SRAM DUB BB30 bottom bracket
The new SRAM bottom bracket series DUB ™ has a very simple task: to connect the crank arms to one another and to ensure a long-lasting power transmission into the drive. SRAM designed the DUB crankshaft for this specific requirement: a single oversized shaft that works with all bottom bracket standards. For better crank compatibility, better protection against the elements and long-lasting performance - more stable, smoother, easier. And now back on the bike!
