The Power Arm is designed to be free-moving upon the string bed contacting the ball. The Power Arm then moves together with the string bed giving more energy to the shot for maximum power.
Power Arm racquets, while designed to be the most comfortable and powerful racquets in the Volkl Tennis line, also have great playability. That playability comes from the combination of effortless power and the added bonus of amazing spin potential which enhances most player’s control.
