Easton EC90 SL Carbon Road Bike Crankset 170mm Lightweight

Designed for road racers and cyclocross athletes seeking cutting-edge performance without compromise, the Easton EC90 SL Crankset redefines versatility through its groundbreaking CINCH Direct Mount System. This innovative platform empowers riders to configure their drivetrain precisely—whether opting for sleek single-ring setups ideal for gravel adventures or traditional double-chainring setups favored by road purists—all while maintaining exceptional chain retention to tackle technical descents or off-road obstacles with confidence.

Crafted from hollow carbon fiber arms paired with a high-grade aluminum spindle interface, this crankset balances featherlight weight (352g) with stiffness that maximizes power transfer during sprints or climbs. Its optimized bearing system reduces friction noise during long rides while enhancing durability under heavy loads—a must-have feature for endurance athletes or competitive cyclists pushing limits on pavement or dirt.

Engineered to adapt to diverse setups, the EC90 SL supports 10- and 11-speed drivetrains across multiple hub standards (including 130mm road hubs or disc brake systems like 135/142mm). It accommodates frames with varying chainstay lengths (>415mm or <415mm) when paired with compatible hubs—making it a go-to choice for custom builds or riders upgrading existing setups.

While sold without chainrings or spiders (requiring separate purchase), its modular design allows easy upgrades using an ISIS 20-tooth tool—ideal for those evolving from casual riding to competitive events. The RaceFace/Easton spindle interface ensures secure pedal attachment without excess bulk, prioritizing both performance and aesthetics.

Perfect for riders balancing speed demands of road racing with cyclocross’s unpredictable terrain, this crankset outperforms rigid competitors by blending lightweight agility with rugged reliability—making it an essential upgrade for serious cyclists chasing podium finishes or exploring mixed-surface trails.
