Race Face Direct Mount Cinch Narrow Wide Chainring 2018 Race Faces new Direct Mount Single ring. Designed and machined in our Vancouver, BC facility, tested on the North Shore and in the Whistler Bike Park. SRAM Direct Mount rings fit SRAM GXP cranks with the removable spider. Replaces your existing chainring and spider which is attached via 3 bolts on the back of the spider. Remove spider and simply use these same 3 bolts to re-attach the Race Face DM ring. Race Face Direct Mount rings deliver substantial weight saving compared to a standard SRAM chainring and spider combo. And with added benefit of Narrow/Wide tooth configuration. Compatible with SRAM X9, X0, XX1 and Truvativ AKA cranks. Also compatible with some OE cranks, including the SRAM S1400, S2200 and S2210. GXP models only. Newer S1400 (or X7) cranksets will also work with RF DM rings.
