The new Mizuno ST-G 220 driver adds unparalleled adjustability


By: September 14, 2021


I believe personalization is a must-have and not just a nice gesture or a luxury. We should master how personalization efforts can be used to enhance relationships with consumers, produce customer loyalty and positively impact the bottom line.

This is why I am not surprised that Mizuno is doing (also) great efforts to achieve unparalleled adjustability.

Mizuno ST-G 220 driver – details

In the new Mizuno ST-G 220 driver what really aroused my attention were the high level of adjustability in addition to the super-precise fitting. But how?

The Mizuno ST-G 220 driver has shorter lateral weight tracks allowing a new center/back weight port.  The combination of three tracks and two moveable weights mean the ST-G can be transformed from ultra-low spinning bomber to a highly playable mid-spinning option, with fade or draw bias in both. 

The evolution to the Mizuno ST-G 220 driver’s weight locations offers a rare combination of both backspin and fade/draw adjustability options.

Traditionally, adjustable drivers have been more effective at just one of those tasks. In every setting the Mizuno ST-G 220 driver delivers impressive performance from off-center strikes, with consistent feedback across the varying weight positions.

Like the ST-Z and ST-X, the ST-G 220 driver also features Mizuno’s latest SAT2041 Beta Ti face.

SAT2041 stands for

  • Super / 
  • Alloy / 
  • Titanium / 
  • 20% Vanadium / 
  • 4% Aluminum / 
  • 1% Tin.

It offers 17% more tensile strength and 8% more flexibility than traditional 6-4Ti.

Additional features and benefits:
  • New Multi-thickness CORTECH Face: Refined to maximize the return from Mizuno‘s Beta Ti face. Ball speeds most noticeably improved low on the clubface.
  • New dual weight center slot:  Allows 2 central back weights for deeper CG capability – higher stability, launch and spin.
  • Greater draw / fade bias:  Increased separation between lateral weight tracks.
  • Quick Switch Adjustability: 4 degrees of loft adjustability (7-11 degrees) to fine-tune look and trajectory.
  • Optimized Wave Sole: Delivers an additional contribution to ball speed from low on the clubface.

The new Mizuno ST-G 220 driver will be available at retail from October. Mizuno will sell it for $499.95. Test it at a Mizuno Swing DNA Fitter.

My concerns

  1. It seems like Mizuno wants to offer a driver that can be adjust to various levels of game. Can it work out?
  2. Due to the amount of adjustability in this driver, how can a golfer alone adjust his new Mizuno ST-G 220 driver to his game?
