SRAM DUB English/BSA Bottom Bracket

The SRAM DUB English/BSA bottom bracket is designed for MTB frames with a 73 mm shell in the English/BSA standard. The part uses the DUB spindle, with an oversized spindle that works with all bottom bracket standards, and the Cannondale AI MTB version is specified for Cannondale bikes with the AI system.

Gutter Seal Technology improves sealing against external elements, while sealed cartridge bearings help durability over time. It is noticeably lighter than the GXP system and complies with the ISO 4210 standard. Before buying, check that your frame shell is 73 mm wide and uses the English/BSA standard.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
