I had one of these in PR, bought it new in '87. It was stolen 2 years later. It rode very well in rough pavement.
It was this exact color. Close to Celeste, but I think Schwinn called it "mint green"
I had ditched the pie-pan, put 700c wolbers with avocet k20 23mm kevlar-belted slicks on it, and pedals with clips and straps. It actually was a nice little rocket. I still miss it. One day I'll get one off CL or something. It'd have to be this color, and original. And of course, I also plan to get her more upscale sisters, a circuit, a paramount.. one day. I loved the old Schwinns, even the ones I couldn't get.
Yours is beautiful. Thanks for posting the pix, it brought back fond memories of 30 mph downhill runs on the way back home at 3 am after a night of being up to no good
