is there a 'B' on the DT/HT lug or Bianchi or something on the ST caps or forkcrown? again to me the 105 kit (esp index) and serial # on the headtube do not match up. also the wheels are certainly a later addition. do you think the black was the orginal paint? the person you got it from has no idea?
if the black and the parts are orginal than it may be an '85/86 brava.
