Material Stiffness Integration, MSI, is the main design concept by which Graphite Design develops golf shafts. Composite materials consist of two main components, graphite fiber and resin. The stiffness of each fiber has an impact on how much vibration is transmitted up the shaft affecting the feel of the shaft. The resin acts more like a sponge absorbing the vibrations, creating exquisite feel.
By using proprietary design formulas and a combination of different materials that vary in stiffness and fiber volume, Graphite Design is able to produce shafts that have a better “Feel” than other competitors and deliver Pure DISTANCE and Perfect ACCURACY.
