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