It is older than '82 for sure. My brother has a Gitane purchased in Paris by my uncle in '78 or '79 that had the full 600EX group except for the hubs. My uncle had the shop swap out the tubulars for clinchers and the bike came with Maillard low flange hubs. I suspect the original wheels had 600EX hubs (which I think used a 6 speed cassette in back).
