Identify this bicycle: Bianchi
This is going to be a 1973-1975 Bianchi 10 sp. I am able to choose the dates based off the logo used. To me it looks like a Special. However it seems you do not have a lot of the original parts, as this would have come with Campagnolo parts, and unless you are lucky,I am going to guess, those still aren't on this bike.



This is the 1973 Bianchi catalog. I choose the model over any other that look similar because of your "rack attachment" this is the only model sold in celeste that had a fender mount. I am also going to say it isnt 1973, because the fork crowns were all chrome in 73, so most likely a 1975, or you have a non original fork.
