It is newer than my 1981 model, probably mid-1980s. I was curious to see an Italian frame with Japanese components, having previously seen either all-Italian or all-Japanese Bianchis.
52-42/13-23 was very typical stock Bianchi gearing during the 1980s. I changed mine to 50-42/14-16-18-20-23-26, which eliminated the redundant ratios while providing a useful bailout low gear.
