Wheels Manufacturing Derailleur Hanger 88

Derailleur hangers are frame-specific, not universal. You must match the hanger shape and mounting pattern to your specific bike frame, as even slight variations in geometry will prevent proper shifting. We recommend checking your bike manufacturer's website or comparing your current hanger visually against the hanger 88 model before purchasing.

Yes, this kit includes two M4x10 flat head screws, so you have everything you need to mount it directly to your rear dropout.

The hanger is designed to be a sacrificial part. Using 6061 aluminum allows it to bend or break during an impact, which absorbs the energy and protects your frame's more expensive rear dropout from permanent damage.

The anodized finish is highly durable and resistant to corrosion, meaning it will maintain its appearance and structural integrity much longer than raw or painted aluminum. While it may show minor surface scratches from normal use, it will not rust or degrade in harsh riding conditions.

No specific maintenance is needed, but you should periodically check that the mounting screws are tight. If you experience poor shifting performance or notice the hanger has been bent after a crash, it should be replaced immediately to ensure drivetrain accuracy.
