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.
