Mizuno ST-X 230 Driver

Mizuno ST-X 230 Driver

More Workable, Mild Draw Bias

The Mizuno St-X 230 Driver features a draw-biased carbon composite design aided by a heel side sole weight. Built upon the 2nd generation of Mizuno’s Forged SAT2041 Beta Ti face – for potent ball speeds and consistent performance over time.

CORTECH Chamber – The missing piece

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. 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.

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.

Unified Sole Composite

Carbon sole plate now a single piece to allow the forward weight press of Mizuno’s CORTECH Chamber.

X-Axis Design for Draw Bias

Expanded toe located carbon composite window, with heel located sole weight combine to produce a reliable draw bias.

More Compact Profile

Slightly deeper back portion and more upright visual lie angle.

Deeper Profile

A more rounded look that sits a little taller and aligns square in the neutral setting.

Quick Switch Adapter

4 degrees of loft adjustability to fine-tune look and trajectory
