For anyone who really knows what to feel for when they ride, they know why a frame is designed to flex. My issue is this....Cannondales aluminum frames were EXTREMELY rigid, while this did'nt bother the everday trail riders...us racers had complaints, the "lack" of flex on the Dales made them harder to control through choppy corners, G-outs, deep and long whoops, and woods riders had the same ill effects. You don't notice it until you have rode a quad that has the desired amount of flex in the chassis. I'm hoping this chassis is'nt as rigid as the Dales, to much rigidity can hamper handling just as to much flex can hamper handling....it a fine line to stay on.
