The SRAM DUB bottom bracket connects crankarms to your frame and protects the drivetrain. With gutter seal technology, the bottom bracket's bearings are protected, lightweight, and long-lasting.
SRAM engineered the oversized DUB spindle to work across every bottom bracket standard, simplifying crankarm compatibility.
This bottom bracket is a BB30 68/73, meaning it's compatible with both 68mm and 73mm bottom bracket sizes.
