Volkl Energy Box
volkl energy box
Our new ENERGY BOX is an entire system of frame reinforcements made of Titanium and Lite Carbon. This blend of materials has a stable box-shaped geometry on the right and left hand side of the racquet head (at 5 & 7 o'clock). Four graduated ENERGY BOXES with differing strengths on both sides boost the sweet spot to give the tennis racquets an enormous increase in stability.
