Q & A

Callaway Men's GBB Epic Sub Zero Driver

Jailbreak Technology Unleashing Faster Ball Speeds

As a company, Callaway seemingly has produced great drivers year after year, but with the advent of Jailbreak Technology, the new GBB Epic drivers, both the standard Epic and the Sub Zero model, have exceeded all others in terms of buzz and excitement. The primary reason for that has been the sizeable increases that Callaway has seen in ball speeds during testing. Keying those increases is Jailbreak Technology, which utilizes two titanium rods within the construction of both Epic drivers that connect the crown and sole to keep the clubface from expanding and losing energy transfer at impact. Also of note, the Epic drivers feature an extremely low, deep CG placement that was enabled by the use of lightweight triaxial carbon in the design and the result is high launch, low spin, and increased MOI. Additionally, a Speed Step on the crown reduces air drag during the swing to help increase swing speed. Both GBB Epic models are 460cc but the Sub Zero has two weight ports in the sole that allow a 12-gram and two-gram weight to be positioned to influence launch and spin rate. With the heavier weight in the forward position, spin rates will drop significantly, while positioning the heavier weight in the back will increase launch and maximize MOI. From an appearance standpoint, the Sub Zero also has a slightly deeper profile, and it has been designed as a lower-spinning head but without sacrificing forgiveness, as its MOI is comparable to the standard Epic. Callaway is also again utilizing its OptiFit hosel, which allows players to adjust loft by +2/-1 degrees and additional draw settings are also available. The GBB Epic Sub Zero driver is available in standard lofts of 9 and 10.5 degrees, it comes at a stock length of 45.5 inches, the swing weight is D4, and custom paintfill options are are also available. It also features stock shaft offerings from Project X, Fujikura, and Aldila in varying weight classes, flexes and launch/spin profiles to suit the needs of any player (see shaft chart below for more details).

Ideal For:

Players of all ability levels who need help in reducing their spin rates. Yes, this is a low-spinning head and typically low-spin heads have been reserved for high swing speed players and lower handicappers. But that’s not the case with the GBB Epic Sub Zero driver. It will certainly benefit a high swing speed player, but the Epic Sub Zero is so forgiving that it will also benefit an average player who spins the ball too much because they have an angle of attack that’s too steep. For those who don’t need help with their spin rate but need assistance when it comes to shot-shaping, the standard GBB Epic might be a better choice.

Jailbreak Technology

Titanium rods connecting the crown and the sole prevent a loss of energy at impact for higher ball speeds from across the clubface.

Jailbreak Technology

Exo-Cage Construction

A titanium cage surrounded by lightweight triaxial carbon enables a low, deep CG placement for high launch, low spin, and max forgiveness.

Exo-Cage Construction

Interchangeable Sole Weights

Players can adjust their launch angle and spin rate as needed depending on where they position 12- and two-gram weights in the sole.

Aerodynamic Speed Step

Callaway’s proprietary Speed Step on the crown reduces drag to help players effortlessly produce more swing speed.

What They're Saying ...

“It’s the fastest driver that we’ve ever made. We had tremendous success with XR 16 but (Epic) blows that out of the water. We’ve never seen ball speeds like this.”

Dave Neville, Callaway Senior Director of Brand Management

“We’re calling it the Sub Zero because the CG is on the (neutral) line, but this is not your father’s pro-style driver. It has the same MOI as the standard Epic, but it’s still very low-spinning at about 500 RPM less. It’s not one that amateurs can’t hit.”

Dave Neville, Callaway Senior Director of Brand Management

“If you need shot shape correction, meaning left or right, the standard Epic is going to work for a lot of players. But if you’re someone who needs trajectory control, whether it’s up or down, the Sub Zero could be a great fit.”

Dave Neville, Callaway Senior Director of Brand Management

“There’s been a lot of talk that this club is going to be a game-changer for people, and having hit it, you can’t argue with that. The kind of numbers we saw in terms of increases in ball speed were really significant.”

Callaway Men's GBB Epic Sub Zero Drivers is rated 4.3 out of 5 by 31.
Rated 5 out of 5 by from Feeling confident again I went through a stretch of the yips with a Cobra Driver; I couldn’t find a fairway to save my life. It seriously had an impact on game, and even my desire to play. I would come up with lame excuses not to play to avoid the embarrassment. In result, I read the reviews on this driver, and thought, “what’s the worst thing that would happen if I purchase this?” After opening this driver from the box, i decided to just take it to my Sunday round without even testing it. Warming up on the range and immediately holding this driver, confidence poured back in me. It has a gorgeous clubbhead, a great stiff shaft, and the grip feels just right. I like that the weighting is not too light, and simply letting the clubhead do the work results in penetrating ball flight and distance. It sounds cliche, but this single club brought the joy in golf back to me.

Rated 5 out of 5 by from Epic SZ 10.5 Best driver I’ve ever owned and I’ve hit them all.. Epic SZ 10.5 with a Tensei ck pro white is a beast, even the stock Fujikura Pro green felt good for a stock shaft. The club is long, forgiving and feels great. I love the color! All my track man numbers were great with this club.

Rated 5 out of 5 by from Great LONG Driver I just bought a Sub Zero driver and have to say what a great Driver. I took it to my local golf store to get fitted with it. I am 67 and was hitting this driver 245-265. I have not hit a driver that long ever. The fitter was surprised that someone my age was hitting the ball that far. I was only 9 inches off center on the track man and my spin rate was at 2000. Thanks Callaway for such a great driver

Rated 4 out of 5 by from Great distance. Not Great Forgiveness I got the Epic back in May. I've played maybe 30-35 rounds with it. The feel is great. And when I catch it clean it's hot. That said, I've left shots well off the mark as well. In my experience there are drivers out there that give you a little more room for error. That said, if you are a lower handicap guy this might be the club for you as it is longer than PING and TaylorMade... at least for me. I will say I don't love the sound. There is a little "ting" to it that I wish it didn't have.

Rated 5 out of 5 by from The ball exploves off the face I have had this driver for three months now and am surprised how hot this club is. I play 6 days a week and have gained at least 10 to 20 yards. All the guys I play with are now buying this driver to stay up with me. Make sure you get fitted. I am 69 and they found the Rogue Max 75 gram stiff shaft works best for my 95 mph swing. The surprising thing is my spin rate has dropped down so I am getting 25 plus yards roll. My club pro also plays Epic and he said the same thing.

Rated 5 out of 5 by from Excellent! My drives have been 20 yards longer, it has more forgiveness when not hit on the center of the face. Well made club!
