The SRAM DUB bottom bracket series has one simple job: to connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow for this single focus, we have designed 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. The relationship between the bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it beyond conventional thinking and simplified everything—better integrating the relationship between chainring, crank, spindle and bottom bracket. It is this approach to developing a complete system that equates to better drivetrain performance.
