Callaway Men's XR Pro Driver Higher Ball Speed From RMOTO Face Technology This is the power of RMOTO Technology - it removes weight in the face to increase ball speed and create more efficient energy transfer across the face Low Spin From Forged Composite Crown XR Pro has a 53% lower Center of Gravity and 300 rpm lower spin than X2 Hot Pro; Those are stunning numbers and we've done it in part by designing a Forged Composite crown that takes weight from the crown Maximum Speed In An Aerodynamic Head Shape The Forged Composite crown leads to an enhanced aerodynamic head design that maximizes speed for longer distance OptiFit Adjustability Choose from 8 different loft and lie configurations to find the perfect launch for your ball flight; When you get the right launch conditions, you get more distance That's why you get more ball speed at every impact location, even mishits, that allows us to move the Center of Gravity very low to maximize distance
