This fat bike chainset features a stiff carbon crankarm construction, which means that you'll enjoy its quick and smooth operation as you weave from trail to trail. SRAM has also equipped this model with an aluminium chainring, giving this model an overall superior strength to weight ratio. Its hard-wearing build also allows it to handle all the intensity that's associated with all-day epics in the mountains while ensuring maximum power transfer on every ride.

Built for Fat Bikes: 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.
