Campy Compatibility

I currently run campy Centaur and desire to gradually upgrade to either Chorus or Record. Are the three groups compatible? Is it possible, to say, purchase a Chorus rear derailler and run with the other Centaur components?

Yes. I've mixed & matched & had no problem. This is just my experience, so don't take it as gospel.

Yes, as long as all the components that are "speed" sensitive, like shifters need to match # of rear cogs, then everything will work together from Record down to Xenon.

You will have no problem, as long as you don't do things like mixing 9 and 10-spd. shifting components or Centaur and Chorus crank arms without changing the bottom bracket. My only comment is that you probably won't notice any improvement in your shifting should you go from Centaur 10spd. to Chorus or Record (IMO).

If your Centaur RD is '03 or older, upgrading that to a newer Centaur can give improved shifting due to the newer mechanism (identical to Chorus without the carbon bits).

Chorus and Record shifters have ball bearings instead of bushings...slightly smoother.

Personally, I'd tell you to leave it alone as there is scarcely any difference...

As for the crank and bottom bracket, there is a fairly large difference in weight of the bottom bracket, and you get a narrower q-factor with chorus and record. If you only want to save weight, you can replace your AC-H bottom bracket with the new '05 Centaur bottom bracket.

Thanks one and all for your help. In reference to the '05 Centaur bottom bracket. It appears different than the older model in that the crank side does not appear to have two pieces ie a cup on the crank side to slip the bottom bracket into.
