This includes the flex from the take-back to the top, and the reverse flex from the top to the downswing. This difference in flex amplifies power during the swing, maximizing club head speed. Additionally, the flex point is designed to optimally shift with centrifugal force during the swing, creating a powerful impact.\u003c\/p\u003e\u003cp\u003eWith a generally suppressed rigidity structure, the entire shaft allows for a flexible swing. It not only increases distance by utilizing the \"Whip\" effect but also compensates for deceleration during mishits. Optimal torque significantly improves directional accuracy. Furthermore, with a single weight class and a single flex setting, it achieves the same quality as the top brand \"Fire Express.\"\u003c\/p\u003e\u003cp\u003eIt is suitable for head speeds of 38-45m\/s. It's perfect for players who are not satisfied with the stock shafts of off-the-shelf clubs or those who seek a swing that utilizes shaft flex.
