This mid-kick shaft is designed to flex softly near the grip, rather than the handle, allowing for a natural lag in the downswing. This helps the shaft to automatically produce a stable and consistent trajectory without rushing the swing. Unlike previous UST Mamiya shafts, this one utilizes a more resilient material. Furthermore, "Torayca M40X" is used in the tip section to achieve high-elasticity repulsion. Additionally, the "S.T.T (Strike Torque Technology)" has been newly developed to reduce torque and is incorporated into this shaft. This makes it particularly compatible with the current mainstream 10K and MAX series heads with large moment of inertia, helping to reduce head wobble. The 5x is a light-stiff shaft, but when combined with a shaft that allows for aggressive swings, it produces a pleasant, high-draw trajectory without the typical hooks or slices, even if you get tense. 【Product Information】 ■Manufacturer: UST Mamiya ■Model Name: ATTAS DAAAS 5X ■Club: Driver Shaft ■Flex: X, 59g, Torque 4.3 ■Kick Point: Mid ■Sleeve: TaylorMade ■Grip: IOMIC 【Specifications】 ◇Length: Approximately 45.25 inches when installed on the head (shaft alone measured 113.7 cm) ※Please forgive any slight errors due to simple measurement.
