The all-new and innovative adapter system is ideal for attaching bags like the waterproof Fork-Pack to the fork of your bike. Weighing just 275 grams including the adapter the Fork-Pack offers approximately 3.2 liters of additional storage space for bike packing. With the help of the QLS adapter this ultra-light bag with roll closure can be mounted on forks with eyelets or cage mounts intended for this purpose as well as on forks without cage mounts as long as the fork blades sport a constant diameter of 30 mm to 42 mm. QLS bags are primarily designed for attachment to the fork but can be attached to all vertical tubes using the accessories supplied.
