MIZUNO ST190 DRIVER

ST190 For Mid To Low Spin With Maximum Stability

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 / 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.

• Tour Testing
Early tests with 2 PGA Tour players showed the right combination of spin rate and ball speed was key to increased distance.
