My apologies, I'm a newbie here and figuring out posting has been interesting. I'm also trying to avoid zombie threads, the last post was less than a year ago so I hope I'm good. Question is for Chas, somebody I followed for years over on GitaneUSA and know well of his expertise. Chas, how are you fixing the start of Gitane's foil era at 1968? I know that there are grey areas, like when older stock was updated with newer decals but I'm trying to date a European-market Gitane Champion du Monde that has "100" designation (pre-1968) as well as some foil era decals.. The frame appears to be pre-bike-boom, Nervex Pro lugs; Campy dropouts, finished seat stay caps (pre-Carre-style ); 3 tubes/fork 531, and no chrome socks. It may have been a curated specimen that got later decals but I've seen other Gitanes with early features that also have some combo of the foil decal set. As I'm an archaeologist assigning dates becomes a terrible, sometimes unachievable, obsession. Anyway, can you give me some insight? I live in Marin and would happily show you the frame sometime. Best., Mark...I'll post pic...but the forum is telling me this message is over 70,000 characters, like I said, posting here as been interesting.
