SRAM DUB Press Fit Bottom Bracket – Road (86.5mm)

Pro-Level Efficiency: The Powerhouse of Your Road Drivetrain

The SRAM DUB Press Fit Road bottom bracket (Model A1) is the essential interface for modern SRAM road drivetrains (Red, Force, Rival, and Apex). Engineered for frames with a 41mm shell diameter and 86.5mm width, this unit utilizes DUB (Durable Unified Bottom Bracket) technology. By standardizing the spindle to 28.99mm, SRAM has created a system that offers the stiffness of a large-diameter axle with the longevity and sealing typically found in smaller systems. It is the gold standard for smooth, reliable power transfer on the tarmac.

Key Features

• High-Grade Steel Bearings: Precision-engineered steel balls provide minimal rolling resistance and maximum durability under high-cadence road riding.

• Gutter Seal™ Technology: A sophisticated seal design that significantly reduces friction while keeping contaminants like road spray and dust out of the bearing races.

• Precision Composite Cups: The high-strength nylon cups are designed for a perfect interference fit within the frame, reducing the likelihood of the "creaking" often associated with Press Fit systems.

• DUB™ Universal Standard: Simplifies maintenance and allows the same DUB Road crankset to be used across different frame standards with the appropriate DUB BB.

FAQ - Frequently Asked Questions

• Is this the correct BB for my SRAM Force AXS groupset? Yes. This is the official and most common bottom bracket for the entire SRAM 12-speed Road AXS range when using a Press Fit frame.

• Can I use this on a Gravel bike? If your gravel frame uses the Road 86.5mm shell standard (and you are using a Road DUB crankset), then yes. Always check your frame manufacturer's shell width.

• How do I install it? Professional installation with a 41mm Bearing Press Tool is highly recommended to ensure the cups are perfectly aligned, which prevents premature bearing wear and noise.
