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.
~ One oversized spindle to work across every bottom bracket standard.
~ Significantly lighter than PFGXP system
~ Easier installation by allowing you to press the bearing cups into the frame
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.
