Wolftooth Direct Mount Chainrings for Race Face Cinch Boost for Shimano 12spd Hyperglide

The new Shimano XTR XT and SLX 12spd Hyperglide+ chain works differently than other products on the market so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology. The new HG+ chain interacts with the chainring much differently than a traditional wide/narrow design. Wolf Tooth engineers spent the time to understand how the system works and design a new tooth profile that is optimized for this system.Engineered proprietary tooth profile maintains the quiet and smooth performance of the HG+ drivetrain with legendary Wolf Tooth chain retention.Prevents premature ring and chain wear that can come from non-optimized profiles.CompatibilityAny Race Face Cinchâ„¢ system crankset.Compatible with Shimano 12-speed Hyperglide+ chainsShimano 12 speed HG+ drivetrains use a 52mm Boost chainline for both 148mm Boost and 142mm standard rear hub spacing
