I've noticed where the SS/FG rage has driven the price of old road bikes way up. IF you can find a $20 conversion bike, it'll be a heavy old Schwinn. Used to be able to pick them up for $5-$10 at yard sales. I have a couple Schwinn tanks in my garage right now, not to mention a vintage Trek that would make a good fixie. Hmm, I might be sitting on a gold mine! Keep it up, folks!
