Ultra-Carbon Made of ultra strong material, the racket has optimum rigidity to bear higher tension for exact and steady strokes. The racket made of ultra rigid carbon fibers with higher strength and rigidity, sustainable for more string tension, and reducible to the risk of frame deformation.The rigid carbon fiber is used to decrease the weight and improve its strength for easy control. The carbon fiber helps decrease frame weight and ensures higher strength and rigidity. High Tensile Slim Shaft The top slim shaft design provides extreme strength and easier free control. The 7.0 mm top slim shaft design provides extreme strength and easier free control. Perfect balance with racket weight and moving inertia and aerodynamics. High tensile slim shaft as the mainstay of power and skill, strictly and precisely release the intention of players, in a cohesive state of racket and the body. Dynamic- Optimum Frame All-round optimized design improves racket mechanical structure for more efficient attack and defense system. The sweet point extends upward and the hitting point is moved higher. The effective defense area is enlarged for severe smash by dynamic-optimum frame. The hitting velocity is improved considerably with widened stringing area and increased bounce strength Aerotec Beam SystemBased on aerotec beam system, support of advanced calculation and gathered practicing data, the structure and shape of rackets frame section have extreme low drag coefficient and high intensity, to enable the players´ performance in various shots.
