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. 

The technology of the NANO FORTIFY TR + is upgraded with stronger carbon fiber. Not only does it improve the racket's strength and hardness, but it also comes with better durability and handling experience.

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.
