Reliability meets simplicity—running smoothly day-in and day-out. The 350 hub was developed according to the credo: Reliability meets simplicity. The simultaneous engagement of the ratchets and the resulting large engagement area provide reliability. The plugged construction allows easy maintenance without the need for tools. Adaptation to different axle standards or modification of the engagement angle is also possible with just a few manual steps.

The number to count on—240 with Ratchet EXP. The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement (which reduces wear), and a smaller number of parts not only makes maintenance easier, but also reduces weight.
