Mizuno ST-G 220 Driver

Three Tracks / Two Moveable Weights

Mizuno ST-G 220 Driver

Gravity-Adjustable Design

A player’s deeper profile with the ball speed of Mizuno's Forged BETA Ti SAT2041 clubface - and unmatched levels of adjustability for precise fitting. The ST-G now has shorter lateral weight tracks - allowing a new centre/back weight port. The combination of three tracks and two moveable weights enable the ST-G to morph from ultra-low spinning bomber to a highly playable mid-spinning option – with fade or draw bias in both.
“Having that little bit of extra adjustability is especially useful out on tour - where we can fine-tune a player's flight. Or make an adjustment for a particular tournament when the player doesn't want the feel of a completely new driver.”

Expanded Adjustability

The evolution of the ST-G’s weight locations offers a rare combination of both backspin and fade/draw adjustability. Traditionally adjustable drivers have been more effective at just one of those tasks. The Mizuno ST-G also impresses in how un-adjustable it feels once set up. In every setting the ST-G delivers impressive performance from off-centre strikes – with impressively consistent feedback across its varying weight positions.

New FAST TRACK for 2022

1 2 2 3
New FAST TRACK for 2022
A new 2-weight rear track for deeper CG capability – higher MOI, launch, and spin
A true front/back neutral, which is the factory setting
More separation between toe and heel tracks for more left/right bias or correction
“The ST-G has so much more effective movement of weight along both the X and the Z axis. We can set it to be very low spin, a more playable mid spin, heavily fade or draw biased and just about anything in between.”

Featuring 2nd generation SAT2041 Beta Ti Face

Mizuno's new Forged SAT2041 Beta Ti face and complex carbon construction to deliver both potent ball speeds and a dense, satisfying sensation at impact.
SAT2041 Beta Ti Face
Supper Alloy Titanium

With 17% more tensile strength and 8% more flexibility than traditional 6-4Ti, SAT2041 has a fine grain structure inherently resistant to fatigue.

A Nippon steel product developed over five years as a lightweight, high strength material for the automotive industry and used for complex cycle parts – requiring intricate design and ability to withstand strong forces. 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.
