What are the disadvantages to a carbon frame?

[Eden]

I stand corrected - I was looking at an old F1 car frame that was aluminum. It does appear that current cars have a carbon monocoque chassis/cockpit. They are specially coated so that they will not splinter in case of an impact, something which obviously bikes don't have, but I would guess flying carbon bits aren't going to be a huge problem in bike crashes either.

I don't know about bike snobs bike… that sounds unusual of not improbably, but the carbon part I have seen break without provocation was carbon spoke wheels.. which had a bad habit of simply shredding themselves
