To make a quick comment on what Beerad is trying to say. "Scientific" tests can be performed in a way to come up with whatever end result you want (to a point of course). The real test is one that mirrors what you really experience while riding. I've ridden with a lot of different bars over the years and can tell you that the 7/8" Renthals don't feel like they flex as much as the Pro-Tapers. In fact, my brother and I bought the exact same bike and I have Pro-Tapers and he has Renthals. When riding back to back you can tell that the Pro-Tapers take a lot of the harshness out of the ride. I swear by the Easton Pro-Tapers and it's a shame their being discontinued. Hopefully the new EVO bar is just as good.
