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 we started with a completely reengineered crankset. design Our all-new XX1 Eagle� crankset is the lightest stiffest and strongest on the market. A special hollow internal architecture combined with our 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 a new Eagle� direct mount chainring and as an integral part of the Eagle� drivetrain the new XX1 Eagle� crankset puts more focused power into every ride.
