Do you remember Mizuno‘s first drivers the ST190 and ST200?
The new Mizuno ST-Z driver and ST-X driver 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 5 years as a lightweight, high strength material for the automotive industry.
It is used also 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 Mizuno ST Series offers a choice of two different head designs in the driver.
Mizuno ST-Z Driver
The Mizuno 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 a 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.
The Mizuno 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.

Mizuno ST-X Driver
The Mizuno ST-X driver features a draw-biased carbon composite construction aided by a heel side sole weight.
Like the Mizuno ST-Z driver, 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 a 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.
