The new Srixon ZX7 Mk II Driver features Rebound Frame technology. Whereas traditional drivers use a flexible face that compresses and decompresses at impact to propel the ball forward, Rebound Frame adds a second layer of flexibility. Together, the face and frame work like dual springs, transferring even more energy from the club head to the golf ball. By refocusing energy that's ordinarily lost, Rebound Frame is faster on every strike, especially center-face impacts. In fact, Srixon claims that even the most flexible driver face cannot transfer as much energy as Rebound Frame's dual Flex Zones. Center face ball speed is undoubtedly integral to a driver's performance, but mis-hits happen, even for the world's best. Thus, Srixon engineered the Mk II with a variable-thickness face. Comprised of a series of ridges from heel to toe, this unique design delivers phenomenal ball speed across the face by improving how energy reflects into the ball on off-center shots. The compact, confidence-inspiring ZX7 is equipped with two swappable heel and toe weights, as well as an adjustable hosel, allowing players to select the perfect launch conditions needed for maximum workability and complex shot-making.
