Teknologi Karet Butterfly

High Tension technology enhances the reaction of the playing surface by adding tension to the rubber molecule itself. Like a coil spring, the Spring Sponge absorbs the incoming energy of the ball and releases it as additional power for the player’s own shot. Rubbers with Spring Sponge technology enable shots with high amounts of spin.
The base of the top sheet is very thin, visible to the naked eye. The rubber compresses and the surface is depressed by the ball on impact; thus enabling a high degree of rotation to be imparted on the ball.    Easier to impact than conventional Spring Sponge and with an improved rebound the new Spring Sponge X provides the increased feeling of holding the ball on the racket and enables to arc the ball even better, creating more spin and powerful shots, all with a total weight reduced by about three percent, compared to Spring Sponge with the same hardness and thickness.
