Technologies

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

DUB™
The forward-thinking and backward-compatible DUB™ BB/Crank technology is the unstoppable workhorse. Designed for the most demanding professionals. And for riders who set it and forget it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without compromises to fit all frames. Yet it opens the door to the lightest crank spindle in the world. It’s a new approach that embraces the old. And it was about time.

After extensive research, SRAM unified the diameter of bike drive shafts and internal bearings to 28.99mm starting in 2018. The new DUB (Durable Unifying Bottom Bracket) bearing technology sets new standards from now on.
