SRAM Crank XX1 Eagle Fat Bike 5" DUB 12s 175 w Direct Mount 30t X-SYNC 2 Chainri

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. - Speeds: 11/12 - BB Compatibility: DUB BSA MTB 100, DUB PF MTB 121, DUB BSA73,DUB PF89.5,DUB PF92,DUB PF30 MTB73,DUB BB30 MTB73 - Chainring Size: 30, 34 - Crank arm length: 170mm, 175mm - Chainline: 49.0mm, 52.0mm, 66.5mm, 76.5mm - BB Spindle Interface: DUB - Chainring material: Aluminum - Guard: No Guard - Bolt Circle Diameter (BCD): Direct Mount (DM) - Crank arm material: Carbon - Color (Crank arm): Black, Gold - Weight (g): 433
