Sram Dub Bb30 Mtb/Road 73 Medium Bed

SRAM bottom bracket DUB | BB30 73

Right bottom bracket for the new generation of SRAM DUB cranks for mountain bike frames with BB30 bottom bracket shells. The DUB bearings feature an improved seal to ensure the crank runs smoothly for even longer.

DUB™ technology features a better designed bottom bracket and a new spindle design. Together, these provide a more streamlined approach to bottom bracket fitment, better sealing against contamination, and forward and reverse compatibility. Now everyone can benefit from a new measure of durability.

With DUB technology, there is now a single crankset with a 28.99mm shaft as standard. In order to install the DUB crankset you want to use on your bike to your bike with a different center bearing standard, you only need to buy a DUB center bearing that is compatible with your center bearing.

Now you can install your crankset with DUB technology on your bike with different center bearing standards by simply changing the center bearing.
