GEWO Flexxon - Table Tennis Rubber The new star of the GEWO range is the Flexxon OF+! It has the most progressive technology ever produced by GEWO. The new high-tension, dynamic sponge provides the player with great tension- a perfect balance between speed, elasticity and control. Flexxon is the fastest of the GEWO rubber, created especially for the topspin player who wants a fast rubber with a minimum loss of control. The progressive, tacky surface-structure provides a longer dwell time on the ball giving spin and control. The high-tension rubber surface further enhances the spin while adding speed by means of it's catapult effect. These factors work together to produce a spin ball with a strategy which is extremely difficult for the opponent to control. Rubber for intelligent spin and speed variations Recommended for high-performing players who enjoy an offensive, attacking game.
