Welcome to Select Items Norisuke. We are Japanese seller. We ship authentic items from Japan. Please enjoy shopping with peace of mind! You will find popular and useful products in Japan! The "ST-MAX 230" series is equipped with the next-generation "Core Tech Chamber" and pursues high initial velocity, low spin, and stability. Improved the current "Core Tech Chamber" which had a weakness in performance at the heel point of impact. By extending the ``Core Tech Chamber'' to the inside of the click switch and moving it closer to the center of the club face, we have expanded the high initial velocity area. Adopts forged Ti-LFS, which is lighter, faster, and stronger than the forged β titanium currently used in the ST 230 series. In addition to increasing ball speed with the high-strength face, excess weight is added to the rear and lower part due to lightweighting, achieving a design with higher stability and higher initial velocity. The Core Tech face, which was completed using Forged Ti-LFS, is a technology that delivers high repulsion performance that is at the limit of the rules over a wide range. Mizuno's unique face thickness design increases the deflection of the face by making the center thicker and the periphery thinner. ST-MAX 230 has expanded the high initial velocity area by making the toe and heel thinner. Mizuno's proprietary technology, ``Coretech Chamber,'' which further pursues ball initial velocity, is a technology that improves repulsive force by using a stainless steel core that is integrally molded with urethane resin. Due to the collision between the head and the ball, the iron core stainless steel, which is integrally molded with urethane resin, has momentum in the direction of the flight line, improving the ball's initial speed and pursuing distance performance. *Torque wrench for Mizuno golf clubs is not included (sold separately/model number: 5KJLW800)
