Callaway’s GBB Epic Hybrid: What You Need To Know

GBB Epic hybrid

Callaway has hit it big, literally, with the GBB Epic drivers and fairway woods. Jailbreak technology in the Epic drivers is helping players bomb drives farther than they ever thought they would. And don’t forget about the forgiveness in the drivers and fairway woods. While the GBB Epic hybrid does not feature Jailbreak technology, they do share much of the same driver technology. We dissect the design that results in this great looking hybrid, producing distance with control and versatility.

GBB Epic Hybrid Features

Club Head

Making a driver head out of multiple materials are all the rage these days. Companies use these different lighter-weight materials to boost distance and add forgiveness. Callaway GBB Epic hybrids are no different. They feature a Triaxial Carbon Crown that is 65% lighter than titanium and weighs only 5 grams. Using this carbon creates great weight savings that designers took and placed in other parts of the club head.

GBB Epic hybrid technology

For example, they put an Internal Standing Wave (ISW) inside the head, on the sole. The ISW brings the CG lower. Moving the CG location lower creates distance by lowering the spin produced. It also produces a higher launch and forgiveness by placing weight on the outside of the head. The key component of the ISW is a 35-gram weight consisting of Metal Injected Molded Tungsten. Because the Tungsten is heavy, engineers can concentrate the weight in a precise location to optimize the CG.

All of this is held together with a high-grade steel frame, stabilizing the crown and face. The frame also has weight around the perimeter, maximizing MOI and forgiveness.

Speed and Adjustability

The GBB Epic hybrid has the latest Hyper Speed Face Cup technology, consisting of a thinner rim and more flexible hinge on the clubface. This new face cup gives you higher ball speeds on shots hit across the entire face.

Callaway’s OptiFit hosel lets you easily adjust the loft and face angle. Distance gaps are filled and ball flight is adjusted with a few simple turns of a wrench.

In regards to appearance, the GBB Epic hybrid loosely resembles the Steelhead XR hybrid, with its deep face and square looking toe.  At address, it has a more compact look that better players like. Topping off the club is the Speed Step crown and white Callaway Chevron. The speed steps make the head more aerodynamic advantages, increasing club head speed and distance. Pairing the Speed Steps with the Chevron also helps focus on the center of the club and aids alignment.

The GBB Epic Hybrid comes stock with the UST Mamiya Recoil ES 780 graphite shaft. This shaft weighs 82-89 grams, depending on flex, and has a mid launch. The middle and butt end of the shaft is stiffer for controlling your shot, especially aggressive swingers. 26 custom shafts are available, with 16 having no upcharge.
