I'm currently building up an '88 Schwinn Premis road bike as a SS. I already have two fixed-gear bikes and I didn't think I really needed another one. Besides, I had a set of 28h tubular wheels with old Campy Record hubs I was trying find a home for. I ordered a Shimano 18t freewheel for it at the LBS.

The bike is not finished yet but it feels incredibly light (compared to my other bikes, anyway) so I'm going to try 52 x 18 grearing.

I don't shift gears very much anyway, prefering to put it in a gear I like and just leave it at that.
