Carbon parts are also known to fail catastrophically without any warning if they have been compromised by a gouge that you may not notice for instance. That's why experts most emphatically urge anyone who rides a bike with a carbon frame and or fork to inspect it closely before any ride.

Sound advice of which a few us us have pointed out to him. I didn't know that carbon fiber was so prone to failure like you mention. I, for one, will steer clear of the stuff. Like what Ozonation pointed out-- it's not going to make a difference with weight issues unless he's racing, and that isn't exactly the right bike for that. I hope you are taking note of all this keyven. We don't want to hear back from you saying that you got injured. I hate saying
"I told you so".
