There is a specific Jtek adapter to let you use 10-speed Campy brifters with a 9-speed Shimano cassette and derailleur.
If I do decide to upgrade to 10 speed using the conversion cassette, can I retain my Ultegra Open Pro's or are these among the wheels that are incompatable with the AC conversion cassette?
It'd be a shame if not. I love my Open Pro's!
Check with AC. I certainly don't see why anything as common a Ultegra hubs wouldn't be useable. Also, you could use a 10-speed Shimano cassette and just get a different Jtek adapter. I'm sure this would be much less expensive than the conversion cassette.
