Product Details

Overview & Technology

Wheels Manufacturing BB-BSA30 converts a threaded British (BSA) frame shell into a robust home for 30mm spindle cranksets designed for BB30 Wide/BB30a/386EVO standards. Built around Enduro ACB bearings and precision-machined cups, this unit is engineered for riders who want the stiffness and durability of a 30mm spindle with the reliability and serviceability of a threaded bottom bracket. The cups are CNC-machined from high-strength aluminum and finished in a hard black anodize for corrosion resistance and long service life. Bearings are Enduro ACB sealed units—specifically selected for angular-contact load handling, minimal drag, and confidence under sustained power, making the BB-BSA30 suitable for spirited road riding, gravel assaults, and mixed-surface training.

Key Features & Construction

Precision cups and premium bearings: The BB-BSA30 uses threaded BSA cups that accept Enduro ACB bearings sized for a 30mm crank spindle. CNC-machined aluminum construction keeps weight low while providing a stiff interface between frame and crank for efficient power transfer. Real-world benefits include reduced bearing play under load, improved pedaling efficiency, and easier service compared with press-fit conversions. The sealed Enduro bearings shed grime and keep rotating smooth mile after mile; the anodized cups resist corrosion in wet conditions.

Fit, Compatibility & Installation

This unit is designed for frames with a BSA (British) threaded shell and shell widths of 68mm or 73mm. It accepts cranks with a 30mm spindle diameter specifically from BB30 Wide, BB30a, 386EVO and compatible systems (for example Rotor 3D+ and SRAM BB30 Wide). Important: it will not work with standard BB30 cranksets that require a different bearing interface—confirm your crank uses BB30 Wide/386EVO-style interface and has a spindle length of at least 104mm. Installation requires a 16-notch MegaEvo-compatible tool such as an FSA MegaEvo wrench or the Park Tool BBT-29. Use standard threadlocker/anti-seize practices where recommended, torque to manufacturer specs, and check bearing preload if applicable during assembly.

Who This Bottom Bracket Is For

The BB-BSA30 is aimed at riders who have a BSA-threaded frame but want to run 30mm spindle cranks that use the BB30 Wide/386EVO interface. It’s ideal for road riders and mixed-surface cyclists who prioritize a stiff crank-to-frame connection and long-lasting sealed bearings without the fuss of press-fit systems. If you have a standard BB30 crankset, or a press-fit frame, this is not the right part. Choose the BB-BSA30 when your crankset lists compatibility with BB30 Wide/BB30a/386EVO and you want the added serviceability of a threaded bottom bracket solution.

Frequently Asked Questions

Will this work with standard BB30 cranksets?

No. The BB-BSA30 is specifically for BB30 Wide / BB30a / 386EVO style cranks with a 30mm spindle. Standard BB30 interfaces differ in bearing seat dimensions and will not fit this cup/bearing assembly.

What tools do I need to install the BB-BSA30?

You need a 16-notch MegaEvo-compatible bottom bracket tool such as the FSA MegaEvo wrench or Park Tool BBT-29. Use the correct torque settings and threadlocker or anti-seize as recommended by your frame/crank manufacturers.

What bearings are used and how serviceable are they?

This model ships with Enduro ACB sealed bearings, engineered for angular contact loads and durable sealing. Bearings are replaceable when worn—cups accept standard-size Enduro ACB replacements for straightforward maintenance.

Will this fit my frame?

It fits frames with a British/BSA threaded bottom bracket shell and shell widths of 68mm or 73mm. Verify your frame uses BSA threads; if you have a press-fit shell or a different threading standard, this unit will not fit.

Do I need a minimum spindle length for my crank?

Yes—your crank’s spindle should be at least 104mm long to ensure proper chainline and bearing coverage when used with this bracket. Check the crank manufacturer’s documentation if unsure.

Is the BB-BSA30 suitable for wet or muddy conditions?

Yes—the anodized cups and sealed Enduro bearings offer good protection against moisture and grime. However, regular inspection and servicing will prolong bearing life in harsh, wet environments.

Buying Guide

When choosing a bottom bracket adapter like the BB-BSA30, match three things: your frame shell type (BSA threaded 68/73mm), your crank spindle diameter (30mm) and the crank interface standard (BB30 Wide / 386EVO). Prioritize sealed bearings from reputable makers—Enduro ACB bearings offer good durability and serviceability for road and mixed-surface use. Also consider serviceability and tools: threaded solutions like this one are often easier to maintain than press-fit systems. Make sure you have the correct 16-notch MegaEvo-compatible tool for installation, and plan to inspect seals and bearings periodically, especially after wet rides.
