Easton EC90 SL Crank Arms

The EC90 SL 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.

Terrific crankset!

Familiarity:
I've used it several times

I installed this crankset, BB, and double chainring on my road bike to replace the prior generation EC90 model that experienced a spindle failure after 7+ years. This version is much better built, with a far beefier spindle and nicer finish than the prior version. After a dozen rides or so, my assessment is that these are quite stiff, smooth, and the understated graphics look great on a carbon frame. I?ve been keeping my eye on the preload, which has not (yet) needed any adjustment or tweaking. However, I forgot to keep my eye on the chainring bolts, and they all came lose after 100 miles or so. Not a big issue, but my daily ride tools did not?until now?include a T30 wrench. Only knock is that the proprietary spider and bolt config is making it difficult, if not impossible, to find (Lighter) chainring options for the 2x. Overall, this is a great crankset and I?m very happy with the weight, stiffness, ring options, and graphics. Highly recommend!
