Mizuno ST-X Driver Clearance
The Mizuno ST-X Driver is a draw-biased carbon composite construction 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. Slower swing speeds will benefit from the J-Spec – incorporating an incredibly lightweight 39g MFusion graphite shaft.
- SUPER / ALLOY / TITANIUM – 20% Vanadium / 4% Aluminium / 1% Sn
- 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.
- NEW MULTI-THICKNESS CORTECH FACE STRUCTURE – Refined to maximize the return from Mizuno’s Beta Ti face. Ball speeds most noticeably improved low on the clubface.
- ‘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.
- X-AXIS DESIGN FOR DRAW BIAS – Expanded toe located carbon composite window, with heel located sole weight combine to produce a reliable draw bias.
- OPTIMIZED WAVE SOLE PLATE – Delivers an additional contribution to ball speed – especially low from the clubface.
- MORE COMPACT PROFILE – Slightly deeper back portion and more upright visual lie angle.
- QUICK SWITCH ADJUSTABILITY – 4 degrees of loft adjustability to fine-tune look and trajectory.
- “In testing, a lot of our tour players preferred the ST-X over the ST-Z for its deeper shape and slightly smaller profile. I’d recommend starting with an open mind and dropping the ST-X alongside the ST-Z in the address position. For a draw bias driver, it’s not going to be what most players expect.” – Chris Voshall
