Sram Xx1 Eagle Dub Crankset Grey

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 bsa73dub pf89.5dub pf92dub pf30 mtb73dub 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
