Great Big Bertha Epic introduced by Callaway

Callaway Golf Company has introduced the Great Big Bertha Epic, a driver that incorporates Callaway’s new Jailbreak ball speed technology. Jailbreak changes the fundamental way the head behaves at impact to promote more distance for every type of player.

The key structural components of a driver – crown, sole and face – deform at impact. Because they’re connected, they influence each other’s dynamics. Jailbreak incorporates two slender titanium bars positioned parallel to each other behind the face, connected to the crown and sole. The size, strength and position of each bar creates a new dynamic relationship between the crown, sole and face. The result is a profound change in how the head, as a whole, behaves at impact, resulting in more speed across a much larger area of the face.

“Jailbreak Technology 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,” said Dr. Alan Hocknell, Callaway’s senior vice president of R&D.

Epic’s clubhead consists of Callaway’s new aerospace-grade titanium Exo-cage outfitted with a crown and sole panels made of triaxial carbon, an extraordinarily light and strong composite material developed by Callaway. Nearly half of the head’s surface – 46 percent – consists of triaxial carbon, with the crown weighing just 9.7g and the sole just 5.8g.

Epic’s increased accuracy is rooted in Callaway’s Adjustable Perimeter Weighting technology, a feature that allows golfers to easily adjust the club to fit their swing. Compared to previous Callaway Drivers, Epic’s track has been redesigned and the sliding weight has been increased to 17 grams, both for good reason: to deliver a full 21 yards of shot-shape correction to dial in straighter, more accurate flight while maintaining high MOI.

Head speed gets an additional boost from Callaway’s proven Speed Step technology. Devised with the help of aerospace experts, the Speed Step, located on the crown, improves head aerodynamics for more speed and distance.

GBB Epic Driver availability begins at retailers nationwide from January 27, 2017 with an RRP of £469. Callaway Golf will also bring a complementary Great Big Bertha Epic Sub Zero Driver, which marries Tour performance characteristics with forgiveness in a true paradigm shift, and a full line of GBB Epic Woods. These clubs will also be available from January 27, 2017.
