Sram Dub T47 Road Bottom Bracket - 77mm

The bottom bracket series Sram DUB has a simple task: connect the crank arms and ensure smooth, lasting power delivery to the drivetrain. To achieve this single goal, we designed the DUB spindle to be the true unifying component. An oversized spindle that works with all bottom bracket standards. For better crank arm compatibility.

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.
