In my opinion, and this is just from what I know of current component offerings and those I've used, this would be my component selection if I were to build another FS bike from the ground up:
1) Brakes - Shimano XT or XTR
2) Shifter, Cranks, Bottom Bracket, Chain, Rear Derailleur, Cassette - SRAM XX1
3) Fork - Rockshock SID World Cup w/remote
4) Rear Shock - Monarch XX w/ XLoc Full Sprint remote (locks both front and rear)
5) Wheels - Chinese Carbon Hookless 30mm
6) Seat - WTB Laser
7) Bars & Seatpost - Chinese Carbon
Frame - Chinese Carbon of your choice
9) Grips - Thinking I might try some Richey WCS Foam (or similar)
10) Tires - GEAX Saguaro or Maxxis Ardent
11) Pedals - Eggbeater 3 or Ti
12) Stem - Easton EA90 or EC90 or Thomson Elite
13) Headset - Order with the frame or Cane Creek brand
14) Seatpost clamp - Thomson Elite
15) Cables come with the shifter
16) Grease - Park Tools Polylube or similar
