Why does my Bianchi Via Nirone road bike have a 6000 series alum. frame instead of the 7000 they advertise?

Question

I dont see the 6000 series frame advertised on the website for the Via Nirone, only the 7000.

Answer 1

Because they put the wrong sticker on it at the factory in Taiwan and it is really a 7000 series?  As far as I know the 6000 Series ALU frame has only been used on their MTB lines.  While the composition of the 6000/7000 alloys differ, both would be triple-butted and the difference might be difficult to ascertain without analysis of the bare frame.

Bianchi is in a bit of flux right now - for the 2007/2008 season they hired a new product manager (from Specialized, I believe) who has significantly changed their lineups.  It wouldn't be too surprising if someone mis-labelled some frames during a change in the product linea.  Given the 6000 series being MTB specific for Bianchi, it seems unlikely your frame is actually a 6000 series.  Then again... Bianchi's US frames are built in Taiwan by a third party, so who knows?

If all else fails, maybe you have a one off, future collectors item?
