no matter what gear anyone here has on their bike they are never going to be able to generate the same amount of torque against that axle as a Pro rider can and they don't slip their QR so nobody here should be able to slip theirs.
I've been wondering the same thing. Why a bolt on an SS/FG and not a QR? What's the reasoning behind it? A bolt is much harder to loosen if you flat, so why is it being used? The OP could have had a problem other than a QR issue, so what about everyone else? What's the reasoning behind using a solid axle with bolts over a QR?
