Easton EC90 SL Carbon Crank Arms - 172mm

It is no coincidence that the Easton EC90 SL looks like the ultra-light Race Face Next SL mountain bike crank. Thanks to a lively exchange of technology between the sister companies, Easton was able to take the best features of the Next SL and integrate them into a high-end crank system for racing bikes, gravel and cyclocross.

The basis of the crank system is the hollow carbon crank arms, which not only impress with their design and low weight, but also offer enormous rigidity. To further reduce the weight, the 30 millimeter thick crankshaft is made of aluminum and can be mounted on frames with BSA threads as well as with PressFit standard. Thanks to this design, the EC90 SL weighs just 357 grams (crank arms and crankshaft), making it one of the lightest cranks on the market.

The highlight of the crank system, however, is the Cinch system adapted by Race Face. This modular system allows the crank to be adapted to the respective application in no time at all. The right crank arm can be removed using an integrated puller with a hexagonal key and the chainring can be replaced with a standard bottom bracket key for cartridge bearings or replaced with a double spider. The crankshaft and the left crank arm can remain in the frame.
