This is a picture of my Sport DLX that I recently sold (replaced by the Pro Tour 15 listed in a previous thread). I purchased it new and it was my main ride until it's replacement with the Pro Tour 15. Serial #80703113. The frame was made in Taiwan. Seamed Tang Infinity,butted main tubes with Hi-Ten fork. Shimano AceraX derailler. Exage cranks. Weinmann wheels. Based on T-Mar's research on Sheldon Brown's site, I have it dated as a probable 1985. Which is about when I purchased it from The Ski Station, State College, Pa.
