I was given this old Puch, the decals are gone, it looks like it was repainted but not sure, it has some surface rust. Suntour components, cottered crank. I am not really into vintage bikes but I will have a full campy group coming off one of my other rides - will have to stretch the chain stays out to make a 9 speed casset fit though as this is a 5 s[eed casset. It will need repainting as well. Is this worth it or is it best left to the crusher? Thie bike does seem to fit OK - maybe a tad small for me.
