The Race Face Era Cinch Direct Mount Chainring brings chainring evolution to your drivetrain with a clever three-part design that's playing the long game. By bonding stainless steel teeth to a 7075 aluminum CINCH interface with a carbon fiber spider, this ring delivers aluminum-like weight that won't have your bike hitting the gym, but with steel-worthy durability that'll be around for the long haul. With a lifespan five times longer than typical alloy rings, the Era Chainring is one of the best investments you can make in your rides.
