Seems to be a lot of your name brand companies. My point is that most of the brands today are made over seas to spec. The overseas manufacturer can take a design and tweak it slightly and sell it them selves. I ride MTB as well and there's a big thread on MTBR.com about carbon 29er frames, people love em and many have ridden with no ill affect.
Anyway, just wanted to post the original post for people wanting one.
