Abstract: A crossbow including a riser, a limb coupled to the riser, and a cam assembly rotatably coupled to the limb about an axis of rotation. The cam assembly including a string guide defining a plane of rotation of the cam assembly about the axis of rotation and structured to support a drawstring, a drawstring attachment point structured to engage the drawstring, a power cable journal extending away from the plane of rotation along the axis of rotation and structured to support a power cable, and a power cable attachment point structured to engage the power cable. The power cable journal is shaped to displace the power cable away from the plane of rotation as the crossbow is drawn from a released configuration to a drawn configuration to provide a gap sized to permit the drawstring attachment point and the power cable attachment point to pass between the power cable and the plane of rotation.
