Sports.

For a slightly deeper option better suited for wider tires and maintaining higher speeds on flat and rolling terrain, I suggest you consider the Pro 37’s big brother, the Bontrager Aeolus Pro 51 reviewed below that sells for the same price.

Zipp 303 S – A Best Value for tubeless road disc riders

Performance: If the Zipp 303 S Tubeless Disc-Brake wheelset I rode for this review didn’t have the Zipp logo on the side of its rims, I wouldn’t have guessed it was from Zipp.

It has better than average lateral stiffness and average vertical compliance (aka comfort). That’s the opposite of most every Zipp wheelset I’ve ever ridden, and I’ve ridden quite a few in the 202, 303, and 404 series.

The high lateral stiffness is certainly welcome. Over the years, I’ve suggested to many larger or heavier than average readers that they go with a wheelset that is stiffer than those from Zipp. Lateral stiffness also translates to good handling in these wheels and effective climbing for a wheelset of its weight.

Less than Zipp-like comfort in the 303 S isn’t a knock per se and it’s certainly not an issue. These are more like the comfort of the average mid-depth carbon wheelset. I did many 50 mile rides on them without any compliance-induced fatigue. It’s just that I had just gotten used to Zipp wheels being supremely comfortable.

You can certainly make these wheels ride more comfortably by using a 28C tire. But you’ll pay a speed penalty doing so, much as you do with nearly every other wheelset these days as the tires will be wider than the rims and greatly diminish the aerodynamic performance. For more on this topic and tires I used and recommend against for these wheels, see the details in my dedicated review of the 303 S here.

Despite their 45mm depth, I felt only a small amount of “free speed” with the narrower 25C Schwalbe tires mounted on the 303 S. The pedaling effort (aka “watts”) I put into creating forward momentum with the 25C and 28C Zipp tires didn’t feel any easier to maintain as it does with more aerodynamic wheel-tire combinations when my speed gets above 20mph.

The 3 pawl Zipp 76/176 hubset is one of the few design aspects or components that carry over from the 302. It’s pretty basic and pleasantly quiet and there’s certainly nothing objectionable about it. But don’t expect to get the same performance and smooth-rolling of the Cognition hub Zipp puts on its NSW wheels just because they have the same logo.

The 303 S wheels did take notice of crosswinds but didn’t trouble me much about them. That was a very good thing as they climbed very well for a wheelset their depth and weight.

Also new for Zipp, the 303 S wheelset along with the new 303 Firecrest is the first in their new gravel wheelset category. While what qualifies as a gravel or a road or cyclocross wheelset or one that’s well suited for all those disciplines these days is debatable, the 303 S internal width helps to make the gravel argument.

From my testing, however, they ride on gravel more like most 21mm road disc wheels that are only slightly narrower than this one’s actual 22.5 mm internal width (per my measurement) and not the 25C rim width platform I’ve found is best for 35mm and wider gravel tires.

Many ride 21mm (and 19mm and even 17mm) road wheels on gravel these days and you can certainly ride these as I did for many miles on various types of dirt and gravel terrain. But, these and 21C wheels lack the comfort and handling of wider, dedicated gravel wheels.

Because it’s a Zipp wheelset, I’ve reviewed it as critically as I would any wheelset that sells at historically Zipp-like prices. But this new Zipp wheelset sells for far less and should be compared to those from other brands in this review of value-carbon wheels that sell in the same price range.

Given its combination of stiffness, handling, climbing, and acceleration performance better than most others in this category along with Zipp’s broad dealer service network and lifetime warranty, this Zipp 303 S is a value-carbon wheelset Best Value pick for those already or willing to ride with tubeless tires on their disc brake bikes.

Design: These Zipp 303 S tubeless disc brake wheels have hookless rims that require you use tubeless tires. While most tubeless wheels these days have hooked rims that will lock in the flexible beads of tube-type clincher tires and give you the option to choose between going tubeless or tubed, you can only use tubeless tires on these wheels. If you aren’t on board with that, these wheels aren’t for you. And there is no rim brake version.

The wheels weighed 1556 on my scale with pre-installed rim tape but no tubeless valves. They measured 45.2mm deep with a 22.5mm inside and 27.5mm outside rim width. The rim profile starts V-shaped at the spoke bed and quickly transitions to more of a parallel U shape.

Zipp uses their 3-pawl 76/176 hubset on the 303 S, one they used previously on the first 302 and 303 Firecrest disc brake wheels. They use 24 bladed, j-bend spokes on the front and back with external nipples.

The rims are made and the wheels are assembled in SRAM’s Taiwan factory

Quality: Like many lower-priced wheelsets, the hubs use push-in end-caps. That’s usually not a problem but if you frequently remove the wheels and change the tires to go from a road to gravel set up as the 303 S are intended for you to do, it’s not difficult for the end-cap on the freehub to pull off from the weight of the cassette. It happened to me on a couple of changeovers and I had to scramble to put a pawl or two back in place. I was more careful after that.

Otherwise, the rims appear to be well-built and the wheelset assembled without issue.

Most notably, Zipp now gives the original owner a lifetime warranty on materials and workmanship for model year 2021 and later components including these wheels. They also have a “Life Happens” crash program that discounts repairs 50% for damages caused during transportation, accidents, and misuse.

As with the other integrated wheelset makers and different from those I put in the Regionals, Branded, and Manufacturers category, Zipp has an extensive dealer network and you can bring your wheels to any of them for service or warranty regardless of where you purchased them.

Price: The 303 S wheelset sells for US$1300, £875, €1120, a very un-Zipp-like price. That’s less than what you’d pay for just the front wheel of their top-of-the-line NSW wheels, US$900 below what was the price of their just replaced 303 Firecrest disc wheels, and US$200 less than the 302 disc wheelset that the Zipp 303 S is replacing.

ENVE 45 – Well-performing wheelset from a prestige brand

Most of us want a carbon road disc wheelset that does nearly everything well but can’t find one that also fits our preferred budget. So we either reduce our performance expectations to meet our budget target, increase our budget to hit our performance target, or keep looking and waiting for that one wheelset that meets both targets.

Enter the ENVE 45, a US$1750/£1850/2220 carbon road disc wheelset from the company that makes some of the best performing wheels I and my fellow testers have ridden.

Before introducing the Foundation road wheel line that now includes the ENVE 45, a deeper ENVE 65 aero road wheelset (reviewed here), two gravel wheelsets, and an MTB one, all ENVE road wheels were part of the high-end crowd I call  “performance-carbon” wheelsets. As the category name suggests, it includes the best performing wheels but they also sell for between $2000 and $3000, some more.

The ENVE 45’s US$ price puts them outside the range for the value-carbon wheels in this comparative review.

