Loading Zone Technology is achieved through variable wall technology in the shaft’s butt and tip sections and a reduced stiffness in the midsection. Golfers can not only feel the technology, but can see it, in the rapid tapered steps from the grip through the midsection of the shaft. Project X’s unique Loading Zone Technology is specifically positioned to maximize shaft load for greater energy transfer and increased ball speeds. Loading Zone Technology is created by thinning out the walls of the mid-section of the shaft, causing it to be more flexible, while reinforcing the butt and tip sections of the shaft to maintain stability and control. This provides a very unique design, profile and feel when compared to other shafts. Available in chrome and blackout finish.
