Mizuno has unveiled its next-generation ST-G 220 driver, which features new adjustability for more precise fitting.

At the core of the new 2021 ST-G 220 driver from Mizuno is shorter lateral weight tracks, which allow for a new center/back weight port.

2021 Mizuno ST-G 220 driver: The details

The combination of three tracks and two moveable weights is designed to allow players to alter the ST-G from ultra-low spinning to a highly playable mid-spinning option, with fade or draw bias in both, depending on preference. 

The evolution to the ST-G 220’s weight locations offers golfers a rare combination of both backspin and fade/draw adjustability options. Traditionally, adjustable drivers have been more effective at just one of those tasks.

The new ST-G 220 is also designed to deliver performance from off-center strikes across each varying weight position.

Speaking on the new driver and its adjustability features, Chris Voshall, golf club engineer at the company, said

“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.

“The ST-G 220 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.”

The new addition from Mizuno also contains a modern player’s profile, with a deeper face, and shorter back to front look, while still using the full capacity 460cc head size.

A new multi-thickness Cortech Face has been constructed to help allow for the maximum return from Mizuno’s SAT2041 Beta Ti face.

Per Mizuno, SAT2041 stands for Super/Alloy/Titanium/20% Vanadium/4% Aluminum/1% Tin and it offers 17 percent more tensile strength and 8 percent more flexibility than traditional 6-4Ti.

In addition, an optimized Wave Sole is designed to deliver an additional contribution to ball speed from low on the clubface, while the new dual weight center slot allows two central back weights for deeper CG capability in a bid to provide higher stability, launch, and spin.

The driver features four degrees of loft adjustability (7-11 degrees). It will be available at retail on October 14th at a price of $499.95.