While most wheelsets also line up in value-carbon or performance-carbon categories in £ or € denominations, ENVE wheels sell for far more than the exchange rate would suggest when they leave the States for reasons I can’t explain. So at £1850 and €2220, the ENVE 45 lands in the lower end of the performance-carbon price range. Sorry chaps, mates, et mes amis. 

Performance: So how does the ENVE 45 rate on the performance and value?

My headline – Well-performing value-carbon wheelset from a prestige brand at a modest price premium.

And, my sub-head – Not on par with the best performance-carbon wheels that cost a good deal more.

You had hoped for better? Me too. I was hoping for a performance-carbon level wheelset at a value-carbon price. The ENVE 45 isn’t it. Sadly, I haven’t found that wheelset anywhere as yet.

Most value-carbon wheels we’ve tested have at least one, and often several performance weaknesses. They are best when you are willing to compromise away things that really don’t matter as much to you.

So, maybe they aren’t super comfortable unless you put on tires that are wider than the rims. But since you aren’t all about going fast, you trade off some speed for added comfort and better handling at a good price.

Or perhaps they don’t respond with the kind of snap you’d read about from lighter wheels or make it easier going uphill. But since you aren’t racing and know that losing only 2kg (4.4 lbs) in your gut rather than 200 grams in your rims would make you a lot faster and get you to the top of climbs sooner, you pass on paying a grand more for snappy and light wheels that’d be wasted on your rides.

And maybe the price is so attractive that you look away from the warranty that gives you less than a two-year term, or covers only the rims, or makes you pay to ship it to another continent if you want to make a claim after 3 months.

Compared to others in the value-carbon wheelset category, the ENVE 45 Foundation wheels perform pretty well on nearly all of my performance criteria. And, they carry the ENVE brand prestige, albeit with rather understated decals on their matte black rims. Those rims are made and the entire wheels are assembled in the US, a point of pride and preference for some, and carry a longer-than-most 5-year warranty.

The ENVE 45 is plenty stiff and handles most terrain – flats, rollers, climbs – competently. They aren’t snappy but neither are they slow off the mark. They don’t favor one type of terrain like hills at the expense of another like flats or vice versa. They are true “all-arounds”.

Using the same ENVE alloy shell hubs with DT Swiss-like star ratchet internals that the company puts on their best-performing wheels, the ENVE 45 wheelset rolls smoothly and freewheels relatively quietly while engaging as fast as you need for a road wheelset.

With the right tires, they also handle confidently. Because they use hookless rims, you can’t put every tubeless tire on the ENVE 45 (and definitely not the Continental 5000 TL). But, per ENVE’s approved tire list (see here), you can use most including many I’ve reviewed and favor (see here).

If you are committed to using 28mm wide tires, know that the Bontrager R3 Hard-Case Lite will be the most aero choice among 28mm tires I’ve tested.

The 28mm Schwalbe Pro One TLE and Specialized S Works Turbo Rapid Air once mounted and inflated to my test pressure of about 60psi will measure about the same width as the rims. But since these are hookless rims, the tire-rim intersection will be a bit smoother than one with a hook so won’t likely have a big, negative aero effect.

More importantly, I rode the ENVE 45 with a few different 25mm tires mounted at different pressures and couldn’t find a comfortable combination. While as fast or faster than most of the value carbon wheels of similar depth, these ENVE Foundations didn’t offer the amount of added momentum or free-speed of performance-carbon wheels of similar depth or the deeper value-carbon, Bontrager Aeolus Pro 51 TLR.

The ENVE 45 also got pushed around a bit in the heavy, spring crosswinds we have in the Northeast US. Surprising for an ENVE wheelset but not much different than many value-carbon wheels.

If you are a multi-surface rider, know that these aren’t also gravel wheels. With a 21mm internal rim width, they really aren’t wide enough for more than smooth dirt roads where you’d use a 32mm wide tire at most. ENVE makes the AG25 (review coming) that is a dedicated gravel wheelset in their $1750 Foundation range. It has a 25mm internal rim width that supports gravel tires as wide as 45mm for the kind of comfort and handling you’d want on any class of gravel.

Compared to better all-around wheels in the more expensive performance-value category, the ENVE 45 doesn’t compete. They aren’t as responsive, don’t hold their speed as well, aren’t as impervious to crosswinds, don’t climb or handle any better, and are generally less compliant (comfortable).

But, if you are looking for a value-carbon wheelset that does most everything as well or better as others in this category, carries a bit of brand prestige and a superior warranty, and you are willing to pay a few hundred more for all of that, then the ENVE 45 is a good choice.

Design: As with most new wheelsets these days, the ENVE 45 is strictly a disc brake wheelset set up for Centerlock attachment for your rotors, and 12x100mm front and 12x142mm rear hub holes for your thru-axles. And like more new disc brake wheelsets, the ENVE 45 rims are hookless. I included a link to compatible tires in the section above.

The rims themselves measured 21.1mm inside width, 28.0 outside and 45.2mm deep on the wheels I bought to test for this review. With the ENVE alloy shell hubset and a Shimano 11 speed or HG freehub, my wheelset weighed 1557 grams. That’s right on ENVE’s claimed 1561 grams. They quote a 20g lighter total weight with a SRAM XD freehub. It is also offered with an Industry Nine 1/1 hubset.

Each wheel is laced with 24 bladed, j-bend Sapim CX Sprint spokes that are secured to the rim using internal nipples.

ENVE sends valve stems, nuts, and ample rim tape for you to install yourself. Lockrings are not included

Quality: These and all ENVE wheels come with a 5-year material and workmanship warranty, a 2-year paint warranty, and lifetime incident protection warranty for the carbon covering damage covered during riding, crashing, or driving your roof-mounted bike into the garage.

I will note that, in my experience, ENVE rims aren’t as polished and uniformly shiny as those you’ll find from other brands. Some I’ve reviewed come through with thin, off-white residue lines along small sections of the spoke edge of the rims. I don’t find it an issue but if you a cyclist that washes and polished your frame every 3 or 4 rides, you may.

Price: The ENVE 45 wheelset is hard to find online these days. Look for them at some of ENVE’s largest online dealers that are also stores I recommend because of their competitive prices, product selection, customer satisfaction, and reader support. They are most likely to have or get stock first in their region until sold out and restocked again.

Reynolds AR41 – A disappointing successor to the well-liked Assault

Reynolds AR41

Performance: As the successor to the similarly priced Assault I recommended for years as a best value, I expected the AR41 performance to get better by taking advantage of the many carbon wheelset advances in the industry during the Assault’s long run. Instead, the AR41 is a disappointment.

While the AR41 is a stiff wheelset, seemingly stiffer than the Assault, both Nate and I found it lacked the lively responsiveness that set the Assault apart from other value-carbon wheelsets. The hub engages quickly but you don’t get that same snap, or any snap at all actually, that you got from the Assault when accelerating.

