Li-Ning Windstorm 650: Super light racquet (78-80 gm) of Aerodynamic design with low air resistance and high tensile strength. Increased sweet spot for improved hitting velocity with wider string area to increase bounce strength. Isometic Frame Design. Aerotec-Beam System: With support of advanced calculation system, the rackets are made with extreme low air resistance and thigh intensity to enable the players’ 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.Inner Wave Frame: Top technology and advanced design make force deployed evenly on the frame and lower the air resistance for a stable and prompt return stroke.In order to increase the hitting speed and achieve prompt return stroke, effectively lowering the air resistance would be an optimum approach. The advanced wave design as LiNing rackets could considerably decrease air resistance. During bend molding, the stress concentration points are eliminated greatly and the frame structure thus becomes stable and firm.
