ethirteen XCX Race Carbon Gravel Cranks Info

The ethirteen XCX Race Carbon Gravel Cranks bring World Cup racing heritage directly into the gravel world, distilling years of high-level competition into one of the lightest production carbon cranksets available today. Designed for riders who obsess over efficiency and responsiveness, these cranks deliver a remarkably low system weight—sub-360 g without a chainring and under 400 g when paired with one—making them a standout choice for elite gravel racers and fast-paced adventure riders alike.

Engineered around a stiff and lightweight 30 mm spindle, the XCX Race Carbon Cranks strike an exceptional balance between durability and acceleration. ethirteen’s patented carbon design enhances power transfer while keeping rotational mass to a minimum, helping riders maintain speed over rolling terrain and punch up steep climbs with confidence. The integrated APS preload adjuster ensures precise bearing tension, while the self-extractor system brings practical serviceability to a top-tier carbon crankset—ideal for riders who want performance without maintenance complexity.

Whether you’re lining up for a gravel race, chasing PRs, or building an ultra-light explorer, the XCX Race platform elevates every pedal stroke. Bottom bracket and chainring options are sold separately, allowing you to tailor the setup to your terrain and drivetrain preferences.
