DT Swiss 350 J-Bend Road Rear Hub Ratchet Reliability, Road Ready Road and gravel wheelbuilders who want a hub they can count on for tens of thousands of kilometers have a clear answer in the 350. The Ratchet System's 36-tooth star ratchet engages across its full face on every pedal stroke, delivering consistent power transfer without the fragility of a pawl-and-spring setup.

The 350 is offered in enough axle and freehub configurations to fit whatever frame and drivetrain you're working with.
