Hub Sturmey Archer

Sturmey Archer Flip Flop Hub – versatility and reliability for fixed gear and single speed wheels

The Sturmey Archer flip flop hub is a must-have component for building a rear bicycle wheel designed for fixed gear, single speed, or urban riding. Known for the durability of its parts and the precision of its bearings, Sturmey Archer delivers a hub that combines simplicity, strength, and adaptability.

Thanks to its double-threaded design, this flip flop hub allows you to switch easily between a fixed cog and a freewheel, offering two drivetrain setups on a single rear wheel.

A flip flop hub designed for versatility

The flip flop hub concept is based on a reversible axle system:

• one side is threaded for a fixed gear sprocket with lockring,

• the opposite side accepts a freewheel, ideal for relaxed or city riding.

This configuration is especially popular on frames with horizontal dropouts, making chain tension adjustments quick and easy when flipping the rear wheel.

Sturmey Archer quality: smooth rolling and long-lasting performance

Built with a precision-machined hub shell, the Sturmey Archer flip flop hub provides excellent wheel stiffness, even under heavy pedaling loads. Depending on the version, sealed or loose ball bearings ensure smooth rotation, effective sealing, and long service life—perfect for daily commuting.

The wide flanges improve spoke bracing angles, resulting in stronger wheel builds, better spoke tension, and increased rear wheel stability on both track and urban setups.
