Hub Skewer
A replaceable part ofmetal rod with a hubclamping mechanism that attaches the hub/wheel assembly to the fork or frame. SomeMany skewers are equipped with a quick-release mechanism that allow removing the wheel without tools, facilitating changing a tire, putting a bike in the back seat of a car, etc. Unfortunately, the trade-off for easy wheel removal is that it's easier for thieves to remove a quick-release wheel. Skewers without a quick release will use a hex or Torx wrench for removal. It is also possible to secure the wheels with axle nuts, many of which use a crescent wrench of appropriate size.
