doubt it as those are boxed bikes from Salsa. The sram stuff isn't bad at all. I'm running X7 stuff on the rumblefish and it's been beaten, crashed and abused...still working. But like a roadie, it's just personal preference to what you like and like a roadie you only need to change the shifters and rearD. XTR shifters are $220, XTR rearD is about $190. Srams high end XO is priced as such as well.

All said, that Horsetheif is spec'd out VERY well for a $2k bike. The fork alone is sold for $900
