Great Big Bertha Epic Driver
GBB Epic represents a paradigm shift in power, speed and ultimately distance.
What makes it Epic?
Epic’s power is based on our innovative new Jailbreak Technology, which fundamentally changes the way the head and clubface behave at impact to deliver more ball speed and distance. The key structural components of a metalwood – crown, sole and face – each bend, flex and rebound at impact. Because they’re connected, they influence each other’s dynamics. Jailbreak Technology creates a remarkably efficient relationship between these components to promote more ball speed across a much larger area of the face.
Jailbreak positions two ultra-light (3g), strong titanium bars behind the face, parallel to each other and connected on either end to the crown and sole. The size, strength and position of each Jailbreak bar work together to reduce how much the crown and sole deflect, forcing the face to take on more of the load created at impact than ever before. This results in faster ball speeds across the entire face from swing to swing, promoting more distance.
But there is more to Epic than just Jailbreak…
Adjustable Perimeter Weighting Technology (APW)
Epic’s increased shot-shape control comes from Callaway’s APW, which, compared to previous models, has a shorter track with a heavier sliding weight. The weight saving from the shorter track allows for this weight to be heavier (17 grams) and helps increase MOI as well as deliver a full 21 yards of shot-shape correction (a 22% increase compared to Great Big Bertha).
Latest Speed Step Technology
Head speed gets an additional boost from the latest version of Callaway’s Speed Step technology, which was originally developed in partnership with Boeing. Located on the crown, the Speed Step improves airflow to encourage more swing speed and distance without extra effort.
Exo-Cage
Epic’s clubhead consists of our latest titanium Exo-Cage combined with 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%, consists of triaxial carbon, with the crown weighing just 9.7g and the sole just 5.8g. That’s the lightest crown ever in a Callaway Driver and of any driver currently on the market.
Epic’s multi-material structure is incredibly light and strong, with exceptional MOI and a low CG that makes it easy to launch the ball high with low spin.
Great shaft options to suit all golfers
With the new Epic drivers, we are offering the most comprehensive stock shaft lineup in Callaway history. We have offerings from the 40g class all the way through the 80g class, in a variety of weights, flexes and torques. Driver and fairway wood shafts are interchangeable for maximum flexibility.
