Callaway has used Artificial Intelligence to engineer a NEW formula for speed. It’s built on a simple equation: max ball speed (with the new Jailbreak A.I Speed Frame) + maximum forgiveness (with high MOI and adjustable weighting) = the ultimate max driver. Epic MAX creates exceptionally high forgiveness, starting with a lighter, stronger Triaxial Carbon material that saves over 19 grams of weight vs. titanium. Stock shaft: Project X HZRDUS Smoke IM10. Stock grip: Golf Pride Tour Velvet Align black.
