Help Identifying a Vintage Bianchi
I recently purchased a vintage Bianchi and I'm having trouble IDing the model. I searched for a serial number but couldn't seem to find one. All I know is that I'm pretty sure it's 80s or thereabouts. I also just joined BikeForums so can't post pictures yet, so I'm not sure the best way to go about this? I can list out components if that would be helpful? Thanks!

Welcome! Description might help; color (be specific on shade/metallic/etc.), frame stickers/decals, components, things like that.

It's likely one of the early 1980s, Piaggio era models, with the serial number stamped on both sides on the seat lug.

That seems right? I saw a stamped in 1940 on the left side and 3 A on the right. I don't know what this means though
The bicycle has be largely rebuilt with newer componets over the years. The crankset, derailleurs and wheels are replaccements, complicating identification. However, based on the presence of dropout eyelets, it would appear to be a lower, mid-range model, possibly a Nuovo Racing. To confirm the level, please report the seat post diameter, which should be stamped on the back of the seat post, at the top of the barrel section.. |

Your frame was manufactured in Italy during January 1983, so it is Piaggio era. However, it is misssing the Piaggio decals, so it may be a repaint and re-decal. Unfortunately, Bianchi did not encode model information into their serial numbers.

Given the size of the frame, I was expecting 27.2mm but it could be slightly undersize due to a distorted seat tube or being an owner replacement. Regardless, it indicates the frame is high grade tubing for the main tubes. The presence of dropout eyelets suggests a lower grade steeel alloy for the stays and fork blades. In 1983, this was typical of a Bianchi Nuovo Racing, which used a Columbus SL Tretubi tubeset, so that would be my leading candidate.
