DUB BB386 Bottom Bracket

The SRAM DUB BB386 Bottom Bracket is a high-performance interface designed to bridge the gap between SRAM’s universal DUB crank spindle and the BB386EVO frame standard. Part of the "Team" series, this unit focuses on lightweight construction and superior environmental sealing to ensure a smooth, long-lasting application of power.

• Durable Bearing Technology: This model is equipped with high-quality stainless steel sealed cartridge bearings. Unlike standard steel, the stainless construction offers significantly better resistance to corrosion from road salt, moisture, and frequent bike washing, extending the service life of the unit.

• Advanced Gutter Seal System: Utilizing SRAM’s Gutter Seal Technology, the bottom bracket features a specialized seal design that drastically improves protection against the elements while reducing seal drag for a silkier pedaling feel.

• Integrated Adjustability: The system includes an integrated adjuster that allows for precise fine-tuning of bearing preload. This ensures a perfect fit that eliminates lateral play and reduces the likelihood of developing creaks over time.

• Streamlined Compatibility: Engineered for an 86mm shell width and a 46mm inner diameter (BB386EVO), this bottom bracket allows riders to run any SRAM DUB (28.99mm) crankset without needing complex adapters or spacers.
