Recently, Easton expended its bike component offering with the Easton EC90 SL crankset. The set has hollow carbon arms and comes in 1-by and 2-by configurations.

For EC90 SL system, Easton drew upon expertise at Race Face, specifically the Next SL. The mountain bike crankset is built around Cinch, a method of attaching a spider or direct-mount chainring easily.

The Easton EC90 SL seems best suited for the cyclocross racer running 1-by. You simply need to undo the crank bolt and Cinch lock ring to swap a chainring. If your CX race is hilly, you can opt for a 38 tooth. If you run 1-by on the road or on flat gravel sections (or you can lay down crazy high watts), there’s a 50-tooth direct-mount ring on the high end. The 40-, 42-, 44-, 46- and 48-tooth rings round out the direct-mount options. You can even convert from a 1-by to 2-by setup and back. The rings have a narrow/wide profile to keeps things running smoothly and to hold each chain well.

As for compatibility, Easton has various standards covered including BB86, BSA, PF30, BB30, BRight, 386EVO and OSBB. The company is also launching its own line of low-friction bottom brackets to complement the crankset.

If you want to go 2-by, your options include 53/39-tooth, 52/36-tooth and 50/34-tooth. Crank lengths run from 170, 172.5 and 175 mm.

Easton says a crankset with 172.5-mm crankarms and 52/36-tooth rings without bottom bracket weights 590 g. For a set with 172.5-mm crankarms and a 40-tooth ring with no bottom bracket, the claimed weight is 442 g.

The company says the 1-by crankset, single, direct-mount rings and Easton bottom brackets will be available in early August. The 2-by setups are set to come out in the fall.
