I have a Wander Track bike. The date in the serial number indicates a manufacture date of May 1961. I bought it used in 1968, it had Weinman alloy cottered track cranks, steel track dropped bar. I chromed it in 1970, put campagnolo cranks, durace brakes, shimano rear and campagnolo front derailleurs, campagnolo hubs, changed the campagnolo downtube shifters to campagnolo bar end (fingertip) shifters. The frame uses Mannesman tubing from Germany (the original double butted tubing manugacturer). Frame measures at 24".
Carbon is light but steel has the feel.
