My dad has an old Raleigh Grand Prix he bought in the late 60's or early 70's. He road it to work at the time, but it has since been stored in a garage and not seen any use in almost 20 years. I'm going to clean it up and use it for sunday cruising/art. Anyone have any tips, suggestions, or knowledge of this model? I've torn down and fixed up some old ten speeds before, but nothing near this quality.
