SRAM DUB PressFit30 Bottom Bracket

The 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, SRAM engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket specification. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.MODEL ID: BB-DUB-PF30-A1 FEATURES One oversized spindle to work across every bottom bracket specification. Easy installation PressFit cups for lighter weight Sealed cartridge bearings available in both stainless and ceramic versions TECHNOLOGY DUB The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM 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.
