There was a time in the late '90s into the early 2000s and it may still be going on but some "Bean Counter" at Bianchi decide that every bike should wear a Reparto Corse (RC) badge. Of course not every bike is a true RC bike and I don't believe this one is. a RC bike would likely have abetter component group but who is to say, I used to know guys who after being given a new SL team frame would take there old Univega or Fuji apart and put those parts on it.
Nice looking bike though
