My heaviest bike is not vintage, but my ready to tour Surly LHT with Surly racks f/r and fenders=35lbs (62cm frame). Adding panniers and stuff in them it ads up quickly. I don't feel the weight on the road really only when I have to carry it down/up stairs or something like that. My lightest bike is one of my track bikes at 18-19 lbs depending on what parts are on it at the time.
