This factory replacement sleeve will fit the New Mizuno ST 190 … this sleeve is different that the JP 850, 900
The Mizuno ST190 drivers 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 sole plate to convert each additional mph into yards gained. Twin 7-gram weights on an intuitive Fast Track can adjust spin or influence fade or draw bias.
“The genius of the new Fast Track is that it adds the dimension of launch angle and spin rate. Now the player is truly in control of maximizing all aspects of their ball flight off the tee.”
Available .335 includes screw and washer will fit Driver
