Rogue ST MAX D is built for a high level of draw bias, with high MOI, a more upright lie, reduced face progression, and a stretched profile. All these features promote maximum shot shape correction for players who tend to slice the ball. The groundbreaking new Tungsten Speed Cartridge structure places up to 20 grams low and deep in the driver head. This increases speed on off-center hits and provides more forgiveness through high MOI. Their patented A.I. designed Jailbreak Speed Frame provides stability in the horizontal and torsional direction. Callaway has speed tuned the construction, shaping, and positioning to deliver even more speed across the face. As the industry leader in Artificial Intelligence, Callaway added launch and spin to ball speed in our optimization formula. This new formula lowers spin on the face, allowing us to add forgiveness to the driver. Titanium unibody construction provides stability and lowers center of gravity, while our proprietary Triaxial Carbon crown and sole allow us to save weight. This weight is redistributed to increase forgiveness with high launch and a slight draw bias.
