well for what its worth now, bettrenever than late perhaps?
I have a bianchi via nirone xenon, because I prefer campag, and its in white, and has been very reliable.
I upgraded the wheels not because they needed changing but I needed new wheels for my winter bike so used the ones off the bianchi and changed those to fulcrum racing 5's. Saddles are a matter of personal choice but for me the san marco original was painful, so changed that, Zaffiro tyres are hard wearing but not great in wet IMO so changed those too. White bar tape gets dirty in 5 minutes so that's black now.
The rest is original though and it's good enough for me, done about 4k miles so far no problems.
