ABSTRACT:
A quick release camming mechanism is used in a seat post clamp that secures a seat post to a seat tube. Whereas prior art quick release mechanisms have only a single lever, this mechanism has two independently rotatable 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.
