Wheels Manufacturing Dropout-555 Derailleur Hanger

Derailleur hangers are frame-specific, meaning they must match the exact mounting pattern of your bike's dropout. This model is specifically designed for Aventon frames, but we strongly recommend comparing your current hanger against the product photos or checking your bike manufacturer's compatibility list before purchasing.

The hanger is designed to be the 'weak link' in your drivetrain. By using CNC-machined aluminum, it is engineered to bend or break during an impact, effectively absorbing the force that would otherwise damage your frame's more expensive dropouts.

Yes, this part includes the necessary mounting hardware to attach it to your frame. You will simply need your own hex keys to remove the old hanger and secure the new one.

While it is sometimes possible to straighten a hanger, the metal is often weakened and fatigued during the bending process. Replacing it with a new, CNC-machined unit like this one is the only way to guarantee factory-level shifting accuracy and prevent future mechanical issues.

No specific maintenance is required, but it is good practice to check that the mounting bolts are tight during your regular tune-ups. If you notice your shifting becoming inconsistent or ghost-shifting occurs, inspect the hanger for any visible bends or misalignment.
