The EC90 SL crank utilizes the RaceFace 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 riders ability to ride a course, then effortlessly change chainrings to their preferred setup is a major necessity that has, until now, been overlooked. The chainring has a narrow/wide tooth profile. Easton refines the design for larger ring applications with improved chain retention while reducing running noise and friction. Finally, Easton launches a new line of low friction Bottom Brackets to complete the EC90 SL Crank package.
