Callaway GBB Epic and Epic Sub Zero Fairway Woods: What you need to know

Published

on

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).

    Looks just like the Titleist 915F.

      Minus the visible weight and speed channel.

    From the bottom, the SZ version almost looks like a hybrid.

      Yeah. And it’s got grooves on the face like an iron too

Tour Edge unveils all-new Exotics mini driver

Published

on

Tour Edge Golf has today introduced the all-new Exotics mini driver, engineered to deliver a powerful combination of speed, control, and versatility in the long game. 

The Exotics Mini combines a titanium face with a stainless-steel body in design to balance ball speed with stability and control, creating a versatile option at the top end of the bag. 

At the core of the design is Tour Edge’s proprietary Combo Brazing technology, a high-precision thermal bonding process that seamlessly fuses a titanium cup face to a stainless-steel body into a single, continuous structure. By eliminating energy loss found in traditional multi-piece constructions, Combo Brazing is designed to deliver faster face response, more efficient energy transfer, and a uniquely powerful yet controlled feel.

The multi-material construction also allows mass to be positioned lower and deeper in the head in a bid to increase stability, while the thin titanium face is engineered to maintain ball speed across a wider impact area.

“While the initial goal was to enhance control and versatility in the long game, Combo Brazing ultimately drove measurable gains in ball speed and distance within the mini driver category. In robot testing, we’ve documented higher ball speeds, higher launch, reduced spin, and increased carry and total distance compared to leading models.” – Vice President of R&D Matt Neeley

In addition to distance performance, the Exotics mini emphasizes forgiveness through a heavier stainless-steel body that shifts mass toward the perimeter. This configuration increases MOI relative to traditional all-titanium mini drivers, helping preserve ball speed and directional stability on off-center strikes. Paired with Pyramid Face Technology from the Exotics metalwood line, the design is intended to support consistent speed across the face.

To further enhance MOI, a lightweight carbon fiber crown frees additional mass that is strategically repositioned low and deep in the head in design to improve stability and promote optimal launch with controlled spin.

“We designed the Mini to be about five millimeters shallower than other mini drivers on the market. That change improves playability off the deck. From a clean fairway lie, it can function as a strong 3-wood alternative while still providing control off the tee.” – Tour Edge CEO David Glod

An adjustable hosel system allows for loft and lie tuning to dial in trajectory and shot shape, while a fixed 13-gram rear weight helps stabilize the head through impact to improve dispersion consistency. The Exotics Mini Driver is available in 11.5 and 13.5-degree lofts in right-handed models.

Pricing & Availability

The Exotics Mini Driver is available for pre-order beginning today for $399.99 USD at touredge.com, and will be available for purchase at retail outlets worldwide on May 22, 2026.

Srixon ZXi combo or TaylorMade P7CB/770 combo? – GolfWRXers discuss

Published

on

In our forums, our members have been pitting a Srixon ZXi combo against a TaylorMade P7CB/770 combo. WRXer ‘edutch22’ is on the hunt for a new set of irons and kicks off the thread saying:

“Looking at picking up a new set of irons and think I’ve narrowed it down to Srixon ZXi combo or Taylormade P7CB/770 combo. I am currently a 5 cap and allbeit I feel irons are my weakness. My miss is a little to the toe side. I am decently steep at 4-5 down. Always thought I am high spin but recently on trackman my 7 was spinning at 5800 roughly. 

My question or looking for thoughts on which one would benefit me more from a forgiveness standpoint? Or is there another iron is should be looking at entirely? I only get to play about once or twice a week, if I am not playing a 2-3 day event. Thanks in advance.”

And our members have been sharing their thoughts and suggestions in response.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • manima1: “You just can’t go wrong with Srixon ZXi7.”
  • MattM97: “You have to hit them to know, the V-Sole on the Srixon can be make or break for many.”
  • dmeeksDC: “P7CB is more forgiving for me than ZXi7 because my main miss is low middle and the P7CB still flies and spins great on that miss. These are both really nice irons but I like the P7CB more than the Zxi7 and the P770 (or P790) more than the Zxi5. The Srixons are larger so if that gives you confidence that is the way to go. I don’t feel like I get any benefit from the V-sole and the P7CBs live up to their high Maltby forgiveness rating so the TaylorMades have been great for me.”
