Tour AD HD - Hyper Drive

Graphite Design introduces the latest in the Tour AD premium line of golf shafts, the Graphite Design Tour AD HD - Hyper Drive.  Designed and manufactured at the Graphite Design Japan factory headquarters, the new Tour AD HD wood shafts are white with light blue accents and finished with a matte clear coat.

The Tour AD HD, like the other high performance Tour AD wood shafts, utilises premium aerospace quality carbon fibre materials and are available in 40g, 50g, 60g, 70g and 80g.

The Tour AD HD shaft profile is firm in the butt section, firm in the centre section and has a firm tip to promote a mid launch angle and low/mid ball spin rates.


The Tour AD HD shafts utilise the exclusive Graphite Design FTT - Fast Taper Technology, the modern TORAYCA® M40X carbon fibre material in the mid to tip section of the shaft and the ultra high modulus TORAYCA® T1100G carbon fibre material in the tip section of the shaft.  This creates unrivalled shaft stability and precise ball control without the loss of the exceptional feel that Graphite Design shafts are so well known for.


Features & Technology

  • TORAYCA ® MX40 carbon fibber pre preg.
  • TORAYCA ® T1100G carbon fibre pre preg with NANOALLOY ® technology for increased stability in the mid to tip region for unsurpassed feel.
  • FTT - Fast Taper Technology.
  • 50 tonne ultra premium, high modulus, aerospace quality carbon fibre material.
  • Graphite Design proprietary Material Stiffness Integration (MSI).
  • DI TECHNOLOGY - Consisting of the advanced, 1st generation of Toray Composites NANOALLOY Material Technology for increased stability in the mid to tip region providing unsurpassed feel.


TORAYCA® M40X pre preg is the latest in cutting edge carbon fibre materials from Toray Industries, Inc.  

Prior to TORAYCA® M40X, carbon fibre pre preg materials were either high in tensile modulus or high in tensile strength, but not high in both.  The new TORAYCA® M40X pre preg offers a large improvement in tensile strength with an increase of 30% over conventional carbon fibre materials.


The new and revolutionary TORAYCA® M40X pre preg now allows engineers to develop high performance Graphite Design golf shafts with an even higher degree of shaft zonal tuning without adding weight to the design, resulting in a higher degree of shaft stability and an increased feeling of total ball control over conventional golf shafts.


TORAYCA ® pre preg using T1100G carbon fibre with NANOALLOY ® technology is the latest in cutting edge carbon fibre materials from Toray Industries, Inc.

Unlike conventional pre preg materials, this revolutionary new material is comprised of both high modulus and high tensile strength fibres.  The resin system of TORAYCA ®T1100G is also based on NANOALLOY® Technology for added strength and vibration dampening.


The new TORAYCA ® T1100G advanced material technology allows Graphite Design engineers to fine tune specific zones of the shaft stiffness for added stability without a gain in structure weight.  TORAYCA ® T1100G is the next generation of high performance

Tour AD graphite golf shafts that provide superior accuracy and distance with every shot.  This technology may be found in the MAD, Tour AD M9003, Tour AD GP, Tour AD TP and Tour AD IZ series of wood shafts.

FTT – Fast Taper Technology

Fast Taper Technology or FTT technology is based on the tooling called the mandrel that the shaft is moulded around.   The Fast Taper Technology incorporates a faster taper rate in a specific section of the mandrel used to create a unique shaft profile.  


The Fast Taper Technology of the Tour AD VR shaft starts in the handle or grip section and extends to the lower mid section of the shaft.  The Fast Taper Technology of the Tour AD TP shafts starts in the lower mid section and extends down to the tip of the shaft.   The end result of using the Fast Taper Technology is the overall feeling of greater club head control at impact and an increase in club head speed through the swing.

MSI Technology

Material Stiffness Integration - MSI, is the main design concept by which Graphite Design develops golf shafts.  Composite materials consist of two main components, graphite fibre and resin.  The stiffness of each fibre 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 fibre volume, Graphite Design is able to produce shafts that have a better feel than other competitors.  Graphite Design deliver pure distance and perfect accuracy.
