Easton EC90 SL Carbon Crankarms

Easton EC90 SL Carbon Crank Arms

Build your next road, gravel or cyclocross setup around lightweight carbon crank arms with the flexibility to choose your gearing. The Easton EC90 SL combines EC90 carbon arms with a modular CINCH interface, accepting a compatible 1x direct-mount chainring or 2x spider and chainring assembly.

Whether you’re refreshing an existing bike or assembling a custom build, the interchangeable mounting system lets you change your gearing without replacing the crank arms.

What’s included?

Will these fit my bike?

These cranks require a bottom bracket suitable for both your frame and the 30mm spindle. Chainring selection must also match your chain, drivetrain and required chainline.

Your existing bottom bracket may need replacing when changing from another crank system.
