I'm trying to find a vintage bike for a city commuter while I restore my Moto and build up my Bianchi frameset. I'm looking at several, including some Gitanes. I'm sort of familiar with Gitanes because my parents and sister all got Gitanes during the 70s bike boom. But I can't find any information about frames and models.

The vintage Gitanes I've seen are Tour de Mondes. I'm asssuming this is a plain (heavy) steel frame. Is that right?

What models of Gitane are the ones to look for? I'm not looking for a racing bike, just a good quality frame that I can use as a city bike.
