Mizuno ST-Z 230 Driver
A balanced toe/heel carbon composite construction with deep central back weight – for a spin efficient, straight-line ball flight. Built upon the 2nd generation of Mizuno’s Forged SAT2041 Beta Ti face – for potent ball speeds and consistent performance over time.
Technical details
- Highly resilient Forged SAT2041 Beta-Ti Face: As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4 Ti.
- Quick Switch Adaptor: 4 degrees of loft adjustability to fine-tune look and trajectory
- Z-Axis design for straight line flight: Balanced use of carbon composite on the sole and deep central sole weight are biased towards a straight-line flight and low spin efficiency. Wide, low footprint: With neutral visual lie angle ‘Dense’ or solid feedback: The majority of Mizuno’s tour players expressed a preference for more dense feedback through impact. Mizuno’s engineers spent a year finessing the sound to a more muted, powerful tone.
- CORTECH Chamber:Â The Missing Piece: Â Mizuno’s CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU, taking stress from the club face and creating an additional energy source. Â At the same time, locating weight closer to the club face to reduce spin rates, while contributing to a more solid, powerful sensation at impact.
- Unified Sole Composite: A carbon sole plate that is now a single piece to allow weight to be pushed to the extremes for overall stability.
