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

Combining the controllability of “diamond-shape” structure with the stability and smoothness of “sword-shape” structure, AERO-DIAMOND frame minimizes air-resistance and improves handling stability during each game. 

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.
