XTR short cage rear derailler, 11-32 9 speed XT casette, dura ace triple cranks 30-39-53. furthermore, will this work with 9 speed record ergopower shifters? which front derailler?

you need to use a campy rear derailleur. either a shimano or campy front derailleur is fine, but you lose some trim ability with a shimano front.

You will also need to respace the cassette for campy using a Wheels Manufacturing spacing kit . This is nothing more than a set alloy spacers that replace the ones that come with the cassette. BUT here is the rub, Shimano`s first couple of cogs have the spacer built onto the cogs. The shifting on the highend will always be a liitle off but acceptable for most people ( not for me). The second problem is that you can only use shimano ROAD cassettes. The xt cassette uses an alloy spider to hold the 4 largest cogs that can not be removed. SO it is always BEST to use CAMPY with CAMPY and SHIMANO with SHIMANO. There are to many compromises.

PS Campy cassettes only fit Campy compatible hubs( the same with shimano).

i like the way the ergo levers shift better than dura ace, i like the splined bottom bracket of the dura ace triple better than the square taper of the campy triple (also, the shimano comes in 180mm, the campy only 175mm--i'm 6'5"), and apparently you can only use a shimano cassette on a king ISO hub (on the chris king website it says "For 9spd: Chris set his 9spd Campagnolo record bike up using 9spd Shimano Dura-Ace cogs and chain and it's been working flawlessly. There are also campy spaced spacers available to retrofit Shimano 9spd cogs." should i just go all shimano? would the campy ergo levers work with that? or should i go all campy with a shimano cassette? do i have to use a road cassette, or will a mtb casette work? i'm looking for a bike that will keep up on the road and also climb in the dirt.

my suggestion is pitch the ergo's and buy some Levers (D/A or Ultegra) and some bar end shifters. Shop online and get some deals. All STI's have problems in the grit. Stay Shimano because it suits you and go bar ends

Go one step further and get down tube shfters hooked up to Kelly take offs to keep your shifters near your brakelevers. Kelly takeoffs can be purchased at cyclocrossworld.com.
prob w/ short cageGlowBoy

If you are going to run triple cranks with a 23-tooth difference and an 11-32 cassette, I would strongly recommend against the short-cage (actually "mid" cage) rear derailleur. Most XTRs sold are long-cage, because the short/mid cage takes up less chain and is intended mostly for double-chainring setups.

You can run the short cage, but you'll have to be very careful to avoid big/big and small/small combos. Depending on how long you size your chain, you'll either have (1) only a couple of usable gears with your small chainring, or (2) risk derailleur/dropout damage if you shift into one of the larger cogs while in the big chainring.
