So I've got a vintage Bianchi that I'm trying to identify so I can sell it. The bottom bracket has 4.0 102 stamped on it, but I don't know if that is a S/N since it is different from what others report on S/Ns. The bike is metallic blue. Also it has a Piaggio decal on it. Unfortunately the only other decals are the Bianchi decals on the bottom tube up to the steering head. I wonder if it is worth taking to a shop to get appraised.
68mm Bottom bracket
Suntour Shifters and Derailuers
Campagnolo gears and arms
After a little more looking on www.bulgier.net I think I found that this is a Sprint/81 based on the rear axle frame work.
Can anyone confirm this? Or better yet does anyone have pictures of their sprint/81?
Any other good info for better ID? Thanks for any help in advance.
