ethirteen XCX Race Mountain Carbon Cranks Info
XCX Race Mountain Carbon Cranks are e*thirteen’s lightest production crankset to date, built for riders who demand maximum efficiency on climbs and rapid acceleration out of corners. Developed using decades of World Cup race experience, these cranks deliver elite-level performance in a remarkably low-weight package, making them ideal for modern XC and lightweight trail builds.
At the core of the XCX Race Mountain Carbon Cranks is a patented carbon construction that trims every unnecessary gram while maintaining the stiffness required for hard efforts and technical riding. Weighing under 360 grams without a chainring and under 400 grams with one installed, the cranks feel instantly responsive under power and help keep total bike weight in check.
A robust 30mm spindle provides an excellent stiffness-to-weight ratio, while the integrated APS preload adjuster allows for precise bearing setup without additional tools. The included self-extracting system simplifies service and removal, making maintenance quick and frustration-free for riders who do their own wrenching.
Designed for modular compatibility, the XCX Race Mountain Carbon Cranks are sold without a bottom bracket or chainring, allowing riders to tailor their setup to specific frame standards and drivetrain preferences.
