Renowned for its expertise in irons, Mizuno is upping its big stick game big time with its new ST190 drivers and metal woods.
After clearing the USGA conforming list, the ST190s made an immediate first appearance at the British Masters with many players putting in to play on tour since, including Luke Donald and Keith Mitchell to date.
Mizuno has quietly been a pioneer of metal woods for the entire golf industry. From the Ti100 (golf’s first mass-production titanium driver), the Masters winning T-ZOID, MP-001 with composite crown, and the MP-600 with sliding weights – Mizuno has introduced many metal wood technologies widely adopted by the industry.
Now with its early success on tour, the Mizuno ST190 appears set to propel Mizuno into the metal wood spotlight. In addition to being seen in play on tour so soon after its introduction, the ST190 driver was played to win November’s PGA Play-Offs at Antalya in Turkey and worked its way into the bag of Luke Donald. Donald’s driver choices have long been a barometer for the legitimacy of Mizuno’s launches – the JPX850 being Mizuno’s last to enjoy Donald’s prolonged use.
ST190 AND 190G DRIVERS
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 percent 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-center 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.
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-center strikes. The ST190G is engineered for low spin and offers intuitive FAST TRACK adjustability thanks to twin 7g weights on external tracks that can reduce spin by an additional 200 rpm, allowing players to achieve heavy fade or draw biases by placing the weights in one track.
The ST190 driver will be available in men’s 9.5 degree and 10.5 degree models, both adjustable by 2 degrees either way, in right hand and left hand (9.5 degree only). The ST190G driver will be available in men’s 9 degree, adjustable by 2 degree either way, in right hand only. 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.
ST190 FAIRWAY WOODS
The powerful ST190 fairway woods are also speed-engineered and feature a carbon composite crown and amplified Wave soleplate, this time allied to a deeper, high-energy HT1770 Maraging steel face. This deeper clubface flexes more like a driver, helping to maximize ball speed, while the ultra-lightweight carbon composite crown allows 4g of weight to be moved low within the clubhead, combining with the deeper clubface to deliver an efficient, low-spin ball flight.
The Amplified Wave Soleplate’s larger first wave creates a balance between stability and sweet spot height to provide effective off-center forgiveness without excess backspin. Similar Harmonic Impact Technology to that found in the drivers generates a powerful, solid impact sound, fine-tuned through the study of vibration and soundwaves.
The ST190 fairway woods will be available in fixed-hosel 3- and 5-woods along with an adjustable Tour Spoon (TS) 3-wood model that offers a stronger ball flight and in which lofts can be adjusted from 13 to 17 degrees. Again, early tour testing with a PGA Tour player has highlighted an effective relationship between ball speed and spin rates, with gains in the former accompanying reductions in the latter. The ST190 fairway woods will be available in a men’s 15 degree 3-wood (right and left hand), a men’s 18 degree 5-wood (right hand only) and a men’s adjustable 3-wood TS (13 to 17 degree, right hand only). A range of shafts without upcharge will be available, with new options for 2019 including Atmos Blue 6R, Atmos Red 6S, Atmos Red 6R and Atmos Black TS 7S.
