The mid 70's Gitane Tour de France came with all sorts of different parts. The usual was the "standard" French Simplex Criterium/ Mafac Comp/ Stronglight93/Normandy Luxe Comp setup, but I remember seeing many with Sugino Mighty Comp cranks, Weinmann centerpulls, Nuovo Tipo hubs, and even Campy Gran Sport( NOT Nuovo Gran Sport) derailers. 700c clinchers on Weinmann rims were also common. I'm speaking of new, unmodified, out of the box bikes.
