Launched along with the ST-Z 230, the two drivers replace the 220 drivers series as Mizuno’s leading range.

The new ST-X 230 has been added to the USGA conforming list and is being put through its paces with heavy testing on tour before the driver goes on sale in 2023.

There is also an ST-Z 230 Pltnm driver added to the conforming list in what looks to be a new model to the range.

What Mizuno says about the ST-X 230 driver:

“The USGA has approved and added Mizuno’s 2023 drivers to its conforming list.

“The new ST-Z and ST-X 230 drivers are now eligible to play on tour.

“The ST-Z was being heavily tested at the Mizuno supported British Challenge in St Mellion. Both Mizuno’s OJ Farrell and Marco Penge are believed to have taken the new drivers away after successful testing.”

Mizuno ST-X 230 Driver Specs & Design

Little is being given away by Mizuno when it comes to the design tweaks and changes from the ST-X 220 to the new 230 model.

One key change appears to be the addition of a Cortech Chamber in the sole compared to its predecessor with this element like to be designed to enhance ball speeds across the face.

The Cortech CT ribs in the 220 version were all about delivering a higher speed and the new Chamber seems to have been created with the same intent. It could well replace Mizuno’s wave sole on the base of the club head.

The ST-X 230 will once again have a Titanium face, while this will be the draw bias model with weight positioned towards the heel and the back as it was in the 220.

The 220 driver was high a high-launching draw bias option and this model looks like improving on the consistency and performance with design tweaks.

Mizuno have typically offered this model in 10.5 and 12 degree lofts with four degrees of adjustability (8.5-12.5 and 10-14).

On the USGA Conforming List, Mizuno have also got approval for an additional version of the ST-X 230 with a Pltnm model. We wait to find out the differences between the two designs.

Verdict: Is the Mizuno ST-X 230 driver any good?

It is a wait and see question. From the initial looks, there isn’t a great deal of difference between the 220 and 230 models, but the proof is the testing.

Mizuno’s team have added a Cortech Chamber to this model in search of increasing ball speeds and remaining competitive in the driver space.

It will be interesting to see how much the gains actually are when the wraps come off this driver and to see the improvements made.
