Mizuno ST-G Custom Driver


Mizuno’s player’s driver combines the scope to optimize launch and spin with the ball speed enhancements of Mizuno’s CORTECH Chamber. Two convergent weight tracks allow the ST-G to be anything from a low spin bomber, fade or draw biased or, simply a more stable compact driver.

  • Beta Rich Ti LFS Face: A new lighter, faster face material! Measuring 9% higher in tensile strength (compared to SAT2041) for a complex multi-thickness face geometry. Tour testing demonstrated an average 1.5 mph ball speed increase compared to SAT2041.
  • CORTECH Chamber: THE MISSING PIECE: Mizuno's CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU, taking stress from the club face and creating an additional energy source. At the same time, locating weight closer to the club face to reduce spin rates, while contributing to a more solid, powerful sensation at impact.
  • Max Convergent Fast Track: Mizuno's weight track system that allows for optimizing launch conditions. Two weights can be pushed to more extreme positions for ultra-low spin to mid-low spin settings.
  • Compact 440cc Players Profile: An inviting modern pear shape that sits perfectly square in the neutral setting.
  • Ultra-lightweight Carbon Crown: Ultra lightweight carbon allows weight to be moved low within the clubhead.

An extension of lightweight carbon into the toe section allows an even greater level of shot shape adjustability.


A combination of Mizuno's CORTECH Chamber and internal tuning ribs creates a more solid feel at impact - in the full range of weight settings.


4 degrees of adjustability to fine-tune address and trajectory.

Mizuno ST-G Custom Driver Shafts


Aldila Ascent Red This unique enhancement – created by pairing a strategically-placed section of increased stiffness with a focused area of heavier, tungsten-infused prepreg – preserves the shaft’s lively feel and higher launch angle while maintaining stability and maximum energy transfer at impact.


Aldila Ascent Ultralite models also feature FlyDrive™ Technology – a new application inspired by a similar innovation in high-performance fly fishing rods. A unique, full-length Visco-Elastic Isolation Layer (VEIL) is added to improve overall strength and feel while bolstering the shaft’s resistance to “ovaling,” a common deficiency in thinner-walled designs.

Fujikura Ventus Black a multi-material bias core construction technique that delivers ultimate stability through transition and impact (maximizing clubhead MOI) – increasing velocity and smash factor.


Fujikura Ventus Blue designed to significantly tighten shot dispersion and maximize ball speed especially on off-center shots. Ventus is a Tour-inspired profile and the first to include Fujikura’s all-new VeloCore Technology in an accelerated taper, ultra-stiff tip profile.


Fujikura Ventus Black TR ultra-stiff tip and handle sections work in unison to support players with Tour-like speeds that prefer the feeling of minimal to no flex during the swing.


Fujikura Ventus Blue TR powerful combination of stability and feel, TR Blue maintains an ultra-stiff tip section for superior control at impact.


Fujikura Ventus Red TR softest tip section of the TR lineup is ideal for players seeking a mid-high launch profile with controlled spin and increased stability.


Fujikura Motore X F3 features a reinforced bias core with a torsionally stiffened handle section that promotes faster ball speeds combined with thin layers of full-length bias plies that create a balanced torsional strength for stability.

Graphite Design

Graphite Design Tour AD - DI shaft is designed to provide more power and stability. The Tour AD DI manufactured exclusively at Graphite Design Japan has been integrated with Toray Company's new Nanomaterial technology in the tip section of the shaft. This unique technology allows the player to create an epic IMPACT on ball speed while still providing exceptional feel and control.


Graphite Design Tour AD - XC shaft profile is softer in the butt section, stiff in the center section and has a stiff tip to promote low/mid launch angle and low spin with the ball.