The braking is also poor both on dry and wet roads using the recommended blue pads that come with the wheels. Nate and I also tried a set of Black Prince pads with no better results. The AR41 squeals after braking for a while on dry roads and is a bit scary braking on wet ones. The rims are stiff enough to allow you to set the pads close for better modulation but you have to squeeze your levers so much more on these wheels than most others to build up the braking force needed to slow them that modulation really isn’t a consideration.

The AR41 braking is clearly a step down from the Assault’s performance which was average compared to other carbon wheelsets designed mid-decade. The braking performance gap is even larger between the AR41 and what we’ve become used to from textured and treated brake tracks on today’s more expensive, performance-carbon wheelsets, less expensive alloy upgrade ones and certainly the disc brake experience.

At 19mm internal and 27.5mm external, the AR41 rims are 2mm or so wider than Assault but aren’t any more comfortable. They aren’t harsh but they also aren’t comfy on long rides even if you run them tubeless and at reasonably low pressures in the 60-75psi range that Nate and I experimented with.

AR41 handling is slightly improved over the Assault. You get a confident, planted feeling likely due to the stiffer, wider platform. It isn’t on par, however, with the better, more expensive, performance-carbon all-around wheelsets. The AR41 also doesn’t get pushed around as much in the crosswinds as the Assault did but again, not as good on this dimension as the better, performance-carbon wheels.

There doesn’t seem to be any “free speed” coming from the AR41’s hub or rim profile to help you maintain your momentum going downhill or riding the flats at 20mph+. The freehub is also a little loud, something I don’t prefer but that some people like.

Design: I measured the AR41 at 1521 grams and 40.5mm deep. The rim is tubeless-ready, has a U-shaped profile and measured 19.0mm wide between the bead hooks (“internal” width) and 27.5mm at the brake track (external).

The Reynolds brand hubset has a 10-degree engagement rear freehub. The Sapim Sprint spokes are rounded and attach to brass nipples.

The AR 41x and other ARx series wheels sell for $250 more ($1700) and use the same rims, a lighter hubset with the same engagement, and bladed Sapim CX-Sprint spokes. The AR41x’s 1480g claimed weight is 65 grams less than the claimed weight of the AR41 tested here.

Quality: Reynolds has one of the best set of policies in the wheelset business. Despite what I wrote about their performance, would you like to test out the AR41 wheelset yourself before committing to them? If you live in the US or Canada, you’ve got 30 days to return them for a full refund and they’ll even pay for shipping if you decide it’s not for you.

While a 2-year warranty is standard for most companies, Reynolds gives the original owner a lifetime warranty, promising to replace or repair the wheelsets if any material or workmanship issues arise. The crash protection policy also lasts for the life of the wheelset. Regardless of how they were damaged, Reynolds will provide you a 50% discount on new wheels. You can also purchase an upgrade to assure your wheelset will be replaced at no cost no matter how it gets damaged.

We evaluated these wheels shortly before Reynolds was sold. All the policies mentioned above remain in place. Reynolds’ telephone tech support line, however, is no longer operating.

Bontrager Aeolus Pro 51 TLR – Quiet comfort amidst lackluster responsiveness

Performance: I had high hopes going into our testing of the USD$1500, £1250, €1400 Bontrager Aeolus Pro 51 TLR wheelset. We rated its shorter and similarly priced sibling, the Aeolus Pro 37 reviewed above a Best Value for its capable range of performance. And our review of the Aeolus Pro 51’s more expensive twin, the Aeolus RSL 51 that shares the same rim profile carried the headline: The Definition of an All-Around Road Disc Wheelset.

I and probably many of you keep on the lookout for that value-priced wheelset that rides nearly as well as one that costs twice as much. Using a set of performance criteria (not specs) to evaluate wheels, my fellow testers and I have ridden over a dozen value-carbon road bike wheels (and another half dozen gravel ones) over the last few years in search of one that would save you a bucket full of money without giving up more than a shot glass worth of performance. 

Unfortunately, the Bontrager Aeolus Pro 51 isn’t it.

Like all but a few wheelsets in this price range, the Pro 51 performs adequately in some areas and less so in others. From the rides that fellow tester Nate and I did, however, the Pro 51 doesn’t match or approach the overall performance we enjoyed of its RSL 51 sibling or the balance of good performance across areas like its shorter Pro 37 kin does.

Comfort is the Aeolus Pro 51’s biggest strength. Its wide rim profile allows you to run 28mm tires without sacrificing aero performance while keeping the pressure low enough to soak up the bumps on paved, poorly paved, or unpaved roads quite nicely.

True, the right tire and pressure are a big part of enjoying a comfortable ride these days. But I’ve ridden enough wheelsets, especially in this value-carbon price range where the rim/spoke/hub component choices, lacing, or assembly didn’t enable enough vertical compliance in the wheels for a comfortable ride regardless of the tires and range of pressures I tried.

The Pro 51 felt planted in corners though accelerating out of them was underwhelming. They’re stiff enough to confidently get you through but not responsive enough to get you flying out.

That lack of responsiveness also showed up during acceleration efforts. They were not at all lively. It took a lot of effort to get them up to speed.

Once up to speed, it took more effort to keep them there compared to similar depth wheels at this price point and more expensive ones. That was disappointing since the Pro 51 uses the same rim shape as the RSL 51.

While aero performance, which we judge based on our ability to maintain momentum in the 20-25mph/32-40kph range for the RSL 51 was good but not exceptional compared to top-performing all-arounds, the Pro 51 isn’t on par with the RSL 51.

The common rim profile gene did show up in the Pro 51’s good stability in side winds. That’s a welcome benefit if you ride where it is regularly windy.

Climbing with the Pro 51 was a drag, figuratively and literally. Even riding a course with rolling hills took more effort than a wheelset this depth should. 7% grade climbs put me in the hurt locker the way 10%+ ones normally do.

All of this made me feel like I had “dead legs” when riding the Pro 51. I do get those days regardless of the wheelset and certainly feel that way when trying to climb or ride aggressively on most 60mm deep wheels rather than the straight flats they are designed for. But, I should feel better than that on a good set of all-around wheels of the Pro 51’s depth and profile.

Nate put a finer point on it, saying the Pro 51 wheelset’s responsiveness was “dull.”

Design: The Aeolus Pro 51 measured 1625 gram weight likely contributes to its relative lack of responsiveness, acceleration, and climbing ability. That measurement is with about 15 grams of tubeless rim tape and no valve stems. If you instead install the 60-gram per wheel plastic tubeless strips that Bontrager includes in the box, well we’re getting into stock wheel weight territory.

Even with the TLR rim tape, the Pro 51 is almost 200 grams more than the RSL 51 (1441 grams measured) and even 50-100 grams more than my top-rated aero wheels that are 10mm deeper and, well, more aero.

