ProForce M40X Wood Shafts – The Legendary ProForce is upgraded with performance boosting M40X High Tensile Modulus material. UST Mamiya engineers have created a higher performing ProForce with increased Strength. Incorporating M40X into the new shaft design provides significantly improved lateral stability to the shaft during the swing delivering increased energy to the golf ball at impact and a more consistent release path, swing after swing. M40X represents a major advance in carbon fiber technology. TORAY Industries pushed both fiber strength and tensile modulus to the extreme and applied technology to improve fiber orientation by closely controlling the graphite crystal structure in a Nano order. The result is a revolutionary material that offers a 30% improvement in tensile strength over conventional carbon fiber. Historically, high tensile modulus materials used in golf shaft design result in a “boardy feel” M40X eliminates this negative aspect through the use of proprietary nanotechnology and nanoalloy used in the prepreg matrix resin. This combination improves feel and performance. R,S,X
