Product technology nano tec the nano tec technology works by evenly distributing o-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame. Seven six 76 the single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life. Hard cored technology inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard. Ultra-thin frame a design breakthroughultra-thin frame is 7 thinner than the frame of traditional rackets, helping improve the players swing speed while maintaining the stiffness and anti-torsion performance of the frame. Free core designed by computer simulation and aided with the adoption of injection moulding technique, this revolutionized handle style allows the shaft to move more freely, which can not only make swings smoother but also improve overall handling experience. Compound-sword the compound frame design can be divided into three major parts the upper section is made with fan-shaped structure to lower wind resistance and accelerate each swing. The compound-sword structure in the middle section is designed to lighten the filler and enable fast rebound. Finally, the lower section is built in airfoil structure to lower wind resistance and keep excellent anti-torsion performance in a whipping style which helps to create steeper and quicker attacks with satisfying control.
