Wheels Manufacturing makes derailleur hangers that mean business—built tough with precise machining for flawless shifting every ride. You’ll feel the difference in every gear change, all without sacrificing fit or function.

Our parts deliver trail-proven durability and high-quality materials at everyday value—that’s where passion meets practicality.

Since 1988, Wheels Manufacturing has grown from a small machine shop in Boulder, Colorado into one of the world’s largest suppliers of bicycle derailleur hangers, specialty tools, repair parts and components. Based nowadays in Louisville, Colorado, they still mill most products in the U.S.A., using their own machinists and engineers to keep quality tight. All of their parts are made to exact tolerances with the highest quality materials.

That long history matters when you're fixing or upgrading your bike today. You get parts crafted with real experience, designed to work with hundreds of bike frames, and built tough enough to take knocks without sending shocks through your frame. That means reliable performance, shifting you can trust, from entry rides to mid-tier adventures.
