This driver shaft utilizes a highly elastic, high-strength sheet, which contributes to its increased speed. While offering a similar sensation of speed to the "HR," a high-speed driver shaft in the Fire Express series, it has successfully improved the sweet spot hit rate. This is the first time "TORAYCA® T1100G" and "six-axis woven fabric sheet" have been adopted for an FW shaft in the Fire Express series, resulting in a lighter weight while enhancing overall rigidity.
Furthermore, it incorporates a feature called "power tip structure." By equipping the tip with a tungsten powder sheet, it controls flex while suppressing toe-down and head rotation, leading to an improved sweet spot hit rate, reduced loss of power on impact, and easier control of the launch angle.
To cater to the trend of lighter driver shafts, a 40g range lineup is also available. The appearance features a clear finish at the grip end, silver in the middle, and a black clear finish at the tip, with the visible six-axis woven fabric sheet at the grip end and tip creating a distinctive presence. The matte finish also adds a fresh and premium feel.
