[K]factor is the combination of many different components working together within the racquet. Wilson claims these new technologies are going to revolutionize control in the game of tennis. World #1 Roger Federer contributed some invaluable input concerning the design and performance of these frames. The [K]zen is the leader of the "tweener" racquets from Wilson. These racquets are more forgiving than a heavy players frame (like Federer's racquet) but less powerful than a game-improvement racquet. Faster swinging intermediate players will love that control and stability from this racquet. | Specifications for: Wilson [K]zen 103
