The new SRAM DUB series bottom bracket takes the simple job of connecting your cranks and protecting the long-lasting, smooth application of power to your drivetrain. To allow for singular focus, we designed the DUB spindle to be the only true unifying component. An oversized spindle to work through every bottom bracket standard. For better connecting rod compatibility. For better protection against the elements. For longer lasting performance. To be stronger, softer, simpler. Now, back to the race.
