The WTB Raddler TCS 700c Gravel tire is an excellent choice for loose terrain where traction takes priority but efficiency is never far behind. Lean it over take the inside line brake late and stay pinned with the Raddler. Fast Rolling Center The tightly spaced and consistent central tread pattern reduces the rolling resistance while still being able to dig into any terrain. Improving your traction out of the saddle has never been easier. Center and intermediate knows are slightly taller than those on the Riddler increasing the tire’s lifespan without affecting rolling resistance. Toothy Side Knobs Only brake when you have to. The side knobs allow you to keep speed in the corners fully committed to the lean. The long toothy side knobs are consistently digging for action ensuring you have ultimate control through all corners of your favorite gravel descent. TCS Tubeless. Black or Tan Sidewals Choose the style you want with the most reliable tubeless system available.
