I finally have a coppertone Schwinn, and it's an early 10 speed. Schwinnmesa found it at a dump and sold it to me. If it had the original rims, I would restore it to it's original glory, but I just have the frame, so it will be custom. I have a Sachs 3 speed w coaster brake with 26" rims along with a pair of Kenda flame 2.125 tires. If they are too wide, I'll go with 1.95 or 1.75. Cranks and sprocket are from a 64 Starlet. Handlebars might be from a 3 speed Raleigh. I've got a few choices for a seat, mainly Brooks mattress saddles. I wish I had another leather Brooks.
