Bottom Bracket Shell Type: BSA Threaded

Bearing Press
nstalling bearings requires precision—not guesswork.

The White Industries Bearing Press help you install bearings straight and evenly every time. They reduce the risk of damaging new bearings during installation while ensuring consistent, accurate results.

When paired together, the bearing guides and our precision bearing press apply smooth, controlled pressure throughout the installation process. As a result, bearings seat correctly without unnecessary stress on the bearing or component.

The system is easy to use. All you need are two 13mm combination wrenches to complete the installation.

Choose the configuration that best fits your needs:
- Complete front and rear hub bearing press
- Complete bottom bracket bearing press kit (includes three sizes)
- Individual bottom bracket bearing presses for specific bearing sizes
Whether you’re a professional mechanic or a home mechanic servicing your own bike, this tool system makes bearing installation simple, repeatable, and reliable.

Proper tools help protect your components, extend bearing life, and ensure every installation is done right the first time.

Built to support serviceability. Built to last.

Bottom Bracket Bearing Removal Tool

Product Details

This two-piece tool was designed as a more affordable way to remove 29mm and 30mm bottom bracket bearings from BSA, T47, and PF30 bottom bracket cups. Currently your options are either invest in an elaborate bearing puller and all the appropriate little pieces to fit each specific bearing, or use a screwdriver to knock your bearings out and probably gouge the inside of your cups.

This tool does not require any other removal tools beyond either a rubber mallet, a bench vice, or an arbor type press. BSA cups with 29mm or 30mm bearings are notoriously hard to disassemble because there is almost zero clearance between the I.D. of the cup and I.D. of the bearing. But you already knew that, which is why you’re reading this. So invest in the correct tool for the job!

Square Taper ENO Cranks

Product Details

This is our “Old School” mountain and single speed crank designed for J.I.S. square taper bottom brackets. What does “ENO” stand for? It’s “ONE” backwards and mirrored, a CNC programming error made years ago that we decided was kind of cool. So instead of “ONE” (a nod to the fact that single speeders loved this crank), we say, “ENO”, like Brian Eno.

Made here in our shop, the ENO Square Taper Crank draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design. This has been and continues to be the go-to crank for thousands of mountain and singlespeed builds where riders are looking for a simple, proven system that performs year in and year out.

External BSA Bottom Brackets

White Industries external BSA style bottom brackets are made here in our shop and feature Enduro stainless steel angular contact bearings or optional Enduro XD-15 ceramic-hybrid radial bearings. We offer them with three different bearing sizes to help you fit your favorite crank to your favorite bike.

“BSA” bottom bracket shells and cups are named after the Birmingham Small Arms Company which created the thread standard used in this system. It’s also referred to as “British” or “English” style and is the most common type of system found on modern bicycles. The “external” designation refers to the fact that the bearings will sit outboard of your frame’s bottom bracket shell as opposed to being tucked inside the shell as you would find on some styles of BSA bottom brackets.

Square Taper Bottom Bracket

Product Details

This is one of the first products White Industries ever produced way back in 1988. We’ve updated the design along the way and it remains a popular item all these years later despite the introduction of more “modern” crank and bottom bracket designs. This is a BSA “square taper” style bottom bracket which uses BSA threads and a spindle that uses a square/tapered crank arm interface. It is compatible with White Industries ENO square taper and Road Square Taper cranks as well as other brands that use a J.I.S. (Japanese Industrial Standard) taper such as Shimano, Sugino, and others. These bottom brackets are not compatible with Campy cranks which use an ISO or “Campy” style taper.
