yeah that looks special for sure, but I can't ID this one. Check out the seat post size, the specs for '85 models show a Columbus Aelle model used a 26.2 post and the Team Pro used a 26.4 (tho it's 531 for '85) so it seems that Gitane was still building with Metric sized tubesets back then. If it's a 27.2 then I'm going back to my guess that's it's a top USA builder...as yet unknown to me.
