Gute und schlechte Schnellspanner: Unterschied zwischen den Versionen

There are scuffs on the dropout faces in the photo below: the quick release was loose, and the wheel moved around in the dropouts, despite the "lawyer lips". Also note the uneven depth of the scuff marks. These cheap dropouts, formed by crushing the ends of the fork blades, do not have perfectly flat surfaces.

No secondary retention device secures the wheel as well as the quick release itself. A device which relies on the skewer to hold the wheel offers no protection if the skewer breaks.
