ProKennex Kinetic Pro 5G Classic Racquets Technologies
Kinetic System Technology
Thousands of micro-bearings are housed inside chambers around the racquet head. As the racquet swings forward, the micro-bearings move to the back wall of the frame, loading energy. When the racquet strikes the ball, this kinetic mass transfers forward, adding power and reducing frame shock and vibration.