I don’t know how much of that extra weight is in the rims where it matters most vs. in the hubset. Bontrager uses the DT Swiss 350 hubs in their Pro line of wheels which, while heavier than the DT Swiss 240 EXP, are infinitely quieter. Quieter as in absolutely silent.

While there may be a performance difference between the 240 and 350, I can’t feel it on the road. But I sure do notice the solitude of a quiet freehub.

As mentioned, the Pro 51 rims are wide measuring 23.2mm inside and 30.9mm outside with an actual depth of 51.5mm.

Quality: As with all Bontrager carbon wheels, their crash replacement policy and warranty programs are very strong. They will replace or repair your wheelset for free within 2 years of when you bought it no matter how it gets damaged and provide a 50% discount to repair or replace them for as long as you own them after that.

They also offer a lifetime materials and workmanship warranty. You can return them if unused within 30 days for a full refund.

Generally, I’ve found Bontrager wheels to be well built and long-lasting. The DT Swiss hubs are proven.

If you want to use these tubeless, I recommend you tape the rims rather than use the plastic strips that come with the wheels. While you need to buy Bontrager’s $25 TLR Rim Tape separately from their site, it’s both lighter and the best tubeless rim tape I’ve used to date. Beyond their excessive weight, the plastic strips are a PITA to install and center and I’ve had them crack on me when installing some before.

Hopefully, Bontrager will start including rim tape in the box at some point. They do include easy-to-install cloth rim straps if you plan to use clincher tires or tubes instead of sealant in your tubeless tires.

Price: You can use these links to order the Bontrager Aeolus Pro 51 TLR wheels direct for USD$1500, £1250, €1400 from Bontrager or at Sigma Sports.

2. Regionals 

Regionals use a similar selling approach as the Integrateds mostly using online stores and local bike shop dealers but also through sales from their web store. They sell a far smaller range and number of products than the Integrateds with wheelsets being their primary focus. Most also sell performance-carbon wheels as well as wheelsets for mountain biking, cross, and gravel segments.

These companies design their rims and some of the hubs used in their wheelsets. They own their rim molds but mostly have others do the production of their wheelsets.

As the name suggests, Regionals sell through dealers to cyclists in a specific geographic region. The value-carbon wheels I’ve evaluated in the past for this review have been replaced by newer models. I’ll work on getting some of those in for testing and add them to this section.

 

3. Branders

Branders create equity or value by building their businesses around a name that customers come to recognize and equate to offering unique attributes and benefits to them. The value of these brands in the minds of cyclists allows the companies to successfully sell their products directly rather than needing the value a distributor and dealer network can bring promoting the company’s wheelsets through their own brand, sales, and marketing efforts.

The wheelset Branders I’ve found didn’t start with rim or hub expertise to design or engineer their own wheels. While some claim to have built that expertise, they still depend largely on their ability to source the design and manufacturing of their wheelsets and market their wheels to fill the needs they originally saw in the market and have built their brand around.

For most of the Branders of value-carbon wheelsets, an element of their brand has been built around the need in the market for lower-priced wheelsets, carbon or alloy. Beyond that, they have differentiated themselves from other branders by, for example, the suitability of their wheelsets to the road and weather conditions where they are based or their purported technical insights and event focus or the wide range of wheelsets and other components they sell.

FLO, Hunt, Scribe and many other Branders use a pre-order model. They batch orders from their suppliers and receive shipments about once a month. Unless they have stock of the wheelset you want leftover from their last shipment, you reserve your wheelset with an advance deposit or full payment and then have it shipped to you when the new batch arrives. Depending on demand and timing, that means you could get your wheelset shipped immediately or wait a month or two from when you order to when you are riding it.

Scribe Aero Wide+ 50-D – Loud, aero, and unexpected

Scribe Aero Wide+ 50-D

Performance: If you really don’t like the sound of a really loud freehub when coasting, the Scribe Aero Wide+ 50-D wheelset really isn’t for you.

I’m not talking about what you hear coming out of the latest generation DT Swiss 240 freehub or the louder yet distinctive chordal sound of a Chris King R45 freehub. No, the Scribe freehub is a far louder, lower pitch noise that almost sounds angry.

Other riders told me not to coast near them, based on their hand motions because I couldn’t hear them, at least until I started pedaling again. My fellow tester Miles heard the comments too from those in his group when free coasting down fast downhill.

And yes, I tried to quiet the hub using the grease and video instructions Scribe sent me for that purpose. I noticed little difference.

I go into this first and in some detail because it’s the most distinctive characteristic of this wheelset.

If none of that bothers you, or you prefer loud freehubs as I know some do, the Scribe Aero Wide+ 50-D is a great value-priced, carbon wheelset option for fast riding and racing on flat and modestly rolling terrain.

Miles and I found these Scribe wheels hold their momentum well at speed on straight sections. They are also plenty stiff enough to give you the confidence to lean into a corner, ride through it, and power out at high speeds.

If you’ve got the watts of a racer like Miles, these Scribes are responsive and fast enough to cover most any accelerations. For me, more of a B group rider without the turbo boost power of a racer like Miles, their response felt more like a slower reacting, more typical aero wheelset.

When the road pitches up, both of us found the wheels struggled, as do many aero wheelsets. Rolling courses with long yet modest hills make you work hard on the Scribe Aero. Short kickers of 7-10% really slow you down.

For me, the aero wheelset analogy extends to my need to also lean these Scribes into steady sidewinds to stay on my line. When I got hit by gusts, I couldn’t hold it.

Miles had a better experience, finding the sidewinds didn’t affect him much, and performed better than others he’s tested. While we weigh more or less the same, the winds were highly variable during our spring testing perhaps leading to our different reactions.

With a good set of supple, tubeless tires inflated lower than you might normally set them, the Scribes can be quite a comfortable wheelset on good roads and bad. We tested them with both 28mm Schwalbe Pro One TLE and 28mm Continental Grand Prix 5000 S TR tires at pressures ranging from 55psi/3.8bar to 65psi/4.5bar for our 148lb/67kg to 155lb/70kg body weight.

The Contis at the lowest inflation pressure was the most comfortable combination.

Design: I measure and weigh wheels when they first arrive, share none of that info with my fellow testers, and forget most of it myself with all the gear traffic coming through my door. That usually turns out for the best as not knowing the specs limits the performance bias we might bring into our test riding.

That certainly made sense for this wheelset. The specs and most of the “Aero Wide+ 50-D” name suggest very little about how we found that these wheels perform.

At 1529 grams measured with pre-installed tape but without the valves (vs. the claimed 1448 grams) and 50.5 mm depth, they spec out more like an all-around wheelset than an aero one.

