The new SRAM DUB™ bottom bracket series has a simple job—connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. 

To allow that singular focus, we’ve engineered the DUB™ spindle to be the one true unifying component. 

One oversized spindle to work across every bottom bracket standard. 

For better crankarm compatibility. 

For better protection from the elements. 

For longer-lasting performance. 

To be stronger, smoother, simpler. 

Now, back to the ride.
