With Callaway’s new GBB Epic and GBB Epic Sub Zero drivers, the company is relying on a new technology called “Jailbreak” to offer breakthrough performance. With its new fairway woods that have the same names, the company is using a new-and-improved version of a tried-and-true technology, its Hyper Speed Face Cup, to deliver better performance.

Callaway’s new fairway woods used the company’s latest Hyper Speed Face Cup technology.

Now in its fourth generation, Callaway has been using Face Cups to give golfers more fairway wood distance since the company launched its X Hot line in 2013. What’s new with the latest version of the technology is that the Face Cups now have a thinner rim on their inside edge. Callaway says it “flexes and releases more uniformly and efficiently at impact to increase ball speed across the face.”

Here’s what else you need to know about Callaway’s new GBB Epic and GBB Epic Sub Zero fairway woods (both $279.99), which will be in stores January 27.

• The GBB Epic and GBB Epic Sub Zero borrow new technology from Callaway’s new drivers. They use the company’s triaxial carbon fiber crowns, which are 78 percent lighter than the all-steel crowns used on the company’s XR ’16 fairway woods (Epic Crown = 5.8 grams, XR ’16 Crown = 26.5 grams). Callaway used the reclaimed weight to make the fairway woods more forgiving.

• They use new aerodynamics, too. Last year, Callaway debuted a technology developed with help from Boeing to improve the aerodynamics of its XR ’16 metal woods. They were called “Speed Steps,” raised portions on the front of a club’s crown that help golfers swing the clubs faster. Both the GBB Epic and GBB Sub Zero employ Speed Steps.

Callaway’s Epic Sub Zero fairway woods use two adjustable weights (22 and 3 grams) to help golfer’s tweak launch conditions for better performance.

• Two distinct models. Like Callaway’s GBB Epic Sub Zero driver, the GBB Epic Sub Zero fairway woods use two adjustable weights (22 and 3 grams), which allow golfers to position center of gravity more forward or more rearward in the club head. The heavy-weight-forward position is the lowest-spin setting. The heavy-weight-back position creates a higher ball flight and adds forgiveness. The GBB Epic offers an even higher trajectory, as well as slightly more draw bias in its neutral setting.

• GBB Epic Sub Zero Lofts: 13.5 degrees, 15 degrees, 18 degrees

• GBB Epic Lofts: 14 (3+), 15 (3), 18 (5), 21 (7), 24 (9), 20.5 (Heavenwood)

• Both fairway woods have adjustable hosels. Callaway’s Opti-Fit adjustability hosels offer golfers a 3-degree range of loft adjustability, as well as two different lie angles (standard and draw).

• Stock Shaft Options: Project X HZRDUS T800 Green, Fujikura Pro Green, Diamana M+ Green and Aldila Rogue MAX. Several more shafts are available at no extra cost from Callaway.
