Callaway Big Bertha Fusion drivers and fairway woods

Published

As we all know, the USGA limits drivers to a certain size (460 cc), and COR (coefficient of restitution), which is 0.83. Since companies, such as Callaway, have already reached those limits — or somewhere very close to those limits — improvement continues elsewhere to design drivers that can positively impact golfers.

While many new drivers on the market use adjustability features to accomplish this, Callaway’s new Big Bertha Fusion drivers, and fairway woods, use advanced composite materials, head shaping and weight placement with the goal of making the most forgiving clubs possible.

From a company that’s been using composite materials for over a decade, Callaway’s Big Bertha Fusion drivers and fairway woods introduce a new material called “Triaxial Carbon,” combined with a unique, high-MOI driver head shape that stretches weight back away from the face.

According to Callaway, triaxial carbon is 65 percent lighter than titanium and 35 percent thinner than the forged composite used in recent drivers from the company. Because of how the materials in the carbon composite are woven, the triaxial carbon is stiffer, allowing the driver to be constructed thinner without losing strength.

Callaway uses the new material in the crowns of both the drivers and the fairway woods, and in the soles of the drivers, too.

Read more about the drivers and fairway woods below, which will be available in stores on September 30, and join the discussion about the clubs in our forums.

Big Bertha Fusion Driver

In the driver, an “exo-cage” made of aerospace-grade titanium holds the triaxial carbon material, which is used in both the crown and on the toe and heel of the sole.

By using triaxial carbon, Callaway was able to save 35.4 grams of weight that was repurposed low and back for higher MOI (moment of inertia), a measure of forgiveness, and in the heel of the driver, making it more draw-biased. This also allowed Callaway to lower CG, thus reducing backspin and raising launch.

The crown consists of two parts: A chopped fiber forged composite in the front, and triaxial carbon in the rear

According to Callaway, the drivers have up to 17 percent higher MOI than the XR 16 drivers. Like the XR 16 drivers, the Big Bertha Fusion drivers also have Speed Steps — the fruits of work with Boeing — on their crowns for more speed than a smooth surface, due to the aerodynamic quality of the design.

The driver also includes Callaway’s OptiFit hosel that allows users to adjust loft independent of face angle settings.

Stock shafts will be a UST’s new Recoil shaft made for drivers, and Mitsubishi Rayon’s new Diamana Red Board. Consumers will be able to choose from the 45.5-inch stock shaft option, and a 44.5-inch shaft that has a slightly heavier weight in the back of the driver head to adjust for swing weight.

The drivers carry a MAP of $399, and will be available in 9, 10.5 and 13.5 degree lofts.

Big Bertha Fusion fairway woods

Like the Big Bertha Fusion drivers, the fairway woods also have the lighter triaxial carbon in their crowns. In total, the crowns weigh a feathery-light 5.8 grams, compared to the XR 16 crowns — made from stainless steel — that weigh 26 grams, according to Callaway.

With a lighter crown, Callaway was able to reposition weight low and back in the club for higher launch and higher MOI, and lower CG.

The fairway woods come with a Hyper Speed Cup Face for higher ball speeds on off-center hits, and the Speed Step crown for higher club head speed and less drag. The sole shape was also designed to reduce turf interaction, thus improving versatility for shots hit off the ground.

The Big Bertha Fusion fairway woods will sell for $249, and come available in 3-, 5- and 7-wood options.

Looking down on the club it looks like the shape of a TM club that came out 5-7 years ago. R9 I think it was. I like a more traditional looking club like the XR.

  You’re thinking of the R7 Limited, the red one. But Callaway has had this shape before also.

I hit these the other day along with the new irons and hybrids and they are most certainly not the best looking clubs I’ve ever seen. Meaning, if this club were a gigolo, it’d have to be very good with its fingers.

I was a little taken aback by the recoil wood shaft, I said, “that’s the shaft my grandpappy plays in his irons, do you have anything in 92 grams???” But, there was nothing else to try.
I play my driver at 44 7/16, so it wasn’t perfect, but it was CLOSE. The best thing I can say about it is that for a game improvement club it doesn’t spin a ton, so if you mostly hit drop-kick, high blocks–this could be the club for you.
The irons are going to be the real star of the show for callaway this year though with the steelhead and the Bertha replacement that’s coming.
Everyone should try them unless they’re like me and still Baggin’ a set of ping eye 2 berrillz, blue dot, 1-PW. Holla at me, 1987.

“new material”, that’s hilarious. K2 was making skis with this material in the 1980’s. It’s marketing BS (I have a marketing degree). These guys will say anything to make a buck!!!

  I’m willing to bet the article/statement for Callaway is implying that the material is new to golf equipment. By your logic the only “new materials” are ones that haven’t been discovered by man yet…..don’t be so literal Zipper.

