True competitors are always looking for a performance advantage—a relentless pursuit of equipment that is lighter, stiffer and stronger. To create the best drivetrain possible, SRAM started with a completely reengineered crankset design. SRAM's XX1 Eagle crankset is the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with SRAM's proprietary CARBON TUNED lay-up, allows us to build a lightweight and ultra-energy-efficient crankset perfectly suited for the high-wattage output and smooth style of cross country riding and racing. Teamed up with their Eagle direct mount chainring, and as an integral part of the Eagle drivetrain, the XX1 Eagle crankset puts more focused power into every ride.
