I don't trust it...at all...but living here I see lots of bikes...soo

Carbon bike = .25%...there is one. The BCD. I only saw it cause I knew the rider (by fame and another forum). He is both a freerider and dhiller and djers...smallish guy but super smooth...
carbon parts = 5 - 10% .... seatposts and bars, thats being generous btw I just think there might be some I missed along the way. Oh and on freeriders...none...I don't know any serious freeriders who use carbon anything...(ecept helmets and maybe visors...)

If money was no object I still wouldn't buy carbon. Have seen and heard of too many seriously bad accidents caused by them. Most of the guys I know who tried it, loved it....absolutely loved it...till the carbon breakage occured. Sometimes user error (tight bolts) sometimes after a crash (gauge) sometimes no reason at all. But scary and common.
