The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Nano Fortify is composed by numerous tube-shaped carbon fiber.This technology can optimize high resilience. With bending strength to generate high repulsion, which enhance attacking power on every single hit.
