Callaway introduces Great Big Bertha Epic Driver

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

“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.

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.

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. That’s the lightest crown of any Callaway driver currently on the market.

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 (a 22 percent increase compared to last season’s Great Big Bertha) to dial in straighter, more accurate flight while maintaining high MOI (or Moment of Inertia).

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.

Four premium, Tour-proven stock-shafts are available, distinguished by weight class and each engineered to promote a formidable combination of speed, power, stability, feel and control: Project X HZRDS Green, MRC Diamana Greenboard, Fujikura Pro Green and Aldila Rogue Max. A long list of custom after-market shafts is also available.

The GBB Epic driver will be available from January 27, 2017 and priced at AUD$729.99 and NZD$849.99.

Also announced today, Callaway Golf will 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 starting January 27, 2017.
