The answer I gave below should have said 1982-1983 and not mid 70s. Sorry about any confusion I may have caused. If you'd like to see the whole spec sheet write me off link. Around mid 70's the Champion was all Campy and the Team Pro was all French with Columbus Tubes. This includes Simplex deraillures This according to Motobecane Adds in Bicycling Magazine.
