Racket Pro Kennex

This frame is a 60% graphite and 40% fiberglass mix with a foam core. Low vibration. Grip size is 4 1/2. One of the first rackets with the principle of “Kinetic System Technology”, patented by the Taiwanese company “ProKennex” (created in 1978). Only in their innovations, micro-balls in the frame move not in the longitudinal direction, but in the transverse direction in micro-compartments along the entire cavity of the frame rim. During the contact of the racket with the ball, the balls move forward, increasing the impact force, and in the period after the shock vibration, the balls reduce its amplitude and duration.
