Forged SP700 Ti. Carbon Composite Crown. Speed Engineered.
The Mizuno ST190 combines every known factor to deliver ball speed and driving distance – aligned with our lowest ever spin rates. Mizuno's ultra-fast Forged SP700 Ti face is enhanced with a lighter CORTECH structure for consistently higher ball speeds. Combined with a large carbon composite crown and Amplified Wave soleplate to convert each additional mph into yards gained.
ST190 and ST190G DRIVERS
Two drivers sharing the same ball high speeds from our exotic Forged SP700 Forged Ti face and CORTECH structure. Choose
- ST190 for mid to low spin with maximum stability
- ST190G for low spin with maximum adjustability
ST190 / Single 6g back weighting
- Factory fixed backweight adds 300 gcm^2 MOI for stability from off centre strikes.
Forged SP700 Ti face - More than 10% stronger than 6-4 Titanium with a fine grain structure that allows a more complex geometry for our CORTECH face. Internal testing proved higher performance than 6-4 Ti at 90mph, 100mph and 110mph head speeds.
Carbon Composite Crown - A 12-gram carbon composite crown allows 7 grams of weight redistributed across the ST190 for consistently higher ball speeds and reduced spin rate. Our ratio of carbon crown to bonding area increased to 5:1 from 3:1 on Mizuno’s previous carbon crown (MX500).
Amplified Wave Sole - A heavily amplified 1st wave configuration expands the ST190 CORAREA for improved balls speeds across the clubface and reduced drop off from off centre strikes.
Harmonic Impact Technology- The study of vibration and soundwaves identified the need for internal ribs - creating a more solid, powerful impact sound.
Speed Engineered - Performance of our exotic SP700 Forged Ti face moves to new levels with improved internal engineering. The ST190 CORTECH face, re-engineered CT ribs and Quick Switch internal structure combine to squeeze ball speed from the entire clubface.
Kei Tsjui – ST190 Lead Designer - “The ST190 marks a total change in how Mizuno approaches wood design. We now start the development process with our tour players. The tour tested moulds then become our production moulds. In the case of the ST190, this produced a high-speed driver with extremes low spin for the tour, but with the capability of increasing spin for lower swing speed players. We also learned to slightly roll back the level of adjustability to gain performance. Losing the central weight track helps reduce the lower end of spin rates and gave us the design freedom to deliver a 3mph ball speed increase on our previous models.”
Chris Voshall - Mizuno - “One thing that’s increasingly evident is the increasing trend to a lower spin bias on tour - so many players we’ve tested with favour a downward angle of attack. They need their driver to knock the spin down to compensate, which became our 2nd objective with the ST190. No.1 was always ball speed – if we can add 1mph, that’s what we’re going to do.”
Keith Mitchell – PGA Tour Professional - “Driving was my best category last year – I walked into testing to do ‘Cookie’ (Mizuno, PGA Tour Manager Jeff Cook) a favour, give him some numbers and leave. It turned out to be the easiest change I’ve ever made – on the one club I never thought I would switch. The ST190 was faster, straighter and more forgiving than what I was playing. I’ve used it ever since and haven’t considered taking it out.”
