Sram Bottom bracket Dub BB30 R68/42 Wide

The new bottom bracket series SRAM DUB has a simple job: connect the cranks and protect the smooth and lasting application of power to your transmission. To enable that singular focus, we designed the DUB spindle to be the only true unifying component. An oversized spindle to work on all bottom bracket standards. For better crank compatibility. For better weather protection. For longer lasting performance. To be stronger, smoother, simpler. Now, back to running.

The relationship between bottom bracket pin and bearing is at the heart of DUB ™ technology. It is where rigidity meets durability. We have taken a step beyond conventional thinking and made everything easier, better integrating the relationship between crown, crank, pin and bottom bracket. It is this approach to developing a complete system that equates to better transmission performance.
