HDF: Shock Absorption: High-tech light shock-absorption materials filled in racket frames, improving smash performance and avoiding injuries from movements.
UHB: Shaft State-of-the-art technology combined with real date collected from players' practice, optimized shaft's performance through continuous improvement.
TB: Nano Powertec The application of nanometer technology upgrades the rackets' manufacturing process in an all-round way and thus breaks the limit in hitting intensity
Wing Stabiliser: ultra elastic 3G titanium alloy is placed on the head from 9 to 3 o'clock to reduce vibrations and increase torsional stability for improved control.
Free Hole: strings are closer to the frame for greater repulsion on impact. Also the sweet spot is increased by 20%.
