Isometic Frame. UHB Shaft:State-of-the-art technology combined with real data collected from playerâ€™s practice, optimized shaftâ€™s performance through continuous improvement.Based upon bionic study results, ergonomics and trial data collected from top professional players, the racket shaft with frontal bending point is accomplished. A great improvement in smash performance â€“ especially in drop shot, was made by the featuring of low wind resistance, high flexibility & strength. 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. High Carbon:The rigid carbon fiber is used to decrease the racketâ€™s weight and improve its strength for easy control.The carbon fiber helps decrease frame weight considerably and ensures higher strength and rigidity. Using such material in LiNing rackets makes practice easier for novice players.
