Old pic: Now has Time ATACs instead of clips and straps.

Pretty much how I had it built up in 2001
Titus Racer-X AL (large) with Fox Float RC
Full XT kit (Cranks are 2004 though) -- I don't like discs
Marz Z2 race (Oil Bath FTW)
Mavic x517/XT with 36 DT spokes
Syncros seat post, easton bar, generic specialized stem
Its just about perfect and only replace parts as they brake.
I used my employee discount on this, saved me a bundle.
My dad has an older one of these. Racer-X's are built like tanks. His is now nearly 10 years old and he bought it used after it was rented by an outfit in Moab for 2 years. Parts were dead, but the frame (and the rear shock) solder on as well as they did th day it was made.
