[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]four 112 has a nice amount of control considering its high level of power. Playtests found this frame to have great feel in addition to nice shock dampening stemming from the [K]onnector wings on the sides of the head. | Specifications for:
