Introducing the FUBUKI K-Series, the newest addition to the FUBUKI Series of premium golf shafts. The K-Series profile utilizes the same Modulus Differential Technology (M.D.T.) found in the FUBUKI Tour and FUBUKI (alpha) profiles in addition to Mitsubishi Rayon’s latest innovation; the Power “Ninja” Core. This new technology allows Mitsubishi Rayon to incorporate a thin layer of metal in the butt section of the shaft to increase stability and maximize the power stored during the loading of a shaft, unleashing maximum potential energy to the ball at impact. Designed utilizing Mitsubishi Rayon’s propriety swing analysis software, the FUBUKI K-Series bend profile delivers smooth acceleration, increased butt section stability, and a slightly lower launch and spin than the FUBUKI profile.
