A quick release skewer is a device that secures a bicycle wheel to the frame or fork using a lever and requires no tools.
You must release the lever to remove the nut of the skewer and pull the wheel off immediately. It comes in handy in changing wheels in racing bikes or transporting bikes. Tightly fitted skewers secure wheels when cornering and braking. For lightness purposes, there are some models boasting alloy end caps and hollow axle. Quick-release assists in speedy pit-stop repairs and ensures wheels secure and in a good condition on practice rides and competition.
