DT Swiss Ratchet System

This hub uses the DT Swiss Ratchet System with the default Ratchet 36 (36 teeth, 10 degrees of engagement). Because both ratchet rings engage simultaneously, the system is exceptionally robust, and it can be upgraded tool-free to the Ratchet 54 (6.7 degrees) for quicker pickup. Servicing needs no special tools.

Compatibility & fit

Rear position, QR 130mm road rear (5/130) spacing, 28 hole, rim brake (non-disc). Shimano 11-speed road HG freehub takes Shimano/SRAM 11-speed road HG cassettes (and compatible lower-speed HG cassettes). J-bend (Classic) spokes.
