Howdy all, I just pulled my usual stunt and bought this on Ebay first, and am now trying to figure out some history on it. Seller says its an '88 Treviso with Columbus "Tretubi" & Italian threaded BB. Anybody have any more info on the frame? Original status in the brand lineup, the tubing, where it was made, etc? Its going to be a commuter for me. With 130mm rear spacing and Shimano bits on it already, I think it'll be Shimano 9 speed. I just have to decide: flat bar or drops, and what kind of shifters. Thanks in advance for any 4-1-1.