Measuring 29.6mm externally near the tire edge of the rim, 30.2mm at their widest point, and 21.1mm internally, these wheels are wider than some but not nearly as wide as many that provide the kind of handling and comfort these Scribes can.

So the Wide+ and 50 in their name might suggest a different type of performer than what we found. If they drop those parts of the name and simply call it the Scribe Aero D, they’d have a name that better describes this wheelset’s performance. (This probably wouldn’t work with the rest of their product names, however, as all of their carbon disc brake wheels are called Aero Wide+ followed by the rim depth number ranging from 32mm to 80mm).

And despite all the attention the loud freehub with its glossy hub shell and white script Scribe logo calls to this wheelset, the matt grey finish on the rims we tested is quite a modest look. Miles calls them “boring.” They look ok to my style-blind eyes but certainly are at odds with the boisterous, flashy hubs.

While I’m really out of my depth trying to psychoanalyze a set of wheels, the unexpected nature of the Scribe’s performance compared to its specs and its aural and visual aesthetics seem to make it, behaviourally if not technically, an eccentric wheelset. The freehub almost calls out at you, saying “look at me.” When you do, the rim finish seems to respond with “there’s nothing to see here.”

Setting aside my psychobabble (or should I say cyclobabble?), this Scribe is another example of why I focus on performance and not specs in our reviews.

Quality: Scribe’s warranty policies are better than many that sell wheels at similar price points especially those sold direct by overseas manufacturers.

Specifically, they offer a 3-year warranty against material or workmanship defects and a 50% crash replacement discount for the life of the wheels. Should you need or want them, they will also send you a set of replacement bearings in years 2 and 3 of your warranty free of charge. All of these apply to the original owner.

Miles and I didn’t experience any quality issues during our several-month test period. I did open up the freehub to grease it and to my untrained eyes, it seemed to be well-built. Scribe includes valves and lockrings along with spare spokes, nipples, and other parts to adapt the wheels to older disc brake rotor technologies.

Price: Available direct from Scribe, the Aero Wide+ 50-D wheelset sells for US$1100, £870, €1000. While shipping is free, Scribe notes the price “may be subject to additional customs charges” and indeed mine were though Scribe told me that it doesn’t happen often.

FLO 60 – Pay no attention to the name; it may fool you (replaced by the 64 AS)

FLO 60

Performance: FLO wraps its brand around speed and, based on their marketing appears to target the triathlete as one of if not their primary customer segment. With that in mind, testing this 63.0 mm deep carbon value rim brake wheelset (thanks Mark L!) seemed to be a good way to see how well FLO’s product performance lived up to the brand image it tries to create and how it compares against equally deep performance-carbon wheelsets that we reviewed here.

Bottom line, the results of the test riding Nate and I did were not what I would have expected.

The FLO 60 is clearly a stiff wheelset. Nate called it the stiffest wheelset he has ever ridden, stiffer than performance-carbon aero wheels like the Bontrager XXX 6 and ENVE 5.6. We also found that it was very responsive, essentially on par with the ENVE 5.6. This was surprising for a wheelset of this depth and 1728 gram measured weight, but perhaps not when you consider how stiff it is. That stiffness translates your power very efficiently on a climb.

But wait! Isn’t this an aero, triathlon/TT wheelset or at least front wheel for a 60/90 wheelset combination? Accelerating and climbing aren’t what you do much of when you race those events.

Yes, you could also use the wheels for crits where you accelerate often so we’ll take that performance benefit. And there are plenty of time trials that include rollers so this wheelset’s climbing performance is another nice-to-have.

But how good are the FLO 60’s aerodynamics and its crosswind management? These are perhaps the two most important performance benefits triathletes and other speedy flatlanders want in their wheels.

Uh, not so good. Nate summarized it well when he said the FLO 60s didn’t perform consistent with their rim depth. “I didn’t feel the same exhilaration of flat-ground, momentum-sustaining performance as I did with the ENVE 5.6 or Bontrager XXX 6 or Zipp 404 NSW or even the [45mm deep] 303 NSWs.”

I too was non-plussed by their ability to hold speed. They seemed no better than the 45mm-50mm depth wheels I’d tested for this review and our performance-carbon all-around rim brake and disc brake wheel reviews.

They also didn’t manage the crosswinds nearly as well as modern performance-carbon rims of similar depth. Nate found the crosswinds noticeable but not problematic while riding the FLO 60. I found they didn’t respond in any consistent way and took some real mental energy to keep adjusting the front wheel to my chosen line.

Neither of us found the wheels very compliant. Nate called them “harsh”. My descriptor was “horrible.” Yes, we both prefer to ride our wheels tubeless and at lower pressures and the FLO 60 are only made for tubed tire clincher tires. The rims are certainly wide enough (18mm internal, 26mm external) to be comfortable on 25C tires.

Perhaps the hubs were part of the compliance underperformance. The hub-spoke-rim component system needs to work right in combination to get a wheelset that is both laterally stiff and vertically compliant. A lot of wheelsets have a hard time getting that combination right.

The hubs performed more like those on stock wheels and certainly not at the DT Swiss 240 level of many of the other value-carbon wheels in this comparative review. They didn’t roll as smoothly and the rear didn’t seem to have as many points of engagement.

Handling, likely because of the poor compliance and in spite of the great stiffness, was average at best. I didn’t feel terribly planted when cranking through a turn and coasting through one was not terribly stable.

The braking of these rim brake wheels was decent though not refined and typical of better earlier generation carbon braking performance. Plenty of braking force, minimal noise, and no squealing but not much modulation to be had. On or off.

If you do shorter TTs or races on hilly courses with good pavement, the FLO 60 would be a low-cost option to consider. Beyond that, you’ve got better choices available to you.

Design: Measured weight 1728g. Rim depth 63.0mm. Internal width 18.2mm. External width 26.0mm at the brake track and 26.6mm maximum. Essentially a V-shaped rim profile. Bladed Sapim CX-Ray spokes and a FLO VORTEX 2 hubset with EZO stainless bearings.

Quality: FLO provides standard 2-year materials and workmanship warranty. You can return unused wheels within 30 days if you decide not to keep them but you’ll pay for shipping and a 10% restocking fee to do so. There is no crash replacement policy.

Price: FLO has replaced this wheelset with their 64 AS. You can see this new $1488 model at FLO Cycling.

Hunt 50 Carbon Aero Disc – Buzz Overwhelms Performance

Performance: Hunt generates a great deal of buzz for its products and brand, seemingly as much as or more than some wheelset sellers many times Hunt’s size and experience. I bought these wheels looking to experience how they actually performed, separate from the buzz.

It turns out that you can’t separate the buzz from the performance. Unfortunately, it’s the freehub buzz rather than the marketing buzz that is inseparable from these wheels.

