Fujikura's original 3D motion capture system "enso" and "VTC" that precisely controls torque distribution were adopted, and the first generation "NX" evolved from 2D to 3D design. It is based on such a first-generation model and designed with a smooth EI distribution with little undulation.

On the other hand, the difference in torsional rigidity between the middle part and the hand side is increased to create a shaft that can be turned flexibly. In addition, by increasing the bending rigidity on the tip side, it is possible to push the impact and further increase the ball speed. It is a shaft that has high straightness and achieves a strong trajectory.
