The ST190 is designed for mid to low spin with maximum stability, and features a single, factory-fixed 6g backweight that adds 300gcm2 MOI for added stability on off-centre strikes.
The ST190 driver is available in men’s 9.5˚ and 10.5˚ models, both adjustable by 2˚ either way, in left and right hand.
A range of shafts without upcharge will be available, with new options for 2019 including Atmos Blue 5S, Atmos Red 5R, Atmos Red 5R2, Atmos Red 6R and Atmos Black TS 6S.
The ST190 drivers offer Mizuno’s lowest spin rates and incorporate every known factor in the quest to enhance ball speed and driving distance. Mizuno’s ultra-fast Forged SP700 Ti face now boasts a lighter CORTECH structure to deliver consistently higher ball speeds, with a large carbon composite crown plus the Amplified Wave soleplate, introduced in last year’s ST180 drivers, helping to convert each additional mph into extra yards.
The Forged SP700 Ti face is over 10% stronger than 6-4 Titanium with a fine grain structure that allows a more complex geometry in the CORTECH face, where re-engineered ribs and a Quick Switch internal structure promise even higher performance. The ultralight 12g carbon composite crown means 7g of weight can be optimally redistributed to further boost ball speeds and reduce spin rates. The Amplified Wave Sole features a heavily amplified first wave configuration which expands the ST190’s COR area for improved balls speeds across the clubface, with reduced off-centre performance drop-off. Harmonic Impact Technology is the result of a careful study of vibration and soundwaves, which identified the need for internal ribs to create a more solid, powerful impact sound. The whole package combines to squeeze every last ounce of ball speed from the entire clubface in both the ST190 and ST190G drivers.
Mizuno’s ST190G driver (scheduled for Feb 2019 delivery) added to its growing reputation on tour with a win at the PGA Championship in Turkey, Antalya . In the hands of Englishman David Dixon who qualifies for the British Masters and BMW PGA Championship at Wentworth. The ST190 is already Mizuno’s most successful tour driver for many years – going straight into play on both the US PGA and European Tour, just days after appearing on the USGA conforming list. Mizuno testing has seen increased ball speeds and reduced spin rates compared to prior models.
