Rogue ST MAX is Callaway's highest MOI head with a slight draw bias that's built for all levels of golfers. This is the best combination of distance and forgiveness in a Callaway driver. The groundbreaking new Tungsten Speed Cartridge structure places up to 26 grams low and deep in the driver head. This increases speed on off-center hits and provides more forgiveness through high MOI. Callaway's patented A.I. designed Jailbreak Speed Frame provides stability in the horizontal and torsional direction. They've speed tuned the construction, shaping, and positioning to deliver even more speed across the face. As the industry leader in Artificial Intelligence, Callaway has added launch and spin to ball speed in their optimization formula. This new formula lowers spin on the face, allowing for added forgiveness to the driver. The titanium unibody construction provides stability and lowers the center of gravity, while Callaway's proprietary Triaxial Carbon crown and sole allow engineers to save weight. This weight is precisely redistributed to increase forgiveness with high launch and a slight draw bias. If you would like to customize the shaft, grip or length, please include a request in the order comments / shipping notes section. Standard Callaway warranty applies.
