Callaway Epic Speed Fairway Callaway is looking to lead a fundamental shift in the fairway wood category. In 2021, fast is going to get faster, long is going to get even longer, and straight is going to get a lot straighter. FAST Epic ball speeds start with new Jailbreak A.I. Velocity Blades. Callaway engineers used A.I. to design a completely new Jailbreak system which spreads and angles the Jailbreak blades. Along with stiffening the body, this fancy new design allows the forged face cup to flex more. And thus was born heckin ball speeds. FORGIVING The high strength C300 Maraging Steel used in the face provides outstanding strength and flexibility while the Face Cup provides speed and spin consistency across the face. FLIGHT The forward Center of Gravity (CG) is combined with a new leading-edge to promote a strong ball flight, outstanding spin robustness and consistent shot shape dispersion.
