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. The 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.
