The new SRAM DUB bottom bracket series has a very simple task: to connect the crank arms while ensuring a durable power transfer to the drivetrain. For this specific requirement, we designed the DUB crankshaft: a single oversized shaft that works with all bottom bracket standards. For better crank compatibility, improved protection against the elements, and long-lasting performance - stable, smooth, and easy. And now, back on the bike!
