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 CK Blue line is mid-launch and mid-spin.
