Compatibility note: Compatibility information is provided as a guide and may not include every compatible bicycle. Derailleur hanger fit can vary by model year, frame version and production revision, so a listed bicycle may use a different hanger.

Before ordering, check the bicycle brand, exact model, model year or frame generation, the shape of the original derailleur hanger, and any OEM or part numbers where available.

If several visually similar derailleur hangers are available for your bicycle, compare the product photos and compatibility information carefully.
