Callaway engineers can hardly conceal their glee when they talk about their latest driver releases, the Great Big Bertha Epic and the Great Big Bertha Epic Sub Zero. That is largely because both clubs employ a technology called Jailbreak, which Dr. Alan Hocknell, the company’s senior vice president of research and development, lauds for the way it “creates a new and remarkably efficient working relationship between the face, crown and sole to promote faster ball speed across more of the face to give the golfer more distance.” He describes Jailbreak as groundbreaking and claims it represents “an epic shift” in the way the clubhead and face behave together.
Performance in these drivers, he adds, is also enhanced by the use of multi-material clubheads as well as weighting systems and Speed Step aerodynamics. The two driver models are made to be complementary, with the Epic Sub Zero marrying the same tour performance characteristics of the Epic, only
with higher moment of inertia for greater forgiveness.
According to Hocknell, Jailbreak incorporates two slender titanium bars positioned parallel to each other behind the face and connected to the crown and sole. The size, strength and position of each bar create a new dynamic relationship between the crown, sole and face. The result, he says, is more speed across a much larger area of the face.
As for the clubheads, they are made of Callaway’s new titanium Exo-cage outfitted with crown and sole panels made of triaxial carbon. Both clubs feature adjustable weight systems, albeit different types. The Epic employs a sliding, 17-gram weight that can deliver a full 21 yards of shot-shape correction, while the Epic Sub Zero uses a pair of interchangeable weights, 12 and two grams in size, respectively, that are positioned at the front and back of the sole – and that can be utilized in tandem with the Optifit hosel so players can adjust spin and launch angle.
