Wheels Manufacturing Derailleur Hanger 108

Derailleur hangers are frame-specific, not universal. You must match the hanger to your specific bike frame's make, model, and year. We recommend using the Wheels Manufacturing hanger finder tool or comparing your current hanger visually to the images provided to ensure an exact match.
