Hello sc02ma, welcome to the forums. I do not think your Bianchi is rare and there fore extremely sought after (aka valuable) the Bs # is the serial number and maybe Tmar can identify it from that. your pic is too small to see any detail. can you post some better pics? if your having trouble PM me and I will give you an email and I will post them. close ups of the drivetrain, BB area and headtube luggs will help.
what color is the bike? do the derailleurs, cranks, or brakes have any name other than suntour, shimano? are both wheels quick release?
