Abstract
The shaft of the tennis racket is split between the handle and the head into two basic parts, so that a first part cantilevered from the grip supports the head, preferably with a journal, at its inner end while the second part supports the head at its outer end, preferably with a journal. The two shaft parts are unconnected so that they will flex independently of each other to maintain the head generally parallel with the axis of the grip independently of the force or positioning of the ball on the strings of the head. The shaft part that is connected between the grip and the outer end of the head is removable or displacable from the head to allow stringing of the head, and reassembly to overlie and protect the string holes along the side of the head.
