the only carbon that has proven itself to me are easton carbon bars, i dont like carbon fiber because it is tempermental persay, after it is scraped/chiped/whatever, it is worthless and stuctually unstable, as for the components theyre from a reputable brand, but they are low end. as for the fork, no no no, stay away from sr suntour, they suck huge ass. i also dont like the look of this auction, the title and description list the fram as giant, but the name on the frame doesnt match, and i dont think giant makes an all carbon frame. i would look into a specialized hardrock, or something similar instead.
