Callaway Epic Speed Golf Driver The Epic Speed Golf Driver by Callaway takes speed to a whole new level. It is Callaway's faster Epic Driver Head ever. It is packed with features like Callaway's new Jailbreak A.I. Speedframe to ensure fast ball speeds and increased forgiveness. New Jailbreak A.I. Speed Frame Callaway's new A.I. Speed Frame is used to create outstanding and unrivaled ball speeds across the face. A.I Designed Flash Face SS21 This Flash Face is specifically engineered to work with the Jailbreak Speed Frame. It promotes fast speeds across a more expansive area. Cyclone Aerodynamic Shape Featuring an advanced aerodynamic head construction, higher head speed and lower drag is created, creating faster ball speeds. As well as this, the taller ribbon and flatter crown are engineered for a precise and more aerodynamic shape that adds more speed to your swing. Advanced Composite Design Callaway has used their proprietary Triaxial Carbon Design for a larger portion of the crown and toe instead of using a titanium crown. This has saved them over 16g of weight, which has been redistributed to enhance forgiveness.
