The TRP CR-M9050 EVO chainring is engineered for 12-speed MTB drivetrains. Designed with a 3mm Boost offset to suit modern Boost-spaced frames, it mounts via CINCH interface and pairs seamlessly with TRP EVO cranks. The 30T option suits technical terrain where lower gearing keeps the pedals turning. The sandblast finish gives a clean matte look that holds up on the trail.
