Optimized Bike Bottom Bracket for MTB Riders

The new SRAM DUB bottom bracket series has a straightforward purpose: to connect your crankarms and ensure the smooth, long-lasting transfer of power to your drivetrain. To achieve this singular focus, SRAM has engineered the DUB spindle to be the unifying component across all bottom bracket standards. This one oversized spindle offers better crankarm compatibility, enhanced protection from the elements, and longer-lasting performance.

The core of DUB technology lies in the relationship between the bottom bracket spindle and bearing, where stiffness meets durability. SRAM has taken a comprehensive approach, simplifying the integration between the chainring, crank, spindle, and bottom bracket for optimized drivetrain performance.

Note that PressFit 30 DH bottom brackets require the use of a crankset with the "DUB DH BSA/ PF30/PF" markings on the spindle. Specialized tools and supplies are needed for the installation of SRAM components, so it is recommended to have a qualified bicycle mechanic handle the installation.

SRAM DUB bottom brackets feature the following specifications and features: - Crank-BB interface: DUB - Bearing type: Standard - Spindle diameter: DUB - Cup material: Aluminum - One oversized spindle to work across every bottom bracket standard - Greater bearing durability - Easy installation - PressFit cups for lighter weight - ISO 4210 compliant

SRAM's relentless pursuit of excellence is driven by a passion for cycling and a desire to empower cyclists. The company was founded in 1987 with the introduction of the Grip Shift (or twist shift) shifter for road bikes, and it quickly expanded its product range for mountain bikes.

SRAM fundamentally believes that bicycles improve the environment, ease traffic congestion, reduce transportation costs, and enhance health by reducing obesity. Cyclists are a passionate user group that support and enhance the areas in which they ride, and SRAM's products promote sustainability by enabling people to transport themselves and their families in an environmentally friendly and cost-effective manner.

Beyond its product offerings, SRAM is committed to improving its business practices to increase its positive impact on employees, communities, and the planet. The company's purpose statement is "We believe in the power of bicycles and expanding the potential of cycling. We create and manufacture components that inspire cyclists."
