Product Details

Overview & Technology

SRAM DUB BB30 Road Wide 68mm (Model ID: BB-DUB-BB30-A1, MPN: 00.6418.017.003) is a press-fit bottom bracket engineered for road frames with a BB30 shell and 68mm shell width. It uses SRAM's DUB interface to accept 28.99mm spindled cranks and installs into a 42mm cup diameter shell opening. The assembly is finished in durable black and ships compact (4.4" x 3.25" x 2.25") at about 0.1 lb. Technology highlights include the DUB interface that standardizes spindle diameter across SRAM's road crank lineup and sealed steel bearings tuned for long life and reliable performance. The result is a low-maintenance, high-stiffness interface that reduces lateral play and improves power transfer on road rides and group efforts.

Key Features & Benefits

Precision-fit cups and sealed steel bearings provide reliable support for 28.99mm DUB spindles. The 42mm cup diameter and press-fit BB30 design keep the assembly compact while protecting bearings from contamination and road grit. Steel bearings strike a balance between cost, durability, and predictable wear characteristics in typical road conditions. Real-world benefits: quieter pedaling with reduced creaks, improved pedaling stiffness for sprinting and climbing, and simplified parts commonality if you run SRAM DUB cranks. The Road Wide 68mm variant matches BB30 shells with wider tolerance or frames built to the 68mm road spec.

Fit, Compatibility & Installation

This bottom bracket is made specifically for frames with a BB30 shell and a 68mm shell width. It accepts cranks with a 28.99mm DUB spindle — primarily SRAM DUB road cranksets. The cups are sized for a 42mm press diameter; verify your frame's bore and prep the shell per SRAM's press-fit guidance before installation. Installation notes: press-fit BBs require a bearing press tool, correct alignment, and a torque-controlled press to avoid frame damage. Frames with out-of-spec BB30 bores or heavy corrosion may need reaming or professional attention. For durable service life, use the recommended grease on cups and follow SRAM's service intervals.

Who This Is For

This DUB BB30 Road Wide 68mm unit is aimed at road cyclists running SRAM DUB cranks on BB30 frames who want a straightforward, OEM-compatible bottom bracket solution. It's ideal for riders who prioritize a stiff drivetrain and low-maintenance sealed bearings for everyday training, club rides, and race-day efforts. If you ride on variable roads and want predictable bearing life without exotic ceramic upgrades, the sealed steel bearing construction delivers dependable performance at a competitive price point.

Frequently Asked Questions

Will this bottom bracket fit my frame?

This unit fits frames with a BB30 shell and a 68mm shell width with a 42mm cup bore. Confirm your frame's BB standard and bore diameter before purchasing; frames with out-of-spec or damaged bores may require reaming or professional installation.

Is it compatible with non-SRAM cranks?

It's designed for 28.99mm DUB spindles, which are standard on SRAM DUB cranks. Some third-party cranks with the same spindle diameter may fit, but compatibility isn't guaranteed—always check spindle diameter and interface spec.

What maintenance does the sealed steel bearing require?

Sealed bearings are largely maintenance-free but benefit from periodic inspection. Keep the area clean, check for play or roughness every few thousand kilometers, and replace bearings if you detect noise or increased friction.

Do I need special tools to install it?

Yes—press-fit bottom brackets should be installed with a proper bearing press tool and alignment guides to avoid damaging the frame or bearings. If you're unsure, have a professional mechanic press the cups in.

Can this BB help eliminate creaks in my setup?

It can—many creaks from the bottom bracket area stem from worn bearings, loose cups, or mismatched interfaces. A properly installed DUB BB30 with sealed bearings often reduces or eliminates those noises, provided the frame's shell is square and within tolerance.

Are the bearings replaceable?

Yes, the pressed-in bearing cartridges can be removed and replaced when worn. Replacement intervals depend on riding conditions, but inspecting bearings annually is a good practice.

Buying Guide

When selecting a road press-fit bottom bracket, match the BB standard (BB30), shell width (68mm), and cup bore diameter (42mm) to your frame. Confirm the crank spindle diameter—this SRAM DUB BB30 accepts 28.99mm DUB spindles and is the correct choice if you run SRAM DUB road cranks. Consider bearing material and serviceability: sealed steel bearings offer dependable life and easier replacement at a lower cost than ceramic options. Finally, plan for proper installation—press-fit units need a bearing press and correct shell preparation to avoid creaks and ensure long service life.
