Easton carbon bars are reputed to be stronger than alloy equivalents?
Well, technically, ALL carbon bars are stronger than their equivalent alloy bars.
Carbon is ALWAYS stronger than equivalent metals. Now, what does decide if it breaks or not is impacts, dings etc. As long as you don't knock anything against the carbon it will remain stronger than metal, but all ya need to do is knock somehting on the bars (even a small tree branch can cause enough damage to lead to catrastrophic failure (damn spelling that word).
Reason why carbon forks and frames hold up so well. They are stronger as iron.... but only as long as the frame gets 0 impact on it.
3 things I stay away from... carbon seatposts, carbon bars, carbon crown'd forks (like the new rock shox w/ carbon crown and steer). Other than that, a carbon frame is more than ample etc. Think BCD :0
