Converting 9-speed Campag to 8-speed?

These may well be stupid questions, but I'm new to this:

I have 8-speed Campag Avanti/Mirage stuff, from 1998. Mostly good, but I don't much like the shifters and derailleur. I have a chance to buy 9-speed Record ergo shifters and rear derailleur from the same year -- some seem to suggest that I can easily make the new shifters into 8-speed, by changing an internal gear? Where would I find one, and is it expensive? (And does anyone here have one?) Perhaps I could take it out of the Avanti rear shifter, and transfer it?

How about the 9-speed rear derailleur -- will it work with my 8-speed cassette?

Another option is to put a nine-speed cassette on the back -- can I do that without changing the hub?

Lastly, I take it there will be no problem with the front shifter: should deal nicely with a triple derailleur, no?

(Just bought a 1998 Bianchi Eros, and I love the steel frame, but some of the components are a bit sub-par.

Oh, and another question: anyone know if cross tires will fit on this bike? I'm off to a bit of Mexico where the roads aren't so wonderful...

You can change the Record 9 speed ergopowers to 8 speed. You will need part EC-RE060. If I remember correctly, the Avanti used a different system, so it may not fit. Branford bikes, probably other bikeshops also, sells the part ($55):

I did it a few years ago and it took me half an hour.
The 9 speed derailleur should work ok with an 8 speed cassette. If you have a 8 speed rearwheel now, you can not put a 9 speed cassette on it.
The front shifter will be fine.
Good luck

Thanks! The Avanti I'm told has the same innards as Mirage, and I think perhaps even Chorus. So I'm going to take my chances...
