Isomectric head frame - Equalizes the length of main and cross strings in the stringbed, enlarging the sweet-spot for more consistent accuracy even on off-center hits.
Armor Power System @ Top of Frame - Combination of Armor Frame design with distinctive cross sectional shape on top racket's head to reduce the racket's torque and High Speed Frame design with aerodynamic hexagon shape frame to reduce drag on the frame during straight on swing or hit. Resulting improvement on speed and control.
· Wide Aero Frame - Wide Aero design decreases air resistance and combining wide body shape to get solid structure, creates a solid hitting feel and quick swing.
· Reinforced Structure Frame - The new material is adopted in the frame in order to make the frame Ultra high Strength & Stiffness. As a result it can handle string tension of up to 38lbs.
