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.

The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension. 

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.

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