The MRP Wave Ring Cinch Direct Mount goes beyond the narrow-wide concept with its innovative Wave teeth. This patented tooth pattern not only retains optimal chain tension with modern 1x set-ups, but it's much better at shedding muck and debris in the muddiest conditions imaginable. Another bonus, it reduces overall friction for greater longevity of this chain ring. It's made to pair with the Race Face Cinch system, making it all the more future-proof with its modular, direct-mount design. It's available in a wide variety of sizes for customizing your gearing to the local trails at hand.
