The NANO TEC technology works by evenly distributing nano-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame.

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. 

Different frame structures—including POWER-BOX, DIAMOND, AERO, and AERDYNAMIC—are rearranged and integrated based on computer simulation to optimize the hitting, frame characteristics, and overall performance.

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.
