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

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. 

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 introduction of nanotube material can effectively improve the strength, elasticity, and anti-fatigue performance. The lightweightness also ensures a soft feel to the grip.

The combination of thin metal sheet and high-strength carbon fiber which fused into Metallic Carbon Fiber. This ensures a unique and elastic feeling, guaranteeing an unparalleled hitting experience. The introduction of Metallic Carbon Fiber into the frame helps boost the power of smashes and the strength of the frame. The introduction of Metallic Carbon Fiber into the shaft brings highly elastic hitting feel and better force transmission. Elavating the speed of shots and precise directivity.
