Here is another one of my bikes.
A 1972 Hetchins 6-day.
I have a track setup for it with Fiamme Ergals and Cinelli track bar and stem, and have it set up this way for road use, with proper Weinmann 27" wheels and Cinelli road bars with brake attached. Even the red tape is vintage Schwinn plastic tape. See the rest of the pictures at www.hetchins.org/504sixday3.htm. Note the fluted seat tube in the one pic.
