The STIGA Evolution racket introduces an exciting new technology in the Shock Dispersion Tube. This new SDT technology utilizes a high-tech composite rod that is integrated into the handle and blade. This tube allows energy and vibration created from contact with the ball to be transferred through the tube and out of the handle in the form of sound energy, which improves speed, control and feel. The STIGA Evolution offers performance ratings of speed 96, spin 94, and control 90. The racket features ITTF approved rubber for tournament play.
