The Columbus air tubeset came with a Columbus seatpost. If you don't have one of those seatposts a frameset like this is useless. Personally, I find the frame to be an unfortunate misstep on the part of Ugo and sons. They must have thought the same as they did not make many of these frames. I do however think that frames like this, as well as another questionable design, the De Rosa Tango, are important to show the path taken by the brand over the years.
