Ok. So like, if your looking at these. You've probably been looking at carbon bars, or have heard that carbon bars reduce arm pump, but don't want to run carbon and have researched all sorts of alloy and titanium bars. There's one simple question you want answered: Do these help reduce arm pump/fatigue? Yes. Honestly. They do. Deeper analysis; Everyone knows that feeling, after smashing a few downhill runs, of having to peel your fingers off the bars. Unable to hold on but also unable to let go. That is where these shine. I compared them back to back with standard alloy bars of the same sweep but slightly different width. I was able to do 1 sight and 7 full runs, back to back, in 4 hours, before I couldn't hold on to the bars anymore. One week later, with no training or riding between, was able to do 1 sight and 10 full runs in 4 hours. And I could probably have kept going, but it was getting dark. So in conclusion: If you are looking at bars, do yourself a favour, throw down the extra few dollars. Its a few grams heavier but so much better.
