Gute und schlechte Schnellspanner: Unterschied zwischen den Versionen

There have been reports of a particularly nasty failure mode with the exposed-cam type skewer, related to the radiused plastic washer. If the user isn't careful, sometimes this washer can get rotated 90 degrees, so that the cam presses on the flats as shown in the photo below, rather than sitting in the valley of the curved side of the washer. This creates a likelihood that the skewer can rotate if it becomes loose, so that the cam falls into the valley. When this happens, the quick-release becomes so loose that the wheel can fall out, even if a front fork has "lawyer lips".
