Sram DUB BSA 68/73mm | Bottom Bracket

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.

• DUB™ technology features a better engineered bottom bracket and a new spindle design for a more uniform approach to bottom bracket fitment, better sealing against contamination, and a new measure of durability
• Gutter seal technology
• Stainless steel sealed cartridge bearings
• For use with all SRAM DUB cranks and 68/73mm BSA threaded shells
