Description
Good-quality skewers have acorn safety nuts with steel serrations that can bite into the face of the dropout, so the wheel won’t slip, but most of the skewers have soft aluminum parts in this position, presumably to save weight.
There is a lever on one end of the quick-release, and an adjusting nut on the other end. Never add spacers, washers, etc. to a wheel quick-release device that would decrease the thread engagement of the adjusting nut.
