With their new DUB cranksets and bottom bracket standards, SRAM have upped their game, with the two products combining to create a lighter, stiffer and more durable system. SRAM's DUB PF30 Bottom Bracket fits in your standard PF30 bottom shell and provides a stiffer and more durable bottom bracket compared to the competition and SRAM's own GXP design. 

By using a 28.99mm axle, the DUB bottom bracket offers bigger bearings than bottom brackets used for 30mm crank axles, improving durability and stiffness, as well as being lighter. The DUB system replaces SRAM's previous GXP and BB30 crank and bottom bracket systems to provide improved durability, better compatibility and a stiffer, stronger and lighter product. DUB cranks can be used with any existing bottom bracket standard when used with the appropriate DUB bottom bracket. Performance benefits aside, it also means your crank is future proofed in case you happen to swap your frame. Easy to install and highly durable, SRAM's DUB PF30 Bottom Bracket sets a new standard in durability and longevity.

Customer Reviews

This bottom bracket enables you to use the newer DUB cranks when using older PF30 standard. Therefore extending the life of older bikes.

I use my MTB in all weathers, which means for the UK lots of mud and wet! So bearings will wear quicker, I managed to get a about 3yrs out of the last SRAM bottom bracket. The drive side bearing failed this time.

With the right tools, only takes about 30min to replace and easy to do.
