Product Details

Overview & Technology

SRAM DUB PF89/PF92 brings SRAM's DUB system to press-fit BB92 frames, combining a precisely engineered spindle interface with robust sealed bearings to reduce play, stop creaks and resist contamination. The DUB spindle diameter of 28.99mm provides a standardized interface for modern SRAM cranksets, improving stiffness and drivetrain consistency across models. The unit uses sealed steel bearings housed in pressed cups sized for a 41mm cup diameter and a 92mm shell width. The design emphasizes uniform fitment and long-term durability — key for riders who want reliable performance on the road or rougher gravel roads without frequent bottom bracket service.

Key Features

Precision fit and sealing: DUB technology prioritizes a uniform spindle fit and upgraded seals to keep grit and water out of the bearings. That means smoother pedaling and less maintenance over time. • DUB interface — optimized for SRAM 28.99mm spindles. • Sealed steel bearings — durable and replaceable for long life. • Press-fit cups — 41mm cup diameter sized for BB92 frames. • BB shell width — specifically built for 92mm press-fit shells. These elements work together to deliver a quiet, stiff bottom bracket that reduces drivetrain losses and is tolerant of real-world conditions like road spray and gravel muck.

Fit & Compatibility

The DUB PF89/PF92 is designed specifically for frames with a BB92 press-fit shell (92mm width) and a 41mm press-fit cup diameter. It accepts SRAM DUB crank spindles with a 28.99mm diameter — this is the standard DUB spindle size found on modern SRAM road and gravel cranksets. Not compatible with 24mm (Shimano/most older cranks), BB30 30mm spindles, or threaded BSA shells unless used with a separate adapter system. Proper installation requires press-fit tools and correct frame tolerances; we recommend checking shell faces and diameters and using a press tool to avoid frame damage.

Who It's For

This bottom bracket is ideal for road and gravel riders who run SRAM DUB cranksets and need a press-fit solution for BB92 frames. It's a great choice for those who prioritize a quiet drivetrain, low maintenance sealed bearings, and improved sealing against contamination. If you ride year-round, often ride in wet or gritty conditions, or are upgrading from older spindle standards to SRAM's DUB system, the PF89/PF92 provides a straightforward, durable upgrade with a wide compatibility across current SRAM cranklines.

Frequently Asked Questions

Will this bottom bracket work with my SRAM DUB crank?

Yes — the DUB PF89/PF92 accepts SRAM cranks that use the DUB 28.99mm spindle. Confirm your frame has a BB92 press-fit shell (92mm width) and 41mm cup diameter before ordering.

Can I install this in a threaded (BSA) frame?

No — this unit is a press-fit BB specifically for BB92 shells. Threaded BSA frames require a threaded DUB bottom bracket or the appropriate adapter; do not press-fit this unit into a threaded shell.

Are the bearings serviceable or replaceable?

The unit uses sealed steel bearings that are replaceable when they wear. Because they are sealed, regular servicing is minimal — but replacing the bearings or the complete unit when wear occurs is straightforward with the correct press tools.

What tools or prep do I need for installation?

You should use a professional press-fit bottom bracket tool to install the cups cleanly and evenly. Inspect and, if necessary, face the shell surfaces to ensure correct fitment. Use assembly paste/grease on the cups to prevent corrosion and noise.

Is this compatible with 24mm or BB30 spindles?

No — the DUB PF89/PF92 is designed for the DUB 28.99mm spindle only. 24mm (Shimano) or 30mm (BB30) cranks require different bottom bracket standards or adapters.

How durable is the DUB PF89/PF92 in wet and gravel conditions?

SRAM designed DUB BBs with improved sealing and robust steel bearings for real-world durability. While more resistant to contamination than many older press-fit BBs, longevity still depends on riding conditions and maintenance — heavy exposure to water and mud will shorten service life.

Buying Guide

When choosing a press-fit bottom bracket, first confirm your frame's shell type, width and press diameter. For the DUB PF89/PF92 that's BB92 (92mm width) with a 41mm cup diameter. Next confirm your crank's spindle: this BB accepts SRAM DUB 28.99mm spindles only. Consider your riding conditions: sealed steel bearings are a great balance of durability and serviceability for road and gravel riders. If you frequently ride in extreme mud or need the lightest possible option, compare bearing materials and service options across BB models before purchasing.
