The CeramicSpeed BB Alpha Bottom Bracket for BBright SRAM Dub Road precisely pairs a 28.99 mm SRAM Dub crankset with a press-fit 46 mm asymmetric, 79 mm-wide BBright shell. This creates a secure, efficient fit ideal for modern performance road bikes.

Hand-Built Bearings for Maximum Efficiency: BB Alpha features hardened stainless-steel races hand-built with Grade 3 Silicon Nitride ceramic balls. This combination delivers ultra-low friction and long-lasting power transfer, engineered to outperform conventional bottom brackets.

Superior Moisture Protection and Durability: Custom seals and precision dust covers provide up to 500% better moisture resistance than standard designs. This enhanced shielding protects bearings from water, grit and corrosion, maintaining a smoother ride in all conditions.

Lightweight Design With Easy Installation: A simplified spacer tube and lighter cups reduce weight by 10% versus earlier CeramicSpeed models. The refined construction ensures faster installation while preserving stiffness, responsiveness and drivetrain stability.

Every BB Alpha bottom bracket comes with a lifetime warranty, guaranteeing reliable performance mile after mile.
