Easton EC90 SL Carbon Crank Arms

The EC90 SL crank utilises 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, although 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. Narrow-Wide chainring design has revolutionized the mountain bike world, effectively eliminating dropped chains and chain guides. 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.
