Sram XX1 Eagle Dub 1x12 crankset



SRAM XX1 Eagle DUB 1x12 speed Boost 34T crank



The optimal entry into the world of 1x12 speed in the Boost version with the new "DUB" standard (28.99mm axle diameter) and 3mm of outermost chain line. Real competitors are always looking for a performance advantage - a relentless search for equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, we re-examined and redesigned our crankset design.

The all-new XX1 Eagle™ CARBON TUNED™ crankset is our lightest, stiffest and strongest crankset to date. SRAM DUB™ technology improves this by simplifying the relationship between the spindle and the bottom bracket and redefining the measurement of durability. Cranksets with DUB™ technology mean simplicity, compatibility and durability.

Technologies


BOOST™
With revolutionary advances in bicycle components, such as SRAM's XX1, X01 and X1 drivetrains, mountain bike designers have had almost unlimited freedom to focus solely on the performance of the bike. Every advancement requires the entire package to function flawlessly. Aggressive trail and enduro racers have increasingly enjoyed the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. That's why SRAM has developed an open standard with Boost™ compatible components for SRAM drivetrains, hubs and RockShox forks.

DUB™
Forward-thinking, backwards-compatible DUB™ BB/Crank technology is the no-holds-barred workhorse. Designed for the most demanding professionals. And for cyclists who set it and neglect it. DUB™ is compatible with all major bottom bracket standards. Offering a better hold than ever, without having to make compromises to fit all frames. Yet it opens the door to a new spindle for the world's lightest crankset. It's a new approach that embraces the old. And it was time.

After extensive research, Sram unifies the diameter of bicycle crankshafts and internal bearings to 28.99mm from 2018. The new DUB (Durable Unifying Bottom Bracket) bearing technology sets new standards from now on.
