Mizuno ST-G Driver
The Mizuno ST-G Driver encases a stainless-steel weight with elastomeric TPU by creating an additional energy source from the stress on the clubface whilst simultaneously reducing spin rates. Two weights can be pushed to more extreme positions for settings that give lower spin rates. The modern pear shape of the 440cc profile sits perfectly square in a neutral setting. The ST-G also has new Beta Rich Ti LFS, meaning the face material is lighter and faster. This material measures 9% higher in tensile strength for a complex multi-thickness face geometry. Compared to SAT2041, tour testing demonstrated 1.5 mph faster average ball speed. You can also expect a greater level of shot shape adjustability as a result of an extension of lightweight carbon into the toe. The CORTECH Chamber alongside internal tuning ribs allow a more solid feel at impact. Enjoy a quick switch hosel that has 4 degrees of adjustability.
