I could want to buy it if you have an older ten speed (very popular in the 70s and 80s) just sitting in your garage!
Common brand names are Schwinn, Raleigh, Trek, Nishiki, Miyata, Shogun, Puegeot, Sekai, Lotus, Centurion, Motobecane ... But there are others too!
I understand that these bikes are dirty and most likely have flat, dry rotted tires ... That's to be expected. I've gotten into the pastime of fixing these old bikes up. If they have actually been long term saved outdoors (heavy rust), not interested. If you have one, text or e-mail me a couple photos and I could jut come get it!
Thanks. Some example images to jog the memory of what a ten-speed appearances like ...
