Updated pics coming next week:

New build in process - 30mm Carbon Hookless Rims built to Project 321 Hubs, Sapim Laser (Gold \ Black combo)
New Wipperman Chain
A few new ano bits
New rubber

It's only for BB30 bottom brackets, but works only with standard 24mm cranks, so yes XTR will work fine and you won't need any of the SRAM conversion bits.

Not difficult at all.  It slides in by hand and is tightened by two bolts.  It comes with Phil Wood bearings that have been absolutely trouble free.  To adjust, loosen the crank bolt, then loosen the 2 bolts for the bottom bracket, rotate EBB to desired tension and snug everything up.

If you are using a SRAM/Truvativ crank you will need the small adapter in addition to a few BB spacers.  I have my bike pulled apart after the last race for cleaning.  If you would like any specific pics let me know.  I'll probably build it back up this evening.

I'm running mine SS.

FM-056 Frame
Hope Evo Pro II hoops with Arch EX Rim (I have 30mm Carbon hookless rims enroute now...looking at I9 or 321 hubs)
Maxxis Ikon F/R 2.35/2.2
SRAM 24mm crank w/ spiderless AbsoluteBlack Chain ring (32-34t)
Endless Cogs KickAss cogs (17-21t)
EBB by Beer Components (BB30)
VCRC Carbon Post
FIZIK Tundra Carbon Saddle
Race Face Atlas (720mm?) bars
60mm Stem  (can't remember brand)
XT Brakes
ESI chunky grips
SRAM 870 chain?
XPEDO pedals
FOX Float 32 100mm CTD though I also run it rigid with a carbon fork occasionally

The bike has been great and stood up to a ton of abuse.  Only issue right now is what appears to be a slight cracking in the top coat where the EBB contacts the carbon adjacent to the BB but this appears to be cosmetic and is a result of how the EBB mounts.

Not really sure on weight but it was 18ish rigid with bar ends and heavier tires.  Once I get the new wheels mounted up I may try to get a weight on it.

If anyone has any questions regarding running this frame SS don't hesitate to ask.

My FM-056 set up as SS, in it's squishy fork set-up.
