Enjoy Every Ride With The EA90 Aluminum Chainring

Whether you prefer long stretches of the open road or are more of a rough gravel type, your bike could use an upgrade. The Easton EA90 SL Direct Mount Chainring - Flattop uses a narrow/wide design that is specifically tailored to cyclists who like to ride hard and enjoy every minute of it.

A construction of EA90 SL Alloy provides all the durability you need to make switching gears a breeze. The individual tooth profile has moved from the traditional symmetrical shape to a more directional specific design. This delivers a positive chain roller engagement which helps with chain retention, as that is critical to preventing the chain from slipping or bouncing while conquering rough terrain.

The Easton EA90 SL Direct Mount Chainring is specifically tailored to road, gravel, and cx applications. This one-of-a-kind ring is optimized for Flattop 12 Speed chains, though it is also compatible with 11-speed chains as well. Take on the next adventure with a sturdy chainring that's got your back — no matter what.

  • Cinch System Compatible
