The SRAM DUB bottom bracket series has a simple job: connect the cranks and protect the smooth and long-lasting application of power to the drivetrain. To enable that singular focus, we designed the DUB chuck to be the one true unifying component. An oversized pivot to work on all bottom bracket specifications. For better compatibility with cranks. For better protection from the elements. For longer lasting performance. To be stronger, smoother, simpler.
CHARACTERISTICS
- An oversized pivot to work on all bottom bracket specifications.
- Significantly lighter than the PFGXP system
- Easier installation by allowing you to press the bearing cups into the frame
- Sealed cartridge bearings available in both stainless steel and ceramic
Technology
DUB
The relationship between the bottom bracket pivot and the bearing is the heart of DUB technology. It's where rigidity meets durability. We've taken a step beyond conventional thinking and made everything simpler by better integrating the relationship between chainring, crank, spindle and bottom bracket. It is this approach to developing a complete system that equates to improved powertrain performance.
