Aerotec-Beam System: With support of advanced calculation system, the rackets are made with extreme low air resistance and thigh intensity to enable the playersâ€™ performance in various ways.The rackets fit into different players are all resulted from aerodynamic design. Through unrelenting tests, and the strategies that targeted at different playing, the supportive data is accumulated, LiNing beam system is thus established. Dynamic-Optimum Frame:All-round optimized design improves racket mechanical structure for more efficient attack and defense system.Apart from further increase of sweet point based on isometric frame, the sweet point extends upward and the hitting point is moved higher. The effective defense area is enlarged for severe drop shot and a dropping strength that bursts in a blink. The hitting velocity is improved considerably with widened stringing area and increased bounce strength.