Simply stated, the freehub sound on the Hunt 50 Carbon Aero Disc is one of the loudest fellow tester Miles and I have ever heard from wheels we’ve tested or ridden alongside. Far louder than a Chris King or i9 that are known for their distinct and loud freehubs but nowhere near the refined fuller frequency sound from the multiple points of engagement those hubs offer.

The freehub is so loud that you can’t have a conversation with a friend while coasting on these wheels. I tried it. Could hardly hear a thing he (or I) was saying.

Miles, a fan of distinct sounding freehubs, wrote in his test report: “It was not quite a chainsaw, but it was close.”  With tongue firmly planted in cheek, he added: “It was cool and will turn some heads, but I could have used a slightly quieter freewheel sound.”

My more practical concerns – 1) being able to communicate with fellow riders in a paceline and 2) wrecking the peace I so enjoy (and deserve) going downhill after a hard climb.

Aside from the freehub, the Hunt 50 Carbon Aero Disc performance is a prime example of what separates most value-carbon wheelsets from higher-priced performance-carbon ones.

Unfortunately, it’s not just the price. Rather, this wheelset lacks the comfort, stiffness, climbing, and handling qualities of performance-carbon wheels. It also underperforms other value-carbon wheels that have a strength in one or two areas that might align well with what you are looking for and cause you to overlook other weaknesses because you’re getting the wheels at a lower price.

Though it was not outstanding, the 50 Carbon Aero Disc wheelset’s aero performance was probably its strongest characteristic. They feel more like a 40mm deep wheelset with some sense that your momentum is being sustained but not to the level of a similar depth value-carbon wheelset like Bontrager Aeolus Pro 51 TLR Disc

You also feel a little bit of push from crosswinds, though nothing to move you dramatically off your line.

For those of you that enjoy sprinting hard out of the saddle, Miles found these Hunt’s responded well and shot forward with purpose. Going uphill, however, they felt quite average to both of us and offered no help from their lateral stiffness or aerodynamics.

Design: The Hunt 50 Carbon Aero Disc rims measured 50.1 mm deep with 19.5mm internal and 26.5 mm external widths. The internal width I measured was considerably less than the 21.3mm width Hunt currently lists for these rims on their site. The external widths were the same as what is listed. It’s possible that Hunt changed the source or design (or both) of these wheels in the five months’ time between when I ordered and reviewed them.

The rims have more of a V than U-shaped profile. My benchmark Zipp Tangente Speed RT25 tubeless tires set up about 0.5mm narrower than the rims at 80psi. The tires went on the rims easily using the rim bed’s deep center channel though I needed to use my compressor to inflate them.

Hunt uses bladed and butted Pillar spokes on these wheels, 20 in the front and 24 in the back. The hubs are Hunt branded Race Season Disc straight-pull with 7.5 degrees of engagement. Novatec has made hubs for Hunt in the past but I was unable to determine whether they make the ones on this wheelset.

With rim strips but no valves, the wheels weighed 1579 grams on my scale or about 90 grams more than the 1487 gram weight Hunt claims for this wheelset.

Quality: The wheels themselves appeared well made and had a very even matt black finish. They came with extra spokes and other spares in case you ever need to replace them.

The quality of Hunt’s service, while very polite and well-intentioned, gave me every indication that the company lacks established processes and financial controls in important customer service areas.

The set I ordered came damaged with the freehub having come through the box. It happens and was likely caused by the shipper or a customs handler rather than Hunt. The replacement set was shipped from the next monthly allotment unscathed and well packaged. Hunt initially charged my account to ship the damaged wheels back but refunded me after several requests.

Because I didn’t care for the wheelset’s performance, I decided to return them under Hunt’s 60-day tryout policy. It took me over 20 emails and several more exchanges with their online chat over a month’s time to get the wheels back and refunded.

Getting Hunt to respond to the return request, securing the shipping labels, scheduling the shipper, acknowledging the return, and then processing the refund each took at least 3 e-mail requests from my end for each of these steps. (The refund process took many more than 3.)

There were 6 or 7 Hunt advisors that responded over that time with, at times, incomplete, incorrect, or contrary information, occasionally with multiple responses from different advisors and email domains to the same email from me.

Price: When I bought these wheels, they sold for USD$1079. At last check, they sell for USD$899, £790 including shipping. They are available directly from Hunt’s online store.

 

4. Manufacturers

Manufacturers are in business to fabricate and sell carbon products including rims, wheelsets, bike frames, and other cycling components. They sell wheelsets under their own brand names and also make them to order for lesser-known brands and wheel builders. Manufacturers are based in China and are not to be confused with the Taiwanese-based carbon frame and component OEMs that make almost exclusively for major bike brands.

Manufacturers sell wheelsets to individual cyclists direct from their company websites or through Amazon or eBay stores. Most give you the feel of being high-volume custom wheel builders by giving you the choice of a couple dozen or more of their carbon rims combined with a range of brand name hub and spoke options. While they ship hundreds and some over a thousand wheelsets a month, depending on what wheelset you want built, it takes them several weeks from order to receipt of your wheelset.

I don’t know whether any of the Manufacturers I identified have particular wheelset design skills or how much CFD (computational fluid dynamics), wind tunnel or in-the-field prototype testing, or other engineering they do. They don’t make claims about any of this.

Carbon manufacturing and wheelset assembly appear to be their primary focus and competence. Reverse engineering is a skill many manufacturers of all sorts of cycling and other industry products often have and that some of these Manufacturers may also possess.

Yoeleo SAT C50|50 DB PRO Clincher/Tubeless – Laterally compliant, vertically stiff

Yoeleo SAT C50|50 DB PRO

Performance: While most roadies like a laterally stiff wheelset that transfers power efficiently to the road that is also vertically compliant to help cushion imperfectly paved paths, I found the Yoeleo SAT C50|50 DB PRO underperformed the better value-carbon wheelsets on both measures.

As a lighter and therefore less powerful rider, I’ll typically have to work hard climbing and sprinting to notice stiffness differences. With this Yoeleo wheelset, I noticed it right away. Compared to a stiff wheelset like the value-carbon Bontrager Aeolus Pro 51 TLR, the SAT C50 felt imprecise pedaling up the first modest hill I hit within a mile of my house.

When I increased the tire pressure 10 psi, they rode a bit stiffer though they still weren’t stiff. And lowering the pressure the same amount didn’t really improve the comfort.

The handling did improve at higher pressure.

After many rides at different pressures and considering the tradeoffs, I ended up riding them about 5 psi higher than I normally ride. This seemed to get me the best performance balance between stiffness, comfort, and handling for these wheels. Unfortunately, the Yoeleos still underperformed on all three of these criteria.

Strangely, however, the balanced underperformance seemed easier to get used to over time than wheelsets that were good performers on one of these criteria, say stiffness, and subpar performers in others, for example, comfort.

