Even with a powerful swing, the flex remains small, delivering a sharp return feel.\u003c\/p\u003e\u003cp\u003eNumerous aspects were emphasized during the product development process.\u003c\/p\u003e\u003cp\u003eFirstly, the composite molding of aerospace-grade high-strength carbon fiber \"MR70\" and boron fiber has increased the repulsion feel compared to previous models.\u003c\/p\u003e\u003cp\u003eThis allows players to maintain core strength even with powerful swings, increasing distance without sacrificing control.\u003c\/p\u003e\u003cp\u003eAdditionally, by reinforcing the tip section of the shaft, impact efficiency was enhanced, improving ball speed. This reinforced tip section enables a smooth stiffness distribution that allows players to achieve their intended trajectory, supporting both distance and direction.\u003c\/p\u003e\u003cp\u003eFurthermore, while maintaining overall smooth flex, materials were used appropriately to reinforce only the necessary parts.\u003c\/p\u003e\u003cp\u003eThis enhances the shaft's operability and stability, helping players achieve their best shots.\u003c\/p\u003e\u003cp\u003eThe Diamana BF series is a next-generation golf shaft that combines innovative design and high-quality materials to sensitively meet the needs of players.\u003c\/p\u003e\u003cp\u003eIt will be an optimal choice for golfers seeking a balance of operability, distance, and direction.\u003c\/p\u003e\u003cp\u003e\u003cspecs\u003e\u003c\/specs\u003e\u003c\/p\u003e\u003cp\u003eBF50:\u003c\/p\u003e\u003cp\u003e- Flex:\u003c\/p\u003e\u003cp\u003e-
