Sram Dub T47 Road Bottom Bracket - 77mm

The Sram DUB bottom bracket series has a simple task: to connect the crankarms and protect the smooth and lasting transfer of power to the drivetrain. To achieve this unique goal, we designed the DUB spindle to be the true unifying component. An oversized spindle that works with all bottom bracket standards. For better compatibility with crankarms. For better protection against the elements. For longer-lasting performance. To be stronger, smoother, simpler.
