The Wilson K Factor K One FX Tennis Racket
The Wilson K Factor K One FX Tennis Racket is the flagship racket of the new K Factor line with the brand new and improved FX Technology. This system splits the traditional throat beam in to a quad shaft; two split forks on each side. The benefit of this is to reduce the vibration that passes through the frame in to the arm, thus improving the players touch and feel. It also reduces the stress on the arm and the chance of developing tennis elbow.
