well it looks like you have an Athena brakeset and a nice Campi? crank just go from there. what are your wheels? it looks like that was offered as a complete Chorus or a frame/fork. personaly I would put it back together and enjoy that great Bianchi ride.
OH I often think about updating my '90 Proto (from the Reporta nel Corse) but then look at it and why? she rides like a dream everything works and she actually somewhat of a classic. and besides according to those posts about that specialized and trek bikes steel and DT shifters look to be back in style