While 50mm deep and with a good DT Swiss 240 hubset, the SAT C50 didn’t feel particularly fast or helpful in maintaining aero speeds. While weighing only 1459 grams, quite light for any road disc wheelset of this depth, they didn’t climb or accelerate markedly better than far heavier, stiffer wheels like the Bontrager.

Design: The Yoeleo SAT 50|50 DB PRO would seem to have all the specs to make it one of the better performing wheelset. My conclusion that it is a below-par performer further proves that you can’t go on specs in predicting how well a wheelset will ride out on the road.

My 50.2mm deep test wheels weighed 1459 grams which compares favorably to the claimed weight of 1518g. Unlike many lower-priced carbon wheels that use Toray T700 standard modulus fiber, Yoeleo uses the higher modulus, higher tensile strength Toray T800 intermediate modulus carbon fiber for these wheels. With all else being equal (rim wall thickness, spoke bracing angles, hub flange diameter, etc.), this should give the wheels a higher strength to weight ratio and make them stiffer than what I experienced. Clearly, something wasn’t equal.

The rims have a classic toroid profile even more pronounced than the original Zipp 303 that was one of the originators of this shape. These Yoeleo wheels measure 26.0mm wide at the brake track and 27.7 mm at their widest point. The internal rim width between the bead hooks is a healthy 18.5mm, a bit narrower than the 19 and 21mm width you find in today’s widest rim and disc brake road wheelsets, respectively.

As with all the value-carbon wheelsets I could specify for this review, this SAT C50 had DT Swiss 240S hubs with Sapim CX-Ray straight-pull spokes.

Quality: Similar to most Manufacturers, Yoeleo’s quality policies are relatively limited. They do offer a 3-year warranty but only cover the shipping costs for the first 3 months should there be a problem. And remember, you’d need to ship the wheelset to China.

If you decide you don’t want the wheels after they first arrive, you have just 3 days to inform Yoeleo that you want to return them and here again, you pay for shipping. They offer no crash replacement policy.

My test wheels arrived true and looked well built. While I rode them less than 1,000 miles, I encountered no quality issues with them during that time.

Price: At the time I ordered these wheels (before the US tariffs on Chinese imports were put in place), they priced out at as specified at $1225. You buy them directly from Yoeleo.

Light Bicycle WR46C02

Performance: While the performance of these all-around disc brake wheels is a long way from $2000 and up models, the Light Bicycle WR46C02 wheelset with DT Swiss 240 hubs offer the most balanced performance of any in the sub $1500 value-carbon wheelset category.

That’s a qualified statement so let me break the performance down to its components and comparisons.

First, it’s not on par with stiffness, comfort, responsiveness, handling, and other key performance criteria of the better all-around carbon rim brake or all-around carbon disc brake wheelsets I’ve reviewed that will cost you $2000 or more. None of the wheelsets in this category are.

Yet, while some of the wheels in this category offer performance strengths (e.g. stiffness) relative to other value-carbon wheelsets only to be offset by comparable weaknesses (e.g. crosswind management), these Light Bicycle wheels impressed me and fellow tester Miles for doing most everything on our performance lists decently.

While not as stiff as say, the Bontrager Aeolus Pro 51 TLR Disc wheelset or as aero as the ENVE 45, these WR46C02 wheels are both adequately stiff and do help hold your momentum somewhat. Though not climbing wheels, they also go uphill reasonably well and certainly better than some of the heavyset hoops in this review.

While I haven’t found any of these value-carbon wheelsets to be in the same comfort ballpark as the performance-carbon ones, they were comfortable enough to run tubeless at the low end of my air pressure range to not wear me out when I did a 4-hour ride on them.

The handling was decent, the DT Swiss 240 hubs I speced the wheels with are relatively quiet and roll smoothly, and the rims managed the crosswinds predictably despite being an older V-shaped profile. Set up with my benchmark 25C Zipp Tangente Speed RT25 tires, they measured a mm narrower than the outside rim width which is good for aero performance.

In a flat out sprint, while not floppy, they did not feel super fast in a straight line. Instead, they seemed rather average among similarly priced wheels. While they are also made in a rim version, we weren’t able to test their braking performance since we rode the disc brake model.

It’s also worth noting that their subtle finish is attractive and the tires went on easily, sealed with only a track pump, and held air and sealant well.

Design: This wheelset tested weighed in at 1504 grams without rim strips or valve stems. Light Bicycle claims the rims weigh 435 grams though I was unable to verify that. They measured 21.3mm internal width and 28.3mm external. The rim has a classic V-shape profile and uses 28 CX-Ray J-bend spokes in the rear wheel, 24 in the front, both connected to external alloy nipples and the DT Swiss 240 hubs. You can have the wheels built with a list of more or less expensive hubs if you prefer.

Quality: The wheels looked well built and stayed true during our testing. While Light Bicycle states a 3-year warranty, the conditions of that warranty make it quite limited compared to others and don’t add up to the 3-years stated.

Light Bicycle gives you only 30 days from purchase to replace defective rims during which they pay the shipping costs. If the rim defect occurs after the first 30 days and up to 15 months, they’ll replace the rims but you have to pay for the shipping to/from their North American assembly center in Canada if you bought from there or from their Global center in China if you live outside of North America. Nothing is stated about what happens after 15 months.

If you have issues with the hubs or spokes, you need to go to the manufacturers of those parts to deal with those issues. Hub warranty terms are usually a year. There are no warranties on spokes.

Light Bicycle doesn’t warranty the workmanship surrounding the assembly of the wheels’ components. When I asked about that, they offered to write a one-year warranty on the invoice but claimed they have never had the need to provide this type of warranty.

Frankly, this warranty would make me uncomfortable buying wheels from Light Bicycle.

Light Bicycle will take care of wheels damaged in shipment as long as you refuse the shipment or make them aware of a shipment damage issue for ones that are dropped off within 10 days.

You’ve got 30 days to return unused, stock wheelsets for a refund. Non-stock orders can only be returned if there is an error made by Light Bicycle. There is a 10-25% discount on new wheels if you crash yours within an unspecified period.

Price: As specified, the WR46C02 wheelset runs $1267 if bought from their North American assembly center and $966 if purchased from their China location, not including shipping. If you live in North America, duties and taxes are already built into the price. If you don’t, those fees along with added shipping charges are added to the price. It will also take you longer to get them and cost you more should you need to return them under warranty. You can purchase them directly on the Light Bicycle website.

  • Hi. I know your reviews are honest, but I think you shouldn’t compare rim brake and disc brake wheels in the same review. For exemple, Reynolds AR41, in the disc version, just haven’t the same specs ( 21 internal), so if you want to make a comparaison with the 303s to declare which one is the best, you should rather take the comparable model. Otherwise it’s orange and apple. Thank for the good work though. (…and by the way I don’t work for Reynold’s)

  • Hi Steve ,

    I took a look at PART II as you suggested. Great info.

