The brainiacs at ProKennex have done it again. With the new line of racquets comes a brand new technology from their labs. The Force Flow Technology is located in the throat of the frame and will be instantly noticed on court. Designed to redirect escaping energy from the string bed, FFT forces the flow of that energy back into the strings of the racquet, giving you increased power as well as increased stiffness. #1 ranked pro player, Kane Waselenchuk liked the new frames so much he switched mid season to close out his second undefeated season with the KM F175.
