Unable to load collection availability
Description
The SRAM DUB BB30 73mm Bottom Bracket connects the cranks to the frame for smooth, durable power transfer. Built around the oversized DUB spindle, it improves compatibility across bottom bracket standards while Gutter Seal technology enhances protection against dust and moisture.
Its sealed cartridge bearings and standard design deliver smooth running and longevity for optimal efficiency with every pedal stroke. It fits BB30 shells measuring 73 mm wide and 42 mm in diameter, with a chainline compatible with Boost cranks.
Compliant with ISO 4210 and noticeably lighter than the previous GXP system, this bottom bracket is a reliable replacement part for restoring the precision of a SRAM DUB drivetrain on a BB30 mountain bike frame.