    I am now looking at the SC 55 DISC WHEELSET or the SC 40 DISC WHEELSET from Vision and the HED JET RC5 plus. Any suggestions or opinions are much appreciated.

    • Peter, since the wheels you’ve mentioned cover quite a range, my best suggestion would be that you take a step back and read through my post on how to choose the best wheels for you. This might give you additional guidance in picking the right wheelset for your goals, riding profile and budget. Cheers, Steve

  • Hey Steve, always very useful reviews. Have you ridden any of the Vision SC wheels, if so any thoughts on how they’d compare to others in this list? Particularly focussing on the SC 40 disc vs 303s vs Hunt 50’s for example?

  • Excellent and in-depth review! Nice work. Curious why Fulcrum wheels weren’t considered, such as the Wind 40’s. They’re in the price range “value” criteria you established. I’d be curious on your comments regarding Fulcrum.

    • Harry, So many wheels, so little time, not enough budget – we’re an ad-free, reader-supported, independent site run by fellow roadies with real jobs that have no connection to the cycling industry. That said, thanks for the suggestion and I’ll put it on the wish list. Steve

  • Thank you for in depth and thorough reviews!
    Any chance of a review of Cannondale’s Hollowgram SL KNOT 45 Carbon? Curious to see who they compare to the ENVE 45 Foundation.

    • Jarle, Do you have that Cannondale wheelset now? If so, what’s your experience with it? Did it come stock on your Cannondale bike? Does it have the AI or standard dishing? Steve

      • Hi again – thank you for answering! I do not own the Cannondale wheels. I’m looking for an upgrade to my 2021 Cannondale Synapse Carbon Disc Di2 Ultegra. The bike comes stock with Fulcrum Racing 600 DB (supposedly the same wheel as the 6 DB model). By numbers/specs the ENVE 45 f and the C SL KNOT 45 seem to be quite similar, but numbers are one thing, testing and riding is something else.

        I was not aware of the AI/standard dishing “issue”. I’ve tried to dig around the net for some information – as far as I’ve figured out only off road models Scalpel-Si and F-Si are using AI dishing – but this I do not know for sure…

        • Jarle, thanks for the additional info. FYI, while similar depth and internal width, the Cannondale wheels (USD$2200) are a good amount more expensive than the ENVE (USD$1600) at least in the US though more likely similarly priced in the rest of the world. Also, Cannondale has historically branded wheels designed and made by other companies principally to put on their bikes rather than have an inhouse wheel design division as Roval/Specialized, Bontrager/Trek, Cadex/Giant have done both for their own bikes but also to have the wheels compete in the aftermarket. That’s no knock on Cannondale but it’s just a different approach that allows those who own their bikes to have a similarly branded wheelset. I’ll check to see if I can learn where the wheels are being designed, made, tested, etc. and how aggressively they are pursuing competition with other similarly priced performance wheels. Thanks for bringing this to my attention. Steve

  • No mention of Winspace?

  • This is a very interesting article. Fact based and really well written. I have a question related to the aeolus pro 37s…you wrote that you rode them with Gp5k tubes. I am interested in riding them with 28mms. But on Conti’s site they stipulate that they should not be mounted on rims more than 19c wide. I think the bontrager wheels are 21 wide. Am I misreading something?

    • Dan, Not sure what you’re referring to on Conti’s site but 28mm tubed clincher tires should work fine on those Aeolus Pro 37 wheels. Steve

  • Thanks for the speedy reply Steve. That great. Thanks for confirming. I have included the link from the conti site so that you can view it.

    https://conti-tyres.co.uk/tyre-rim-combinations

    • Dan, thanks for the link. I can’t speak for Conti but what I see on that page is out of date with what I understand to be the 2020 ETRTO update. The prior standards used 13c, 14c and 15c rim sizes as a starting point. The updated ones start with larger, more modern rim sizes.

      There are other indications that the page is out of date. For example, while not relevant to the tubed clincher tire you’re asking about, it says on that page that “Continental recommends that you mount bicycle tyres on hook edge type rims only.” This conflicts with a statement on the web page of their recently introduced tubeless GP 5KS TR that says the 5000S TR is “now compatible with hookless rims.” https://conti-tyres.co.uk/road-and-track/clinchers/grand-prix-5000s-tr?highlight=WzUwMDAsInMiLCJ0ciJd. Steve

      • That’s great Steve. I can see quite a few people on the web have been mounting 25 and 28mm contis on 21mm and even 23mm rims and your own experience is more than good enough for me. Looking forward to getting the Aeolus 37s. I think they’ll be a good step up from my domane stock wheels which are very heavy.

  • Great review as ever Steve. I shared your feelings about the Hunt 50 Carbon Disc and ended up returning them too (although had a lot less hassle than you by the sound of it). I then tried the Hunt Aerodynamicist 44/54’s and wow what a difference. Night and day compared to the ‘standard’ wheels, especially in terms of handling and speed sustain. If anyone is looking for performance carbon wheels at value wheel price, this is the set to go for based on my experience.

  • I rode the Bontrager Aeolus 51 last Saturday and the Zipp 303S on Sunday on the same bike, same route, same weather, and both sets tubeless with 25mm tires. I felt the Aeolus to be more aero and easier to maintain speed, at the same time less affected by side wind compared to the 303S wheels. I should note, the Bontragers did have the DT Swiss star ratchet 54 tooth upgrade. I liked the Aeolus enough that I ordered at set on Monday.

  • Impressive reviews! I’ve got the Light Bicycle WR46C02 wheelset. Used for gravel, never had an issue with them. Strong and durable. But now I have been offered to pick up the Zipp 303S for a really nice price. Is it worth it to swap them for the LB wheels?

    • Bendik, depends on what you want from a wheelset that you aren’t getting now. While there are certainly better performing wheelsets for gravel than either of those which are both best on paved roads, you seem happy with what you are rolling on now. If you wanted something to climb better or provide more comfort and better handling on gravel, you can do better than both of those though perhaps not at the price you want to pay. See my comparative review of gravel wheelset). Steve

      • Thanks for your reply! So it could be an idea to use the LB WR46C02 for the road, and then buy another set like the Zipp Firecrest 303 to use for gravel riding?

        • Yes, or you could save some money and just buy the Firecrest 303 and switch between gravel and road tires when you change surfaces. Or, if you’ve got enough clearance in your bike and you never ride more than Class I gravel (ie., mostly dirt roads), you could use 32mm road tires for both surfaces.

          • Thanks Steve! I’ll guess switching the tires will be the way to go. Using my gravelbike for all surfaces, I reckon the Zipp Firecrest 303 wil serve me well 🙂
