never heard of them, my bike certainly doesn't have them - but I think it had some annoying washers with a bent tab that somehow was designed to stop the wheel coming out ? anyone know what I am on about ?
My commuter, an old 90's rigid MTB, is like that, had hooked washers but no lips. I put a pair of qr wheels on it when I fixed it up and they are proper quick release at the front and back.
My road bike OTOH has the bleeding things on the front and there's always a couple of minutes of faffing about to get the correct tension every time the wheel comes off.
