I'm building my first frame up. Is there a general rule for component interaction? ie Can you use an Ultegra cassette with 105 derailleurs? How about mixing Campy drivetrain parts with Shimano? Aside from hubs, do the chains cogs and hubs interchange?

Most of what you are asking depends on how many cogs you're planning on using on the cassette. A 9-speed Ultegra cogset is compatible with the 9-speed 105 rear derailleur. I think there are mixed results from interchanging 8-speed and 9-speed shimano components, something I have never done. Also, are you going to be using STI shifters or downtube shifters?

As far as mixing campy and shimano drivetrains, don't do it. They are not compatible. End of story.

If you are trying to save money then forget about Campy. The only thing that you could use is a Campy front hub with Shimano parts. Seems that if you look around you can find Ultegra parts just a cheap as 105, but if you already have some parts then you should have no problem with Shimano parts. As long as everything is 9 speed then you are ok with 105/Ultegra or any Shimano mixing.

Generally speaking: Any Current campy group will work across its product range and likewise with Shimano. DONT mix & match Campy & Shimano, its simply not worth the effort & hassle. Campy Cogs and their spacing do NOT equal Shimano cogs and their spacing. That being said... your question is too generic. Yes an Ultegra cassette will work with 105 derailleurs > assuming they are both 9 speed. Similarly a Campy chorus 10 spd cog set will work with any campy derailleurs, again assuming they are both 10 speed. Therefore keep Campy with Campy, Shimano with Shimano. If possible, keep the same model year. Keep the same # of cogs corresponding to the correct derailleur. (8to8, 9to9 or 10to10).

But as far as campy goes they have changed their 9 speed rear derailleur this year for compatibility issues and it is not compatable with previous years sti shifters.
