Sram Dub Bsa Mtb/Road 68/73 Medium Bed

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.

COMPATIBLE WITH ROAD AND MTB DUB CRANKSHAFTS
