The frame is basically static and holds the driving force of the racquet - the strings - in place. The strings are attached to both sides of the frame. Only some strings are active when struck by the ball. This means that racquets do not deliver their full potential. Babolat set out to imagine a racquet optimizing the frame and the strings - to invent a frame which permits all the strings to work together to their full potential when striking the ball.
