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 offer racket excellent shock-absorption and enhance handling in every single 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.
A breakthrough from traditional hexagonal frame—different types of frame structures are integrated into the upper, middle, and lower parts of the frame based on the racket setting to optimize stability and swing smoothness. Hard Cored Technology is also tailor-designed to meet the needs of different frame types, enabling greater stuffiness as well as elasticity.
