I'm wondering that. I need to take a closer look at it. It looks like a late 70's early 80's model because the paint job and logo seem more modern than the type font on it's earlier bikes. It is made in France though (not tiawan). Did motobecane convert over to the english/ISO threading around then? If it's english thread I don't think it'll be too hard to convert this. I was assuming it was french/swiss threaded.
