in 1987 Bianchi bought the defunct Legano band and resurected it, supplying bicycles to 1988 Alfa Lum team, with Maurizio Fondriest winning the 1988 World Championship road race. The subject bicycle has a tubing decal indicating 3 CrMo tubes, suggesting it isn't butted and that the stays and forks are lower grade, possibly hi-tensile steel. It's hard to positively identify the drive train components from the low resolution photos but they appear to be entry level. The Saccon brakes don't have a good reputation. The presence of a Unicrown fork and fade paint job suggests very late 1980s to 1990s. I'm not familiar with UK market conditions so I'll defer to other on value but I'd say this is an entry level model.
