The ideal shaft, possessing both the lightness of plastic and the high rigidity of metal, has been born. Achieving Lightweight and Unprecedented Strength By utilizing reinforced plastic resin blended with lightweight, high-strength carbon fiber, we have achieved both light weight and high durability. By coating the high-density interwoven carbon fibers with resin, we have achieved rigidity equivalent to that of lightweight metals such as duralumin. Item... Shaft Type... Carbon Shaft Standard...
