A more rounded, deeper profile with weight located closer to the hosel – means slightly higher spinning and draw biased for the majority, but more workable for many elite players (especially in lower lofts). Natural drawers of the ball may find more ball speed from the ST-X. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.
CORTECH CHAMBER
The missing piece: Mizuno’s CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.
Forged SAT 2041 Beta Ti Face
More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.
Unified Sole Composite
Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.
Workable / Draw bias
Weight located closer to the shaft axis can both encourage a more workable or draw biased outcome, dependent on the player.
Deeper Profile
A more rounded look that sits a little taller. Aligns square in the neutral setting.
Quick Switch Hosel
4 degrees of adjustability.
“The new ST-X 230 is a complex character. Although in the higher loft option it’s a higher flying draw-biased option, the 9.5 for many of our tour players was more workable and faster from the face. You really need to hit both models before making any judgements on which is likely to work best for you." CHRIS VOSHALL / MIZUNO GOLF
