Hello i bought a Bianchi Campione Del Mondo 1986-1987 Colorado Spring from a homeless guy for 2 dollars. I didnt really knew it had some value until i checked it up on ebay today and i saw some Bianchis for some high price. I been using this bike on a daily basis until now. I didnt see any bike like mine on ebay so i would like to know its aprox. value. This bike has everything original even the seat. I would like to know is history of the bike if anyone knows something let me know thanks alot!!!
