I have the Via Nirone C2C frame with the 105 setup & celeste frame. The more I ride it, the more I like it.
I previously rode a 1998 Trek 5000 with Campy Veloce. With the Bianchi, I am impressed with the better balance. It is much more suited to the way I ride now, which is mostly recreational. The geometry is a tad more relaxed and comfortable. The cons, which are minimal are; the bike is a little heavier. The Aluminum frame (even with the carbon seat stay and fork) offers a little firmer ride. I am by no standard an expert, just my 2 cents.
I recommend highly as long as you are not expecting a racing bike. As always, ride it before buying.
