Three Callaway GBB Epic drivers appear on USGA Conforming Club List
Three new Callaway drivers have appeared on the USGA’s Conforming Club List: the GBB Epic, the GBB Epic Star and the GBB Epic Sub Zero.
Callaway isn’t commenting on the new Great Big Bertha (GBB) drivers at this time, so we can’t officially confirm or deny any details about the new drivers. We do anticipate that one or more of the driver models could be in play this week at the Hero World Challenge in the Bahamas, however, where they will be permitted for us. We also can point out a few things based on the USGA’s black-and-white photos.
GBB Epic
GBB Epic Star
Based on the photos, it appears the GBB Epic and GBB Epic Star are virtually identical, with the exception being the lack of an adjustable hosel on the GBB Epic Star.
Both drivers appear to use a technology called “Jailbreak,” which is highlighted on the front of the driver’s sole. The technology is rumored to connect the sole and crown of the drivers, adding reinforcement that improves energy transfer.
On the other end of the sole is a sliding weight that enables golfers to select a draw, fade or neutral trajectory bias. There are also what seem to be carbon fiber inserts on the soles of all three driver models. Carbon fiber is lighter than titanium, and its use presumably enhanced the ability of Callaway engineers to optimize the weighting of the driver heads for improved performance.
GBB Epic Sub Zero
Instead of a sliding weight track, the GBB Epic Sub Zero has two adjustable weights — one on the front of the sole, and one on the back. That reminds us of Callaway’s XR ’16 Sub Zero driver, which is the company’s current ultra-low-spin driver. It design targets better golfers, and was used in 2016 by Phil Mickelson.
The Sub Zero got its name from its center of gravity position (CG), which Callaway says is below the neutral axis line, or “sub zero.” The XR ’16 Sub Zero uses a what Callaway called a Carbon Triax Crown, an extremely thin, lightweight composite material on the top of the driver that the company said enabled its sub zero CG location.

Below are the results of GolfWRX member voting for the 2025 best driver, along with the vote percentage for each club.
Best driver of 2025: The top 5
5. Callaway Elyte Triple Diamond: 6.02%
Callaway’s pitch: “For golfers looking for a fast, forgiving, yet workable driver, the Elyte Triple Diamond features a tour-inspired shape and is the preferred model by most Callaway tour players.”
You can read what other golfers are saying about the driver in the GolfWRX forums, and see our launch piece here. Shop the Callaway Elyte Triple Diamond here.
4. Ping G440 Max: 6.86%
Ping’s pitch: “The most forgiving G440 model, MAX has a hotter face to generate speed and distance, and a lighter overall system weight with a longer shaft (46″) for faster clubhead speed, higher launch and longer carries. The Free Hosel and Carbonfly Wrap crown save weight to create our lowest CG ever and increase forgiveness while contributing to a more muted, pleasing sound.”

3. Ping G440 LST: 9.53%
Ping’s pitch: “LST is an especially good fit for faster swings, offering less spin and more control with a penetrating trajectory. A hotter face, lighter overall system weight and longer shaft (46″) deliver more speed and distance while maintaining tight dispersion.”
@phizzy30: “Not a fan of Ping drivers in general, but 440 LST takes the cake. It’s super forgiving across the face for a low spin head, looks and sounds good and the ability to make it play neutral or slightly fade biased through the hosel settings is very appealing.”

2. Titleist GT3: 16.55%
Titleist’s pitch: “The GT3 Driver offers Titleist’s boldest combination of power and personalization through adjustable performance. Dial in the CG Track to your frequent contact location to make your biggest drives even bigger while taking total control over flight and shaping.”
@mrmikeac: “I’ve been Anti-Titleist for years and years and years (outside of Vokey, of course). With that being said, HOLY BEGEEZUS the GT3 driver is an absolute NUCLEAR MONSTER! This thing blew my G430 10K Max out of the water in every single category. Forgiveness is the biggest thing that stands out of me, the 3 model has always been one of the less forgiving models in the past but this GT3 can take bad shot after bad shot and still end up in the fairway, I think a ton of that has to do with the adjustability, it’s actually effective. Feel and sound is perfect, that solid crack is so addicting to hear and when you hit it out the screws this thing can absolutely bomb it. Titleist, I’m sorry for doubting you. You have converted me.”

1. Titleist GT2: 22.91%
Titleist’s pitch: “Delivering impressive distance from any impact point, the Titleist GT2 Driver extracts maximum performance through a forgiving design. Get the stability and added confidence of a high-MOI driver without sacrificing speed.”
@DTorres: “The Titleist GT2 has proven to be the best driver of the year. Packaged in a classic profile, GT2 perfectly balances performance and forgiveness while consistently being a high performer across all categories.”

A lot of the comments, so true. I buy a new driver amount every 3 years. I typically buy a model that’s one year old and half the price of the original in very good shape.

The Korean YouTube video showed these in detail. I’m sure cally will try their best to have it pulled, but it’s still out there. Search for it on naver or another Korean search engine.

I can’t believe no one has speculated that the bonded hosel design was made for Tiger. Are the “Tiger is buying TM” rumors so strong that no one wants to start a new rumor about Tiger signing with Callaway? Fine, I will start the rumor. The GBB Star is made specifically for Tiger and will not go to market. I have zero evidence but I know some people that know some people that robbed some people and they said it is true.

The Epic Star has my attention. Will this be a non-adjustable model that is in the $399 range? Would they want to compete with possible Fusion sales?

Jailbreak technology!??! What is that?? Does it mean if you pay someone to “unlock” it you remove the USGA COR restriction!??!

Man, I just saw a Mizzy Fast Track at GolfMart for like $30.
If Callaway says this technology is a game changer then I’m going back to get that Mizuno tonight!
