Isometric Head Shape - Equalizes the length of the main and cross strings in the stringbed, enlarging the sweet-spot for more forgiveness and accuracy on off-center hits. Nano Technology - The application of nano technology helps to improve the stiffness and rigidity of the frame. The end result is a stronger and more stable racket, with less torsion and vibration Armor Speed Frame - Triple dimension armor strengthens and stabilizes the frame. In addition, its low wind resistance increases racket swing speed. It shortens the timing of contact between the racket and the shuttlecock.
