TSP Agrit Speed is the new high-end product with integrated "Dynamic Tension" technology for all-out offensive players. Compared to the regular Agrit, the new somewhat harder sponge "Made in Japan" with the "Dynamic Tension" technology provides a never before experienced spin- and speed feeling. Agrit Speed is conceived for players who are playing an all-out topspin game and who need maximum speed by every shot. The energy transformation has been optimized, that means even the energy of the toughest balls can be converted into speed and rotation. TSP Agrit Speed ? Quality "Made in Japan".
