Specifically engineered to reduce spin, the Srixon ZXi LS Driver�perfectly suits faster swing speed players seeking maximum distance with a lower ball and extra rollout. Two sole weights can be interchanged to dial in the preferred launch, spin, speed, and stability characteristics. 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 HZRDUS Gen 5 Black and Golf Pride's Tour Velvet 360, respectively.� Srixon ZXi LS Driver Features: Mid launch, low spin, straight/slight fade flight 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 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 Two weights in the sole can be adjusted to create optimal spin, launch, and forgiveness properties Adjustable hosel allows you to fine-tune loft, lie, and face angle (loft can be adjusted up to +/- 1.5�) Stock Shaft: Project X HZRDUS Gen 5 Black 60/70 Stock Grip: Golf Pride Tour Velvet 360 Headcover and Wrench Included Authorized Srixon Retai
