Smoother and Lighter — Easton Crankarm And Spindle Setup

Thanks to a superior utilization of RaceFace Cinch technology, the Easton EC90 SL Crankarms allows for direct mount 1x rings as well as direct mount 2x spiders — perfect for all cyclocross riders.

Constructed with EC90 SL carbon arms and an EA90 SL spindle, this increasingly popular 1x setup is ready for action. The advantages of a setup like this are lightweight simplicity, though it falls short on adaptability. A Cyclocross rider’s ability to ride a course, then effortlessly change chainrings to their preferred setup is a major necessity that has, until now, been overlooked.

Easton refines the design for larger ring applications with improved chain retention while reducing running noise and friction. When it’s time to upgrade your setup, make sure to include the Easton EC90 SL Crankarms for a bike that runs like a pro through technical segments and tight turns.
