Compatibility Assistance

Send photos of the original hanger and confirm your frame model/year and catalogue number before selecting P-141A or P-141B. The supplier's repeated C1355146 reference and missing variant-to-model map need checking.

For help, send BicyclePartsZA your exact Bianchi model, model year and frame type, plus clear photos of your existing hanger from both sides and the frame dropout.
