Mizuno’s new ST Series drivers represent the culmination of the Japanese company’s 3-year, rapid-fire driver development project. Preceded by the highly acclaimed ST190 and ST200, Mizuno’s first drivers widely played by its global tour staff, the new ST-Z and ST-X further deploy Mizuno’s new SAT2041 Beta Ti face and complex carbon construction to deliver both potent ball speeds and a dense, satisfying sensation at impact.
SAT2041 stands for Super / Alloy / Titanium / 20% Vanadium / 4% Aluminium / 1% tin and it offers 17% more tensile strength and 8% more flexibility than traditional 6-4Ti.
A Nippon steel product that was developed over five years as a lightweight, high strength material for the automotive industry and used for complex cycle parts requiring intricate design and an ability to withstand strong forces, SAT2041 has a fine grain structure inherently resistant to fatigue. As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4, Alpha Beta Ti.
The ST Series offers a choice of two different head designs in the driver, with characteristics to suit different playing requirements and deliver different ball flights.
ST-Z Driver
The ST-Z driver has been designed to be ultra-stable and to offer low-spin efficiency. It has a balanced toe/heel carbon composite construction with deep central back weight – for a spin efficient, straight-line ball flight. It features the 2nd generation of Mizuno’s Forged SAT2041 Beta Ti face for potent ball speeds and consistent performance over time.
A balanced use of carbon composite on the sole and a deep central sole weight are biased towards a straight-line flight and low spin efficiency. The ST-Z driver has a wide, low footprint, with a neutral visual lie angle and comes with 4 degrees of quick switch adjustability to fine-tune look and trajectory.
ST-X Driver
The ST-X driver features a draw-biased carbon composite construction aided by a heel side sole weight. Like the ST-Z, it’s built upon the 2nd generation of Mizuno’s Forged SAT2041 Beta Ti face to produce potent ball speeds and consistent performance over time.
An expanded toe located carbon composite window, with a heel located sole weight combine to produce a reliable draw bias. The ST-X driver offers a more compact profile, a slightly deeper back portion and more upright visual lie angle and also comes with 4 degrees of quick switch adjustability.
As with the ST-Z, the ST-X offers more dense feedback through impact and a more muted, powerful tone.
Those with mid-lower swing speeds will benefit from the J-Spec, Japan Specification, incorporating an incredibly lightweight 39g MFUSION graphite shaft.
ST-Z Fairway Woods
Offering high levels of stability and low spin efficiency, the ST-Z fairway woods offer a throwback profile, with curves for the purist and performance for the pragmatist.
Mizuno’s 3rd generation MAS1C face is Mizuno’s most powerful to date. The ST-Z fairway woods provide a balanced package of low spin performance and stability, not common in most fairway woods. Both 3 and 5 woods have an adjustable, quick switch, hosel offering 4 degrees of loft and face angle adjustability.
The ultra-lightweight carbon crown lowers the COG for better spin vs MOI performance, while re-engineered WAVE Technology, delivers a compact wave design that lowers the mass
