FULL DESCRIPTION

THE LEGENDARY PROFORCE FEATURING BOOSTED PERFORMANCE WITH M40X!

Our engineers were able to create a lighter, high performance Proforce model with increased strength. Incorporating M40X material into the new shaft design provides significantly improved lateral stability to the shaft during the golf swing. Ultimately delivering increased energy to the golf ball at impact and more consistent release path.

 

REVOLUTIONARY MATERIAL  |  INNOVATIVE DESIGN 

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/stiff feel.   M40X eliminates this negative aspect through the use of proprietary nano technology and nanoalloy used in the prepreg matrix resin.  The novel combination significantly improves shaft feel and performance.
