Aksiums are some strong wheels. I was riding my CX bike down a gravel track at about 18 mph when it abruptly ended into a boulder field that was cleverly disguised by some very nice looking grass. I was on the tops and couldn't risk moving my hands to the brakes, so I had to ride the whole thing out. My front tire immediately exploded. The uncushioned rim bounced from rock to rock as the seat rammed my nuts, and then the front rim wedged itself in a crevice and sent me flying over the handlebars. It was a real shame no one was there to witness, because it must have been hilarious. Anyway, my Aksiums weren't even out of true. Only the tops of the rims had some small dings.
