Wilson K Factor technology











    The next generation of [K] Factor tennis rackets is called FX which means, [K] Factors multiplied. It utilizes a "Quad Shaft" construction in the throat area of the racket with improved distribution of weight. Quad Shaft means the throat of the racket has 4 shafts vs. the conventional 2, which ultimately means more stability. This technology provides the racket with 23% more "torsional" stability and more evenly distributed mass resulting in more control
    WHAT IS [K]? The [K] represents the four new proprietary technologies which result in enhanced [K]ONTROL.
    [1] [K]AROPHITE BLACK The older nCode technology at the molecular level filled silicon dioxide between the carbon fibers of the racquet frame to stiffen and strengthen the fibers. Karophite Black is a proprietary technology that goes beyond nCode. It is a lattice of tiny fibers that mixed with the silicone dioxide which actually connects and binds the carbon fibers. This makes the racquet frame about 40% stronger and stiffer than an nCode frame. The result is a stiffer head for less distortion on hits and better control. This strength and stability also gives many unique design options for the yoke, handle and other parts of the racquet, this permits some of the other technologies described below. [K]Arophite Black technology is used in all [K] Factor racquets.
    [2] [K]ONNECTOR, 2 external wings molded into each side of the hoop to increase the dwell time of the ball upon impact. This provides greater control and comfort with a larger sweet spot.
    [3] [K]ONTOUR YOKE,new frame engineering technology that enhances stiffness at key stress points on the racket for improved torsional stability.
    [4] [K]OMPACT CENTER, new industrial design innovation that improves handling, maneuverability and provides additional feel. Directly inspired by #1 in the world Roger Federer.
