I have a friend that wants to upgrade his girlfriend's all Shimano bike to Campy. It's currently a 9-speed triple. The first thing he wants to change is the shifters and derailleurs. The question is: we've seen both 9-speed and 10-speed Campy rear derailleurs. What is the difference? I know there's a difference between 9 and 10 speed ErgoPower levers and that it's possible to convert the levers, but can a 10-speed derailleur work with a 9 speed Ergo lever and a 9-speed Shimano cassette? (They need to keep the Shimano cogset since Campy doesn't offer a 30 tooth - which she uses quite often.) I assume they will need to use one of those JTek ShiftMates in any case, but are their other things to know about this project?

The thickness of the jockey wheels, ie essentially none.

There are two ways to use Campy shifters with Shimano drivetrain:
1) Put Campy 9sp shifters and Campy rear derailleur. Nothing else has to be changed. This is a well-known working combination.
This is a reasonable thing to do for a person who wants to try the other corporation's shifters. Personally I do not see any reason to "upgrade" anything else: Shimano stuff seems to be more widely available, often cost less, there are cogs up to 34T, and anything else hardly could be percepted in a ride.

If the bike in question has an Octalink crankset/BB, it might be an upgrade to move to a Campy square taper triple crankset/BB the next time the Octalink BB gives up the ghost. But, really, IMO, the shifters are the only other thing worthy of a switch. Everything else is just a "brand name" change, good for talking about, but little else.

Minimal difference in the 9 and 10 speed rear derailleur. The jockey cage plate closest to the spokes is thinner on the 10 speed rear derailleur. Due to the 10th cog on Campagnolo 10 speed being bent towards the spokes so the rear derailleur has to get closer to the spokes to shift to the biggest cog. Limit screws will make either rear derailleur stay out of the spokes and shift to the biggest cog. I use the 9 derailleur on a 10 speed cogset and the 10 rear derailleur on a 9 speed cogset.
Campagnolo has a 29 tooth on its 10 speed. You probably could not tell the difference from a 30 tooth. So unless you are getting into the 32 and 34 big cogs for Shimano 9 speed, that is not a reason to stay with Shimano hubs. Campagnolo 9 speed biggest rear cog is 28 teeth.
I don't think that Hubub works with Shimano road rear derailleurs. It works fine with MTB ones. If you put on Campy 10 shifters, you can keep the Shimano rear derailleur and hub and then shift Shimano 8sp cassettes perfectly. You can upgrade to 9 and then 10 when you need to.

I regularly use Campy 8 rear derailleur with either Campy or Shimano 10 speed cassettes without changing pulleys. The rollers in 8sp have are a smaller diameter and the smaller derailleur body can still shift 29 and 30 t cogs. An 8sp Record derailleur is a find and shifts Shimano 10 cassettes perfectly.

Hubbub works perfectly with Shimano road derailleurs. Both road and mountain ders work on the same cable pull and geometry for the parallelogram.

Yes, use either. Get 10s ERGO, ANY Campag long cage RD(like Veloce), adjust and go ride with shimano 9s cogset and chain, including large cogsets, like in the 30-34t range. I have done this many times, no problem.

Don't road derailers have a shallower angle for the cogset as compared to mtb ones?
