Abstract
A quick release camming mechanism is used in a bicycle skewer that secures a hub to a fork. Whereas prior art quick release mechanisms have only a single lever, this mechanism has two independent levers. About half the force is required to independently push either lever closed as to push both levers closed simultaneously. Similarly, about half the force is required to open either lever individually as to open them simultaneously. A similar quick release camming mechanism also works well for a quick release seat post clamp with similar advantages. The present invention is not limited to use on bicycle components.
