The Light Weight but Rigid Shaft
realized by utilizing the latest technology
for maximum driving distance
The Fire Express K2 is the high performance shaft light in weight but with a high rigidity. A combination of high modulus graphite sheets and the high tensile graphite “TORAYCA® T1100G” is applied to this shaft. While the high modulus graphite has a large proportion of layered section to provide a positive response, the “NANOALLOY® Technology” is applied to ideal positions to provide a superb combination of comfortable flex and solid feel.
The light weight shaft effectively enhances swing speed while the rigid design improves the smash factor. Through our rigorous human trials, we compared different rigidity distribution to create the K2 shaft which accelerates the swing speed while maintaining the swing tempo thereby improving the driving distance performance.
This shaft can utilized with drivers in various lengths. The K2 shaft used to create an extra length driver (over 46 inches) gives players an advantage of enhanced swing speed. The rigid tip effectively controls the face turn and provides the smash factor. The shaft can be trimmed for a normal length driver to counter a pull trajectory to make sure players stay on the fairway.
