Two titanium rods connect the crown to the sole behind the face, which Callaway says stiffens the head for faster ball speeds. An exo-cage body structure is paired with the company’s lightest ever carbon crown to maximise forgiveness. A Speed Step crown improves aerodynamics for quicker club speeds and you get a 17g sliding perimeter weight offering up to 19m of shot shape correction.
It’s designed to be the “mainstream” Epic model (the low-spin Sub Zero version is aimed at better players). Yet our test pro preferred this one – and got better numbers from it! He loved the dull, muted sound that comes from that “Jailbreak technology” stiffening the head and directing more energy back towards the ball. The ability to align the sliding perimeter weight with his impact position produced an extra 1.2mph of ball speed and five yards of carry distance over the Sub Zero, too. Both amateur testers got better numbers from the Sub Zero, but the Epic racked up a very tidy third place tie for average carry distance across all three testers, which just goes to validate this new face tech.
