I've looked around but can't seem to find the info needed. Can anyone give me more info on this bike like the model year? It has Ventoux and Vitesses 12spd on the top tube and Reynolds 501 on the frame. It has Sachs Huret front and rear derailleurs, Stronglight cranks and Weinmann brakes. I'm thinking about purchasing it from a friend but don't I want to run into trouble with any threading issues. Thanks for the help.
