SRAM XX1 Eagle Boost 148 DUB 12-Speed Chainset With Direct Mount 34T X-Sync 2 Chainring (BB Not Included)

Lighter, Stiffer, Stronger
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, we re-examined and re-engineered our crankset design. Our all-new XX1 Eagle CARBON TUNED crankset is our 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 mean simplicity, compatibility and durability.
