The EC90 crank utilizes the Race Face CINCH technology which allows for direct mount 1x rings as well as direct mount 2x spiders, and industry leading versatility. 

Increasingly popular 1x setups have many advantages including weight and simplicity. Their major limitation is 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.

Arms come assembled with spindle. Rings and BB sold separately.
