Easton Cinch Chainring

This chainring is specifically optimized for Shimano HYPERGLIDE+ 12-speed chains. It is designed to work seamlessly with that specific tooth profile to ensure smooth shifting and reliable retention.

It is designed exclusively for Easton's EC90 SL and EA90 cranksets using the CINCH direct-mount interface. It will not fit cranksets from other brands or non-CINCH Easton models.

The direct-mount interface makes swapping rings straightforward. You will need the appropriate bottom bracket tool to remove the lockring, but once that is off, the chainring slides on and off quickly without needing to remove the entire crankset.

No, an external chain guide is not required. The tooth profile is engineered for high-performance chain retention, so you can ride confidently on rough gravel or road surfaces without worrying about dropped chains.

The specialized CNC shaping around the teeth helps shed mud and debris more effectively than standard designs. This prevents buildup that can cause chain suck or premature wear, keeping your drivetrain running smoothly in messy, wet conditions.
