I never noticed the World Championship decals as being those colors, but you are right! Why are they there? I believe I saw a photo on vintage bikes of another Mancini frame from 2008 (orange I believe) with the World Championship decals framing "Mancini". Could there have been an Italian rider on a Mancini who won the WC, or did the maker just choose those colors for marketing purposes? Another road of detection to pursue. What is with that decal "frame by Ferrari", like it is linked to expensive race cars? I remember reading that internet post about Mancini and I remember the comment about it being a rough ride and the Toronto bike shop dropping it. I must confess, I so lots of long rides on it and I find it smoother than most other steel bikes I have ridden, so I never got that one. The mystery continues.
