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

Combining the controllability of “diamond-shape” structure with the stability and smoothness of “sword-shape” structure, AERO-DIAMOND frame minimizes air-resistance and improves handling stability during each game. 

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.

Introducing brand new elastic and durable carbon fiber to further strengthen the frame with better resilience and durability.
