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.

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.

ULTRA-THIN FRAME is now 7% thinner than the frame of traditional rackets. This helps to improve the player's swing speed while maintaining the stiffness and torsional resistance of the frame.
