Wheels Manufacturing Derailleur Hanger 153

Derailleur hangers are frame-specific, not universal. You must match the hanger's shape and mounting holes to your specific bike frame; the best way to do this is to compare your current hanger against the visual reference on our site or check your bike manufacturer's compatibility list.

Yes, this hanger is CNC machined from 6061 aluminum, which typically offers higher precision and better structural integrity than many factory-cast originals. While it is built to be durable, it is still designed to act as a sacrificial part that bends or breaks to protect your frame's derailleur mount during an impact.

Yes, it includes the necessary M8 chainring bolt required for installation. You will only need basic tools, such as a hex key, to secure it to your rear dropout.

The black anodized finish is more than just aesthetic; it provides a hardened, corrosion-resistant layer that protects the aluminum from the elements. This helps ensure the hanger maintains its structural integrity and doesn't seize to your frame over time.

While you can sometimes temporarily straighten a derailleur hanger using a dedicated alignment tool, it is generally recommended to replace it once it has been bent. Repeated bending weakens the aluminum, which can lead to unpredictable shifting or sudden failure.
