Building of a strong shifting ring technology platform Easton went through seven rounds of revisions and refinement with the help of rigorous lab testing and on bike field and race testing with Silber Pro Cycling.

The final product is a thing of beauty. Heavily machined for weight savings and excellent stiffness, the Easton shift rings have excellent shifting performance thanks to extensive optimized shift ramps and pins. Utilizing the versatility of the CINCH system, Easton offers spiders with a 45mm chainline optimized modern road bike hub spacing. The EC90 SL crankset is your Easton Advantage.
