For more than 30 years, White Industries has refined its components through real-world riding and continuous innovation. Today, the M30 reflects that same commitment to precision, reliability, and long-lasting performance.

A30 Adventure Cranks
The White Industries A30 Crankset is a lightweight, precision-machined crank designed for select gravel, all-road, and custom adventure bikes. We machine, finish, and assemble every crank in our Petaluma, California facility. As a result, the A30 delivers exceptional stiffness, lasting durability, and premium American craftsmanship.

The A30 is part of our 30mm spindle crank family, which also includes the M30, R30, and G30. For more than 30 years, White Industries has refined its components through real-world riding and continuous innovation. Today, the A30 reflects that same commitment to precision, reliability, and long-lasting performance.

The A30 combines our R30 road crank arms with our M30 mountain spindle. This unique configuration delivers a mountain bike chainline with a narrower Q factor than a traditional mountain crank. Therefore, the A30 is designed specifically for gravel and adventure frames with 73mm bottom bracket shells that require additional spindle length without the wider stance of the M30 crank.

Although the A30 won’t fit most bikes, it solves a very specific challenge for custom frame builders and riders. If your frame requires a longer spindle while maintaining a narrower crank profile, the A30 provides the ideal solution.

Choose from two crank arm colors, six extractor cap colors, three 1x chainline options, an optional 2x chainring configuration, and five crank arm lengths. As a result, it’s easy to build a crankset that fits your unique frame and riding style. Whether you’re building a custom gravel bike or an adventure bike with non-standard geometry, the A30 delivers premium Made in the USA performance built to last.

Made here in our shop, the Square Taper Road Crank draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.

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.

External T47 Bottom Bracket

Product Details

White Industries external T47 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. “T47” is a bottom bracket standard that White Industries helped develop in 2016 and allows for a greater weld area for bigger frame tubes as well as room inside the shell for internally routed cables and wires.

The “T” stands for “threaded” and the “47” is the nominal 47mm outside thread diameter of the cup. T47 bottom bracket cups are not compatible with the much smaller (and more common) threaded BSA BB shells. The “external” designation on this bottom bracket refers to the fact that the bearings sit “outboard” of 68mm and 73mm wide bottom bracket shells, as opposed to our “internal” T47 bottom brackets where the bearings sit “inboard” of 86mm and 92mm wide bottom bracket shells. If you have an 86mm or 92mm wide T47 bottom bracket shell on your frame, you will need one of our “internal” T47 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.
