The SRAM DUB bottom bracket series has a simple task: to connect the crankarms and protect the smooth, lasting application of power to the drivetrain. To enable that singular focus, we designed the DUB spindle to be the one true unifying component. An oversized spindle to work across all bottom bracket standards. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, let's get back to riding.
- An oversized spindle designed to work with all bottom bracket standards
- Gutter Seal Technology™ seals out the elements
- Significantly lighter than the GXP® system
- Sealed cartridge bearings available in both stainless steel and ceramic
