The new Easton SHI 12 SPD Gravel and Road 1x chainring brings 12 speed compatibility to the lightest and most versatile crankset on the market, the Easton EC90 SL. Via the simplicity of CINCH, riders can enjoy the expanded gear range and butter-smooth shifting of 12-speed, while conveniently swapping rings on their EC90 SL or EA90 cranks. Our optimized tooth profile offers excellent chain retention while minimizing drivetrain friction commonly experienced in 1x applications, no chain guide needed. And like all Easton chainrings, our CNC shaping below the teeth improves mud clearance from the tooth-chain interface to prevent chain drop and wear. This chainring's updated tooth profile is optimized for Shimano HYPERGLIDE 12-speed chains and is compatible with Shimano 12-speed drivetrains.
