The EC90 SL crank features RaceFace Cinch technology, allowing for direct mounting of 1x chainrings and 2x spiders, as well as industry-leading versatility. The increasingly popular 1x setups offer many advantages such as weight savings and simplicity. Their biggest limitation is adaptability. The ability of a cyclocross rider to tackle a course and then effortlessly switch the chainrings to their preferred setting is a crucial necessity that has been overlooked until now. The chainring has a narrow/wide tooth profile. Easton refines the design for larger chainring applications with improved chain retention while reducing noise and friction. Finally, Easton is launching a new line of low-friction bottom brackets to complete the EC90 SL crankset package. BB sold separately.
