The short cage XTR rear might not work with that 34 tooth cog other than that you'll be fine.

The shorter cage derailleur will work fine with a 12-34. Only functional difference between mid and long cage is takeup capacity (34 vs. 44 teeth, if I remember correctly). Since your front difference is only 12, you should just make it.

Why not 12-25 or 12-27 ;better ratio; better shifting;Why not 38 in front?
uhh.... maybe because they want lower gearing for real hills nmWriConsult

For trail riding a 34 cog would be nice but IMO if you are racing and you need more than a 39 front/27 rear combination you should be off the bike and running.

Sorry, I'm new to this particular forum and didn't realize it was quite so racing specific.

As with all things bicycle, the answer depends on what you're using the bike for. If the guy is going to race it I'm sure you're right. But people DO use CX bikes for trail riding - this weekend I went for a rare snow ride in Portland's Forest Park, and two of the dozen or so other bikes I saw out there were cyclocross. At least one of them was definitely spinning uphill on a gear somewhat lower than 39:27.

No need for apologies my friend. I agree with you 100%. If you don't race your cross bike trail friendly gearing is a great thing to have. I rarely ride my mountain bike anymore. I just love hitting the trails on my cross bike and there have been plenty of times when I wished I had something bigger than a 26 cog.

Yes I think I saw a Bianchi Axis at the local shop with an identical setup, only w/ RaceFace cranks and an XT derailler. I am running a 12-32 8-speed w/ 28/36/50 chainrings (Sugino 74/110 BCD) and it works great. I have raced CX with it, and can pretty much leave it in the 36 the whole time, although I am a not-very-fast B. I use all those gears on the steep-ass hills around here also.
