Welcome to the Forum, I'm a Supersport and Varsity/Continental fan myself.

Looking forward to pictures as your project comes along. The Schwinns with the taller frames catch my eye, give me enough top tube length to work with when riding at a sporting intensity.

I was finally able to raise my Supersport's tire pressure a good bit (safely to 80psi with 1-1/8" tires) by laying a thicker rim tape in, though it was a real challenge to get the wide Velox tape in place going "wall to wall" across the undulating inner rim surface. I'll have to keep an eye on the tape's placement over time, too bad that this particular model of Weinmann rim seems just small enough (in diameter) to allow a tire's bead to lift in places. I even contemplated a layer of hard epoxy glue to take up slack in the tire's bead, perhaps painted on along the lower ledge of the inside corners. Not such an easy fix, as various brands of tires all seemed to be limited to reliable pressures no higher than 70-75psi!

I was looking for a blue one for a few years, but was quite happy to find this one a few years back, now modified for a sporting 6-speed freewheel, still using an Allvit derailer and steel cranks and kickstand for "sleeper" value on a bike that I ride hard these days. I've tried to get this photo to fit a normal computer screen, hope it worked.
