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

PYROFIL carbon fiber and its composites, are advanced high-performance materials from Japan. The characteristic of high intensity bonds ultra-light offers racket excellent shock-absorption and enhances control.

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. 

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.

The introduction of nanotube material can effectively improve the strength, elasticity, and anti-fatigue performance. The lightweightness also ensures a soft feel to the grip.
