MIZUNO ST-Z 230 Driver
Item No. 40137672
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.
Straight flight bias: Mass spread evenly to encourage a highly stable, straight ball flight.
Modern Players Profile: Pushed lower to the ground for low / mid spin performance and aligns square to open.
Quick Switch Hosel: 4 degrees of adjustability.
