Product Details

Overview & Technology

SRAM DUB PF86 brings the DUB axle standard to press-fit road frames, delivering a simple, durable bottom bracket solution for 86–86.5mm shells (BB86/BB92-style). It pairs a 28.99mm DUB spindle interface with sealed steel bearings and 41mm cups to stabilize your crankset and reduce flex and wear in the bottom bracket area. The unit uses precision-pressed cups sized for a 41mm shell ID and robust sealed steel bearings that prioritize longevity and resistance to contamination. The DUB design centers the spindle and bearings for consistent chainline and reduced lateral play, while the sealed assembly helps cut drivetrain noise and lowers maintenance intervals on long rides and in wet conditions.

Key Features

Sealed steel bearings: Durable steel races and seals designed for high-mileage road use, offering predictable service intervals and good load handling under pedaling torque. DUB spindle compatibility: Optimized for SRAM DUB cranksets with a 28.99mm spindle to ensure a precise fit, smooth rotation, and reduced creak when installed correctly. Cups are sized to a 41mm shell ID and finished in black to match modern framesets.

Fit, Specs & Compatibility

Shell fitment: Intended for press-fit road shells in the 86–86.5mm width range (commonly referenced as BB86 or BB92-style press-fit). Cup diameter is 41mm — verify your frame's shell ID before purchase. The product is labeled as BB-DUB-PF-A1 with Manufacturer Part # 00.6418.025.000 and SRAM PN 380484. Compatibility notes: Use this bottom bracket with SRAM DUB crank spindles (28.99mm). It is not compatible with older 24mm or 30mm spindle standards without an adapter. Proper frame shell tolerance, bore roundness, and clean installation are important to avoid noise and premature wear.

Who It's For

This bottom bracket is aimed at road cyclists running SRAM DUB cranksets on press-fit frames who want a low-maintenance, reliable interface. It's a go-to choice for club riders, gran fondo participants, and sportive riders who value durability and smooth pedaling feel without switching to threaded conversions. If you own a frame with a BB86/BB92-style press-fit shell and want a direct-fit solution for SRAM DUB cranks — especially if you prioritize simple serviceability and proven steel bearings over lightweight ceramic options — the DUB PF86 is a practical, cost-effective upgrade or replacement.

Frequently Asked Questions

Will this fit my frame?

The DUB PF86 fits press-fit road shells with an internal diameter around 41mm and a shell width of approximately 86–86.5mm (commonly called BB86 or BB92-style). Confirm your frame's shell ID and width before ordering to ensure a correct fit.

Is it compatible with non-SRAM cranks?

This bottom bracket is designed for SRAM's DUB 28.99mm spindle. It may work with other cranksets that use the same 28.99mm DUB interface, but it is not compatible with older 24mm or 30mm spindles without specific adapters.

How do I prevent creaks with a press-fit BB?

Proper installation is critical: ensure frame bores are clean, face and ream to spec if necessary, press cups squarely with the correct tool, and apply a thin layer of bearing-grade grease or assembly paste on the cups and shell interface. Torque the crank preload correctly and recheck after initial rides.

What maintenance does this bottom bracket require?

Sealed steel bearings minimize routine upkeep; inspect for play or roughness every 6–12 months depending on conditions. Replace bearings or the entire unit if you notice grinding, excessive lateral play, or water ingress—typical service intervals depend on mileage and exposure to wet conditions.

Can I install this myself?

If you have the correct press-fit tools and experience, you can install it at home. However, many riders choose a local bike shop for a precise press and to check shell tolerances—improper installation is a common source of noise and premature wear.

How much does it weigh?

SRAM lists the shipping weight at approximately 0.225 lb (packaged). The installed unit is lightweight for a sealed steel-bearing press-fit bottom bracket while focusing on durability over shaving grams.

Buying Guide

When choosing a press-fit bottom bracket for a road bike, first verify your frame's shell standard — measure shell width and ID or consult the manufacturer's spec sheet. For SRAM DUB cranksets, opt for a DUB-specific press-fit unit sized to your shell (this model targets 86–86.5mm shells with 41mm ID). Consider durability vs. weight: sealed steel bearings offer lower cost and dependable service life compared with ceramic alternatives. Also factor in installation — press-fit BBs need correct tooling and shell preparation, so budget for a professional press or a shop install if you lack the tools.
