SRAM Dub BSA MTB Cannondale Ai Bottom Bracket

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.

Technology

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets
durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the
relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete
system that equals better drivetrain performance.
