The UST Mamiya Recoil 440/450 ES Wood Shafts are designed using Recoil Technology which optimizes the spring effect in the multi-layered graphite walls of the golf shaft for more efficient energy transfer to the ball resulting in greater distance and shot dispersion. Features: Ultra-Lightweight wood shafts designed using Recoil Technology to provide greater consistency, distance and trajectory control. Optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball at impact produces increased velocity and greater distance. Ion Plating (IP) creates a stunning and premium finish. Designed for the player looking to increase initial launch and maximize distance. Click here for Trimming Instructions
