There is a 54 cm Bianchi, listed as early 80's I just bought on ebay. The photo of the Columbus tubing sticker is hard for me to read. It is some kind of Bianchi Columbus tubing with nice lugs. Any idea on the age of this 12 speed and the kind of Columbus these bikes were made with? ( I paid $172.00 for it, so I guess this qualifies as a bargain).
