I just bought a Bianchi road bike at a yard sale this past weekend for $20 and wanted to get a feel for what I bought. It came with 105 hubs front and back and a 8 speed Hyperglide cassette, although I am not sure how original these parts are. The serial number is a different style than what I found so far on google and is 61041328. The bike also has a Compione del mondo Colorado Springs 1986-1987 sticker which it seems they used for a number of years even into the 90s. The bike is a dark blue with grey letters and has Lugged front tube with Bianchi pressed in the crown area. The shifters are Shimano Z-401 which I would guess are original. Can anyone help me identify this bike? Would any info help someone figure it out?
Thanks in advance!
