SRAM DUB PressFit Bottom Bracket

The SRAM DUB crankset series has one simple job: to connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, we’ve engineered the DUB spindle to be the one true unifying component. An oversized spindle to work across every bottom bracket specification. For a better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.

FEATURES

• One oversized spindle to work across every bottom bracket specification
• Significantly lighter than GXP system
• Easier installation by allowing you to press the bearing cups into the frame
• Sealed cartridge bearings available in stainless steel and ceramic versions

TECHNOLOGY

DUB™ The forward-thinking and backward-compatible DUB™ BB/Crank technology is the unrestrained workhorse. Designed for the most demanding pro riders. And the riders who set it and forget it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet, it opens the door to a new crank spindle for the lightest crankset in the world of all time. It’s a new approach that embraces the old. And it’s high time. After extensive research, Sram unifies the crank and inner bearing diameter for bicycles to 28.99mm from 2018. The new DUB (Durable Unifying Bottom Bracket) bearing technology sets new standards from now on.
