DT Swiss Ratchet System

The 350 uses the DT Swiss Ratchet System, in which two face-toothed star ratchets engage across their full circumference for even load distribution and dependable power transfer. It ships with the Ratchet 36 (36 tooth, 10 degree engagement) and can be upgraded to the Ratchet 54 (6.7 degree) without tools for faster pick-up.

Designed for Boost 12/148mm rear dropouts with 28 spokes and Shimano Micro Spline 12-speed cassettes. Uses a Center Lock disc rotor. Confirm your frame spacing, driver standard and rotor interface before purchase.
