The SRAM DUB BSA bottom bracket brings SRAM's oversized DUB spindle system to a threaded 68mm BSA shell, a common standard on many road frames. Aluminum cups house the bearings securely, creating a solid interface between frame and crankset while keeping installation straightforward for home mechanics and shop technicians alike.
Gutter Seal Technology on the Standard version helps keep water and grit away from the sealed cartridge bearings, supporting smooth rotation over time. Built for SRAM Road Wide cranksets such as the Force Wide DUB crank, this bottom bracket pairs a 34.8mm bearing housing with a 28.99mm crank shaft interface for compatibility across SRAM's wide road lineup.
