The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension. 

The NANO TEC technology works by evenly distributing nano-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.

The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.

Based on the design of multi-layered carbon fiber, the advanced Fiber Reinforced System (FRS) can not only improve the elasticity, but also offer stable controllability with high tension string.

ULTRA-THIN FRAME is now 7% thinner than the frame of traditional rackets. This helps to improve the player's swing speed while maintaining the stiffness and torsional resistance of the frame.

Designed by computer simulation, FREE CORE is an innovative form of handles made using nano-nylon materials and molding techniques. It allows players to move more freely, swing smoother, and gives comfort to the hand.

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.
