SRAM XX1 Eagle Carbon Boost Crankset

True competitors are always looking for a performance advantage — a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, SRAM re-examined and re-engineered their crankset design. Our all-new XX1 Eagle CARBON TUNED crankset is SRAM’S lightest, stiffest and strongest to date. DUB technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability. DUB-powered cranksets deliver simplicity, compatibility and durability.
