One of the premier bikes of Schwinn but not what I would call a lightweight racer. Still if you have a liking for those early Schwinn bikes these are very interesting. I had one or two of these in my past but they are long gone. You can read the specs on Bob Hufford's site at the link below. BTW, they did use a Titan stem as perviously mentioned by another listmember.
