yeah, but you have to be pretty rough on it to break a CF fork. Wheelies and jumping stairs could do it, yes. But normal riding on the street is FINE. you never have to worry about a CF fork unless you are doing tricks. You can hit potholes, go over speed bumps, and maybe even have a few minor spills on it w/o breaking it.

Me and my girlfriend have CF forks on all of our 4 bikes and have never had a problem. I know tons of people that have had them for years and never had a problem
