During the JRA test, you can see the aluminum is starting to deform at well under 1000lbs. That's irreparable damage too. All it takes is a small crack and the frame will begin to unravel... aluminum is great, sure, but it's not the wonder material everyone thinks it is.
I think what people are forgetting is that carbon is lighter and rides nicer. It has great characteristics on its own merit. So whether or not it is stronger than aluminum is really a secondary concern. If it is exactly on par, we have a winner. If it is even 10% weaker, then I think the benefits still outweigh the disadvantage. But I don't think that's the case; I'm pretty convinced it is at least on par, or slightly to significantly stronger.
It seem like for carbon to be a winner in most people's eyes, it has to be twice as strong, half as heavy and survive whatever any hack can throw at it. Well, that is not going to happen. Instead what we are getting is aluminum frames that are lighter than their predecessors and they dent easily and all the carbon haters call that progress.
Perhaps aluminum is better at surviving certain situations. But there is little doubt that carbon is better at other situations. End result? Probably a similar overall chance you will break your frame as before, except it's now lighter and rides better. And the carbon V10 costs the same as the old Aluminum one did. I've broken a total of 5 frames including an aluminum V10 and have not yet broken a carbon one, but I will give it an honest try.
