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 neater approach to bottom bracket hardware, better sealing against contamination, and forward and reverse compatibility. Now everyone can benefit from a new measure of stamina.

With DUB technology, there is now a single crankset with a 28.99mm spindle. In order to attach the DUB crankset you want to use on your bike to your bike with a different middle bed standard, you only need to buy a DUB middle bed that is compatible with your middle bed.

Now you can attach your DUB technology crankset to your bike with different center bearing standards, simply by changing your center bearing.

COMPATIBLE WITH ROAD AND MTB DUB CHANNELS
