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. Benefits: Colorful design shaft, Pro Master, Carbon fiber material, Quick handling and fast moves Racquet Technology: Air Stream System, Bio Inner Cone, TB Nano, Wing Stabilizer, Stabilized Torsion Angle, HB Shaft, Dynamic Optimum Frame, Aerotec Beam System Bio-Inner-Cone As a breakthrough to the traditional shaft, Li-Ning has originally introduced the cone-shaped racket shaft design with patent. By moving up the bending point of the shaft could increase flexibility of the racket, enhance controlling feel, and empower athletes to express their intentions more clearly and perfectly. Air-Stream System Li-Ning’s patented technology Air vents are reserved at points 5 and 7 o’clock of the racket frame so that air can pass smoothly through the racket frame, which reduces air resistance and enhances swing speed. Aero Tec-Beam System With support of advanced calculation system, the rackets are made with extreme low air resistance and high intensity to enable made with extreme low air resistance and high intensity to enable the player’s performance in various ways. Based on Aero Tec-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 player’s performance in various shots. 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.
