Wheels Manufacturing Derailleur Hanger 477

Derailleur hangers are frame-specific, meaning they must match your bike's exact make, model, and year. We recommend using the Wheels Manufacturing hanger identification guide or comparing your current hanger visually against the product photos to ensure the bolt pattern and shape match perfectly.

The hanger is engineered to be the weakest link in your drivetrain. By bending or breaking during an impact, it absorbs the force of a crash that would otherwise damage your frame's dropout, which is often a much more expensive or impossible repair.

While some hangers can be temporarily straightened with a dedicated alignment tool, the metal often weakens and fatigues during the process. Replacing the hanger is the only way to guarantee the precise alignment required for smooth, reliable shifting.

Installation typically requires only basic hand tools, such as a set of hex keys, to remove the mounting bolts. However, once installed, you should always check your derailleur alignment and limit screw adjustments to ensure your gears shift correctly.

Absolutely. A bent hanger is a common trail-side failure that can immediately end your ride. Keeping a spare on hand ensures you can perform a quick swap and get back on the bike without waiting for shipping.
