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.

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 AERODYNAMIC—are rearranged and integrated based on computer simulation to optimize the hitting, frame characteristics, and overall performance.

Designed by computer simulation and aided with the adoption of injection moulding technique, this revolutionized handle style allows the shaft to move more freely, which can not only make swings smoother but also improve overall handling experience.

The integrated force of the shaft and FREE CORE creates a sturdy handling and phenomenal elasticity.
