Sram Dub BSA Bottom Bracket - 68-73mm

The SRAM DUB bottom bracket series has a simple task: to connect the crank arms and protect the smooth, lasting transfer of power to the drivetrain. To enable that single focus, we designed the DUB spindle as the one true unifying component. An oversized spindle to work across all bottom bracket specifications. For better crank arm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to riding.

• An oversized spindle to work across all bottom bracket specifications

• Gutter Seal Technology™ seals out the elements

• Significantly lighter than the GXP® system

• Sealed cartridge bearings available in both stainless steel and ceramic

Specifications

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.
