SRAM DUB Road Bottom Bracket | BB30 73 mm (73-A) - Ceramic

The SRAM DUB™ (Durable Unified Bottom Bracket) bearing series is created with one primary goal – to connect your crankarms and ensure smooth, long-lasting power transfer to your bike's drivetrain. To achieve this goal, SRAM developed the DUB™ spindle as the universal piece that fits all bottom bracket standards. This means one oversized spindle compatible with every bottom bracket standard. It leads to better crankarm compatibility, protection against dirt, dust, and water, longer-lasting performance, and a stronger, smoother, simpler construction.

Key Features:

• One oversized spindle to work across every bottom bracket specification.
• Easy installation
• Outboard and inboard cup options to support your bike’s spec.
• Ceramic Bearings: Opting for ceramic bearings, you get a lower friction coefficient and a longer service life, allowing the bike to operate more smoothly and efficiently.
• Size: 46 x 73 mm (73-A)
