The MATRIX Shafts TOPS Series for Driver Wood uses the HD design, which refers to the internal structure of the rod body with 16 diamond-shaped sections to form 16 angles. The HD design uses a new structural strength adjustment of the rod body, and uses high-strength, ultra-heat-resistant, high-elastic UHN, UMN yarn carbon fiber material as the main material to make the shaft BUTT stronger. The internal structure is very stable, can withstand strong forces, and enhance the TIP end of the force fast output; The bevel cross mixing process in HD technology can also increase the inertia of the shaft at the same time, and the center of gravity is better matched to the shaft head, thus achieving a more stable ratio of strength to center of gravity of the shaft.