While the 44.5 option is nice…it won’t be in stock at most stores. So this benefit is mostly moot unless the store salesman knows he can get it in a shorter, more controllable length. Enough with the 45.5″ and 46″ driver off the rack specs. They don’t work for the true average player.

I came here thinking, “yet another Callaway release”, but these actually do seem to be different. Besides, offering a 44.5 option should be celebrated, even if it is these guys.

Haven’t we taken steps backwards since the Fusion FT-3 Driver? That club had the entire body made of carbon, not just the sole and crown. This allowed them to move 44 grams around inside the head to wherever they wanted.

The problem with carbon composite is you have to use glue to attach it, so all the weight you save is wasted in glue. Notice the weight on the head is just “12 grams.” Yes there was some weight saved, piece for piece, but they probably only moved about 6 – 9 grams around, which can still make a difference in driver design, but also the reason why all titanium drivers are still competitive. Love the marketing though!

44.5 right out the store wow, hopefully others try to copy this. These 46.5″ drivers are getting ridiculous.

At least they are offering this. I prefer shorter drivers; play mine at 44.25″ – lead tape on bottom to make up weight change. My distance does not seem affected by the shorter length, better dispersion and hit the center 90% of the time. More should experiment with different driver lengths. I know Tom Wishon has a chart which gives recommended lengths based on height, wrist to floor, etc.

“Consumers will be able to choose from the 45.5-inch stock shaft option, and a 44.5-inch shaft that has a slightly heavier weight in the back of the driver head to adjust for swing weight.”

Putters that never made it: Check out some of the best tour builds that didn’t make the cut

Published

2 weeks ago

May 18, 2026

Alistair Cameron

Arguably, the best perk of being a professional golfer on the PGA Tour is the ability to request or even just be handed pretty much any club you could think of. It happens more often than you think, usually with putters around the practice green from one event to the next. Come Wednesday, the Tour bags lining the edge of the putting surface become resting places for fallen flatsticks that never made the cut.

So let’s take a look at some of the best we’ve seen out on Tour this year that never made it to the competition. (You may notice none of Hideki Matsuyama’s custom Scotty Cameron putters made this list. There are too many.)

Let’s start with this custom Damascus Milled Odyssey Rossie made for Ryo Hisatsune. Featuring a single line and the short-slant hossel, we’ve seen plenty of Number 7 and jailbird heads featuring the Damascus Milled insert, but this is the first and only one we’ve spotted in a Rossie. Hisatsune primarily putts with an Odyssey Black Series iX #9, but we have seen him recently with a TaylorMade TP Collection SOTO, so there could be potential that the Damascus Milled Rossie could end up in the bag.

Everyone wants to be Cameron Young right now. We’ve had Justin Thomas and Tom Hoge both game the Scotty Cameron 9.5R prototype. Well, for the PGA Championship, Brooks Koepka nearly joined that list after requesting the same style of putter, with the full-length alignment line. But the Scotty Cameron reps took the request a step further and made one specially for Koepka with a Teryllium insert, similar to one in his previous Newport 2 gamers. The reason why this one didn’t go into play, though? Because it was too heavy.

Harry Hall was the third-best putter on Tour last year, so when Bettinardi made him a custom proto, you know it was going to be good. The custom BB28 blade features VDF face milling, a custom-welded single-bend shaft, and the owner’s initials – HH – on the sole of the putter. Hall, who usually games an Odyssey O-Works #7 W, has dabbled with a TaylorMade Spider Tour X already this year. Maybe there’s a chance this Bettinardi might make his bag.

Honestly, this one doesn’t need a description. It’s Kieth Mitchell’s custom Scotty Cameron Napa. One Scotty Cameron face stamp, two Scotty Dogs, two Scotty Cameron 7-Point Crowns and one Circle T. That is all. Oh, except for the Cashmere Cameron headcover.

Finally, and just for fun, how about we pour one out for this TaylorMade Spider Tour X made for Scottie Scheffler in its new torched finish. It’s unlikely we’ll see a putter change anytime soon from the best golfer in the world. In fact, he hit just two putts with it on the Harbour Town practice before going back to his trusty gamer.

Which of Tiger’s major winning irons are your favorite? – GolfWRXers discuss

Gianni Magliocco

In our forums, our members have been discussing their favorite major winning irons used by Tiger Woods. WRXer ‘golferdude54’ kicks off the thread saying:

“Mizuno MP 14/29. Titleist 681T. Nike Forged Blades. TaylorMade P7TW.

Among these irons that helped Tiger win 15 majors, which is your favorite in terms of looks?”

And our members have been naming their favorites and why in response.

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

SwingBlade: “I prefer the early blades he played and the more recent TM TW’s especially because after Tiger had his major behavioral setbacks, part of Nikes support payback was making Tiger play a Nike putter and cease using his beloved uniquely customized Scotty putter.”
ProjectX: “This (Nike Forged Blades) and there’s not even a close second.”
