Quote from Nikephorus:
"I think people are too busy arguing materials when they should be arguing workmanship."
I agree with Crum ... this is an excellent point.
I will say to the OP, that while I am generally ignorant on the subject, my fear/mistrust of Carbon Fiber frames comes from my inability to fix them, or have others fix them at a reasonable price. Warranties aside, i haven't been too impressed with the stories friends have told ...
(and for me, the frame will eventually take some sort of hit, be it from a car, a wreck, tripping on the steps while carrying it, etc. It's only a matter of time before i'm trying to work out a dent)
