Single and Double Freewheels

In 2002, Doug White set out to build better Single and Double bicycle freewheels. The goal wasn’t to reinvent the category — it was to improve it. Stronger. More precise. Built to last. More than two decades later, White Industries freewheels remain the benchmark for riders who demand durability, reliability, and precision machining.

Every White Industries single speed freewheel is designed and manufactured with long-term performance in mind. Each unit is precision-machined from high-quality materials and carefully assembled to ensure smooth operation and dependable engagement. The result is a freewheel that feels solid, spins smoothly, and performs consistently ride after ride.

Unlike many disposable alternatives on the market, White Industries freewheels are fully rebuildable. Internal components can be serviced and replaced, extending the life of the product and reducing unnecessary waste. This serviceable design has made them a favorite among riders who appreciate components built for longevity rather than short-term replacement.

Durability is at the core of every design decision. From the robust body construction to the precise pawl engagement, these freewheels are engineered to handle the demands of single speed mountain biking, commuting, touring, and everyday riding. Whether you’re grinding up climbs or spinning through city streets, they’re built to perform reliably under real-world conditions.

For riders who value quality machining, dependable performance, and serviceable bike components, White Industries freewheels deliver exactly what matters most.

Simple. Durable. Dependable.

Designed and made in California, these freewheels carry forward the same philosophy that has defined White Industries products for decades: build it right the first time, and build it to last.

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.

ENO Flip Flop Hub

Product Details

The ENO singlespeed hub has long been synonymous with the White Industries brand and remains a sought after item. 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”, we say, “ENO”, like Brian Eno. The ENO Flip Flop hub takes a standard threaded freewheel on one side and our proprietary splined fixed gear cogs on the other. The ENO hub comes in five axle variations, each using the same hub shell: two with eccentric axles, and three with straight axles.

The eccentric axle ENO hubs are called “ENO ECC” hubs, and allow you to convert your vertical dropout frame to singlespeed or fixed gear, offering 20mm of total fore-aft adjustment. They comes in 130mm and 135mm axle widths and use bolts with stepped washers to hold the hub in the frame. A 12mm x 142mm Thru axle option is not available in the eccentric version.

The straight axle ENO hubs are simply called “ENO” hubs. These are designed to be used with frames that have either slotted horizontal dropouts, adjustable dropouts, or an eccentric bottom bracket. They come in 130mm, 135mm, and 12mm x 142mm Thru. The 130mm and 135mm axle widths uses bolts with stepped washers to hold the hub in the frame, while the 12mm x 142mm Thru axle version uses a 12mm Thru axle (supplied by you, to fit your frame) to hold the hub in the frame.
