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. 

Based on the design of multi-layered carbon fiber, the advanced Fiber Reinforced System (FRS) can not only improve the elasticity, but also offer stable controllability with high tension string.
