The ZXi MAX is the highest MOI and most forgiving driver in Srixon's ZXi lineup thanks to an extremely low and deep rear stability weight. The driver's slight draw bias helps correct the unwanted slice to produce longer, straighter tee shots. All three ZXi Driver models see a distance boost thanks to a new i-FLEX face. Completely redesigned from the ground up, i-FLEX increases structural strength, allowing the center of the face to be thinner and more flexible than the previous offerings. As a result, a greater rebound or trampoline effect occurs at impact, increasing ball speed. Additionally, i-FLEX's advanced variable thickness design more efficiently transfers energy across the face to preserve ball speed on mishits. The stock shaft and grip are Project X's Denali Red and Golf Pride's Tour Velvet 360, respectively.� Srixon ZXi MAX Driver Features: High launch, mid spin, straight/slight draw bias Added strength of the i-FLEX face structure allows the center of the face to be thinner than the previous generation, resulting in increased ball speed Rear stability weight pushes the center of gravity low and deep for exceptional MOI, stability, and forgiveness Redesigned i-FLEX face thickness pattern transfers energy more efficiently at impact Unique Rebound Frame utilizes two flex zones instead of one to maximize flex across the face for increased power, ball speed, and distance on every strike Complex latticework creates the structural integrity to support an ultralight, remarkably thin Star Frame titanium crown, allowing discretionary mass to be redistributed throughout the head for optimal stability, launch, and spin Laser Face Milling stabilizes spin, especially in wet conditions Adjustable hosel allows you to fine-tune loft, lie, and face angle (loft can be adjusted up to +/- 1.5�) Stock Shaft: Project X Denali Red 50 Stock Grip: Golf Pride Tour Velvet 360 Headcover and Wrench Included Authorized Srixon Retailer Product Specs Loft Lie Length Volume Swing Weight
