...it's more on the model of a "sport touring" bike. So longer chainstays and longer wheelbase, that allow for more flexibility in selection of wheels and tyres. Also room to mount fenders. IME there are not a whole lot of Columbus tubing touring bikes around. Generally speaking the Italians (who used Columbus) didn't manufacture and sell very many of them. In Italy, when I was there for a while, if you tried to talk about touring on a bicycle the Italians would look at you like you were nuts. I think maybe
the Schwinn entries from the 80's might have a Columbus entry, but those were made mostly in Asia.
