Well I have to say that I haven't put that much research into this. I have just saved an old Gitane from a certain death and I am now curios which model it could be. The frame is from 531 tubing (well at least the main triangle). Equipped with huret dérailleur and shifters (10 speed btw), weinmann 605 brakes and sugino crank. I would guess that it might be a "tour de france" model but I am somewhat confused by the campy drop-outs. It also has 3ttt stem and handlebar. Anyone got an idea which model it could be?
