Race Face Era Cinch Chainring

This chainring is specifically designed for the Race Face Cinch direct mount system. It will not fit cranksets that use a standard bolt-pattern or other proprietary direct mount interfaces.

The hybrid construction is about balancing durability and weight. The carbon fiber spider keeps the weight low, the aluminum interface ensures a stiff, secure connection to the crank, and the stainless steel teeth provide significantly better wear resistance than standard aluminum rings.

No, this chainring is optimized specifically for Shimano 12-speed HG+ chains. Using it with an 11-speed drivetrain will likely result in poor shifting performance and premature wear.

The 55mm chainline is designed to accommodate modern mountain bike frames with wider 'Boost' spacing. It ensures proper chain alignment and reduces cross-chaining stress when you are in the larger cogs of your cassette.

At 83 grams, this chainring is exceptionally light for its durability class. While weight savings vary by model, the primary advantage here is the longevity of the stainless steel teeth, which allows you to run a lighter setup without replacing the ring as often.
