Product Details

Overview & Technology

SRAM DUB PF92 SuperBoost+ (Model ID: BB-DUB-PF-A1, MPN 00.6418.020.000) is a purpose-built press-fit bottom bracket for BB92 shell MTB frames using SRAM's DUB system. The unit combines a 28.99mm DUB spindle interface with sealed steel bearings housed in 41mm outer-diameter cups to deliver durability and predictable fitment for modern SuperBoost+ bikes. The DUB platform was designed to standardize spindle diameter and bearing life across SRAM crank families so you get improved bearing life, better stiffness-to-weight and simplified serviceability. The PF92 cups are optimized for 92mm shell widths and use tight tolerances to minimize play and creaking when installed correctly.

Key Features & Benefits

Durable sealed steel bearings: Steel bearings balance longevity and cost-effectiveness for aggressive trail use where mud and grit are common. Sealing reduces contamination and keeps rotation smooth under load. DUB 28.99mm spindle interface: Matches SRAM DUB cranks to preserve stiffness and chainline while keeping compatibility across multiple crank models. The 41mm cup diameter ensures a stable press-fit and even load distribution in BB92 shells.

Fit, Compatibility & Installation

This bottom bracket fits frames with a BB92 press-fit shell and 92mm shell width — commonly found on many modern mountain and SuperBoost+ frames. It requires cranks built to the DUB standard (28.99mm spindle). It will not accept 24mm (Shimano) or 30mm spindle cranks. Installation is a press-fit operation: cups are pressed into the frame to the specified depth. Use a dedicated press-fit tool and alignment driver to avoid shell damage. Proper installation technique and the right retaining compound or grease greatly reduce the risk of noise and movement over time.

Who This Is For

Riders running SRAM DUB cranks on modern MTB frames with BB92 shells — especially SuperBoost+ frames — will benefit most from this bottom bracket. It’s tuned for trail and all-mountain use where durability and reliable power transfer under variable conditions matter. Mechanics and home wrenchers looking for a simple, OEM-matched replacement for DUB-equipped bikes will appreciate the exact fit, sealed bearings and proven SRAM engineering behind this PF92 unit.

Frequently Asked Questions

Will this fit my frame?

This bottom bracket fits frames with a BB92 press-fit shell and a 92mm shell width. Confirm your frame uses the PF92 standard (often labeled BB92) before ordering — it won't fit threaded shells or other press-fit widths.

Which cranks are compatible with the DUB PF92 SuperBoost+?

Compatible cranks are those using SRAM's DUB spindle (28.99mm). It is not compatible with 24mm Shimano-style or 30mm axle cranks. Always check your crank spec or consult SRAM documentation if unsure.

Do I need special tools to install it?

Yes. A proper press-fit bearing press and BB92-specific drivers/aligners are recommended to press cups squarely into the frame. Using the wrong tools can damage the frame or cups and lead to noise and premature wear.

Should I use grease or retaining compound during installation?

Many mechanics use a thin layer of waterproof grease on the cups and a light retaining compound (Loctite/tribologically compatible product) depending on frame tolerances. Follow SRAM installation guidelines and your frame manufacturer's recommendations to minimize creaks.

How do steel bearings compare to ceramic options?

Steel bearings offer robust durability and better impact resistance at a lower cost; they're well suited to muddy trail and enduro use. Ceramic bearings are lower friction but more expensive and may be less forgiving in contaminated environments.

What maintenance does this bottom bracket need?

Sealed bearings are low-maintenance but benefit from periodic inspection for play and roughness. If bearings show wear or contamination, replace the unit. Proper installation and sealing are the most important factors to extend service life.

Buying Guide

When choosing a press-fit bottom bracket, prioritize compatibility (shell standard and crank spindle diameter), bearing type, and ease of installation. For SRAM DUB users on BB92 shells, the DUB PF92 SuperBoost+ is a direct, OEM-matched solution that balances durability and performance. Consider your riding conditions: sealed steel bearings are a practical choice for trail and enduro riders who need resilience to mud and impacts. Factor in installation tools or local shop service costs when budgeting for a press-fit replacement.
