I have an old, orange Vintage Peugeot that I'm not sure about the age or model of. It has Simplex derailleurs, shifters on the downtube, and Mafac breaks, and it did have leather saddle with an illegible brand name. I took it to a local bike shop and the guy said it was worthless and that everything needed to be replaced. He seemed to think that all French bikes are worthless. I like it however, and the frame is pretty decent, so I'd like to work on it. Any suggestions on components that are compatible? I'm thinking of changing it to a single speed for now. Also, anyone know what model it might be?
