Direct power 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.
