If you have a Race Face Cinch crankset and are looking to run one of the new Shimano XTR, XT, or SLX drivetrains, look no further than Wolf Tooth's Race Face Cinch Chainring for Shimano 12-Speed. The Shimano Hyperglide 12-speed chains use a proprietary design that operates a bit differently than traditional chains, so they require a special chainring to work properly. Considering that Wolf Tooth has a long history of being problem solvers, they took the time to understand how the system works and designed a completely new tooth profile that provides optimal chain retention and durability. Now you can enjoy the quiet and smooth performance of the HG drivetrain combined with the legendary chain retention of Wolf Tooth chainrings.
