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. 

Introducing the TORAYCA®PREPREG material from Toray, a leading carbon fiber manufacturer from Japan, NANO FORTIFY TR not only upgrades the elasticity and impact resistance, but also enables excellent exercise performance, which further provides greater repulsion, easy-yet-smooth shot-making, and advanced racket-handling experience.

The excellent shock-absorption and malleability of the materials keep the frame both elastic and durable in the face of deformation under tension, and also disperse the stress and improve shock-absorption performance at the same time.
