XX1 Eagle DUB Crankset

True competitors are always looking for a performance advantage — a relentless pursuit of lighter, stiffer, stronger, and more durable equipment. 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.
