SRAM DUB BB30 73mm (55mm Chainline)
The SRAM DUB BB30 bottom bracket presses into a 73mm BB30 shell and carries steel bearings for SRAM's 28.99mm DUB spindle, built for cranks on a 55mm chainline. It is the correct bottom bracket for pairing a DUB mountain crankset in that wider chainline with a BB30 frame.
