Tensei CK Blue Graphite Wood Shaft The new TENSEI CK Series features a multi-material design that optimizes classic, tour-proven MCA GOLF bend profiles in much the same manner as racecar designs use exotic materials to enhance performance and efficiency. This innovative brand debuts in January 2016, with the TENSEI CK Blue Series that includes more materials than any other shaft we’ve ever made to date, making it the most playable of our smooth profiles. The new shaft brand is inspired by the Japanese word “Tensei” – which means “transformation” in English. While a typical shaft series includes three-to-six materials, the TENSEI CK Series combines 11 different prepreg materials, including our Low Resin Content (L.R.C.) Prepreg, ultra-thin prepreg and for the first time a Carbon Fiber/DuPont™ Kevlar weave featuring Mitsubishi Chemical carbon fiber – refining MCA GOLF’s tour-proven, classic smooth bend profile, taking it to an entirely new level. Carbon Fiber/DuPont Kevlar A Carbon Fiber/DuPont Kevlar woven material; featuring Mitsubishi Chemical carbon fiber has been strategically placed under the hands to increase the strength and stability in the butt-section of the shaft in addition to providing superior feel and feedback throughout the swing Ultra Light Weight Materials Our expertise in creating thousands of versions of carbon fiber and resin combinations gives us the ability to create unique high-performance materials designed to deliver exactly what our engineers require to make our ultra-lightweight, high-performance shafts Low Resin Content Prepreg Our Low Resin Content Prepreg, with up to 15% more carbon fiber and much less resin (20% vs. 33%) for more traditional prepreg allows us to create a higher density of carbon fibers without adding additional weight. Result: Added strength with enhanced feel. We've used Low Resin Content Prepreg in our shafts since 2011.
