Looking at the info from the Used Bike Buyers Guide, it appears the Super Strada was made with different tubing over the years, which isn't surprising as models tended to follow the trends in available tubing. I don't know enough about how to distinguish an Italian-made Univega from the others, unless it has Italian threading. Anyway, here is what is in the guide on this make. Lou Deeter, Orlando FL 32819
