from what I've read in other "what bianchi is this" posts, I have deduced that this is a medium-low end model made in the late eighties (also based on the components and the lack of existence in the 81-86 catalogs). can anyone corroborate this?

i will be replacing the rear wheel with a fixed wheel and possibly the cranks/chainring. can anyone comment on what type of bottom bracket may be inside, in case i need to get a cheap crankset for the winter?
