Hi. I am new to the forum. Been riding a "10 speed" since my Schwinn Varsity back in the late 60's. My interest in bike styles/construction is frozen somewhere in the 80's or so. Definitely steel frames. Currently own a late 80's vintage purple Geurciotti with Columbus PRX tubing built as a single speed, an '85 (or so) Panasonic Pro Touring , an 83 Trek 760 that needs a new seat tube, and a couple others. All are in the 62-64 cm range. My wife owns a old Somec (Columbus Aelle, Campy Grand Sport) and a early 90's Casati.
