The Carbon MTX adds another high-performance shaft to the Carbon family. Featuring additional TeXtreme® reinforcement, the Carbon MTX is engineered for grinders. TeXtreme® is an ultra-light and strong carbon fiber technology that weighs 20% less than typical carbon fiber reinforcements. It reduces weight without sacrificing strength or stiffness and helps prevent micro cracks in your shaft. Flex1 for stiffness you can trust.
