A quick release skewer is the ro, threaded on one end and with a cam assembly on the other, a part of the quick release mechanism, a lever operated cam system used with a hollow axle for securing the wheels on a bicycle. Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing a lever, thus more quickly than wheels with solid axles and hex nuts. On the negative side, a quick-release hub renders a wheel more vulnerable to theft. Also, care must be taken to ensure that the mechanism is properly tightened.
