SRAM XX1 Eagle LUNAR DUB 1×12-speed Boost Crankset with 34T Chainring – 175mm

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 deliver simplicity, compatibility, and durability.
