did you buy the bike in the link? or a different bike? the one in the link looks like a Torquise with white decals.
the bike in the link looks like a '87 Brava with a Tange DB chromoly main frame, mangalloy stays and chromoly fork. great riding bike. it would be a bit older than 8 years more like 21ish
the Campion del Mondo sticker has nothing to with the model or value of the bike. that sticker simply commerates a Bianchi being ridden to victory at the '86 world championships.
$280 is an OK price depending on condition. better pics?
