The specs are not a secret. I built it up with the following.
Shimano XT rear derailleur and cassette (12x34)
Ultegra front Derailleur
Ultegra Octalink Triple Crank and bottom bracket
Shimano XT shifters
Avid brake levers
Cane Creek S-3 headset
Thomson seatpost
Salsa Moto flat bar
Ritchey comp stem
Wheels are Delgado rims with Shimano XTR hubs (32 spoke)
I believe that is about it. I am sure I am forgetting something. I also put some new grips on there that I found. I tried them on a 3 day, 240 mile ride and they were pretty comfortable. I believe they were call Ergons or something like that.
It rides very well. It is a 62cm so it has 700cc wheels. I am 6'4" and about 200 lbs.
