I understand, I want to experience for myself the difference between a classic steel frame and an aluminum or a modern steel or titanium. Wide comfy tires vs. narrow fast. Every bike seems better than the last, then ride an old favorite and appreciate it all over again. My favorite is still the old Super Sport (you can abbreviate it as 5S for Schwinn Super Sport Single Speed).

Also I saw a great solution for the 21.1mm stem, they took a threaded to threadless stem adaptor and turned it on a lathe down to 21.1mm. I really changed the look and opened all kinds of options for bars.

I also have a basement full of interesting bikes that I do not have time to appreciate. Now if I could just bring myself to part with them. The Super Sport could do it if I can do my part.
