GR501 DR and GR601 DR are heavy-weight shafts that generate overwhelming initial ball speed through the fusion of \"weight\" and \"repulsive force.\"\u003c\/p\u003e\u003cp\u003eTheir design concept is \"ultra-fast rebound.\" The double counter design, which optimally distributes weight to the butt and tip sections, and the unique long straight structure, which places the center of gravity and kick point in the same position, accelerate the snapback of the entire shaft.\u003c\/p\u003e\u003cp\u003eThe tip section features a multi-layered arrangement of ultra-high elasticity material, significantly improving the rebound performance at impact. Furthermore, the semi-flat flex design enhances stability during the swing and improves the hitting rate for athlete-oriented golfers.\u003c\/p\u003e\u003cp\u003eFrom driver to wedge, the oscillation frequency is unified with a gentle flow design. This allows for a consistent tempo across all clubs, stabilizing swing rhythm and improving shot accuracy throughout the course.\u003c\/p\u003e\u003cp\u003eThe GR501 is for golfers with mid-range head speeds, while the GR601 is for hard hitters, allowing you to choose according to your playstyle.
