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 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. 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.

"The EC90SL rings and crank and Easton PF30 bottom bracket performed flawlessly during our test—responsive and durable with great chain retention." - Peleton Magazine
"...including bombing down stutter bump laden roads, the chain stayed on the ring. Considering there’s no clutch on the Ultegra derailleur, I’d say they work. Everything installed quickly and easily, too, which is always nice." - BikeRumor.com
"There’s no question about it. The EC90 SL is a lightweight, stiff crankset offering that should please serious cyclocross racers.... Many cyclocross racers will spend $2k on a race day set of wheels and tires that saves 200g or less. Rolling resistance and rotating weight discussions aside, the Easton EC90 SL crank could save the same amount of weight (perhaps even more if you’re converting from a two chainring drivetrain) for less money, but you’ll enjoy the benefits on all your rides—not just race days." - CXmagazine.com
