Those are some amazing Schwinns you have, very nicely presented. The Superior in particular looks very tasty, those just don't get enough bandwidth IMHO. Until I became active here, I had never even heard of them, I haunted the local Schwinn shop, Escambia Schwinn Cyclery, for several years in the early 70s, and none were on the racks there that I can recall. Now I see them here occasionally and they seem to be first rate bikes. If you would, please post some pics as you restore/clean up the Superior, and when it is completed.
