Callaway to release Sub Zero driver, with the company’s lowest CG ever
The chase for a lower center of gravity (CG) has taken Callaway below the neutral axis line with its new XR 16 Sub Zero driver. According to Callaway, the driver is made for better players with fast swing speeds, and boasts the lowest CG of any Callaway driver ever designed.
Imagine the neutral axis line as a line drawn backward, perpendicular from the center of the club face, as illustrated above. While most drivers have a CG above that line, the XR 16 Sub Zero, which measures 440 cubic centimeters, boasts a CG below it.
The XR 16 Sub Zero was lower spinning than Callaway’s Big Bertha Alpha 816 DBD driver in the company’s robot and player testing.
Drivers with low-CG positions can help golfers lower their spin rates, allowing those with fast swing speeds to achieve a more penetrating trajectory that can increase distance. The most notable example is Phil Mickelson, who is currently using the Sub Zero driver on the PGA Tour.

To achieve the Sub Zero’s lower CG, Callaway gave it a new crown, which is made of a “Carbon Triax” material. According to Callaway Senior R&D manager Evan Gibbs, the new crown is made from “fabric, or laminate,” which is different from the chopped fibers that are used to make the carbon fiber crowns for Callaway Great Big Bertha and Big Bertha Alpha 816 DBD drivers.
All three drivers use the same molding technique for their crowns, however, the Carbon Triax material is thinner and lighter, allowing weight to be displaced lower and deeper in the club head.
Compared to Callaway’s XR 16 and XR 16 Pro drivers, the XR 16 Sub Zero will not have as high of a moment of inertia (MOI), a measure of ball speed retention or forgiveness on off-center hits, due to the concentration of weight low and forward in the club head. That’s not ideal for golfers who struggle to make consistent contact, but skilled golfers can use the lower CG position to hit longer drives.
The XR 16 Sub Zero is also adjustable, allowing players to fine-tune their trajectory with a 10-gram and 2-gram interchangeable weights that are placed in opposing weight ports. Moving the heavier weight forward makes for a penetrating, lower-spinning trajectory, while moving it rearward setting will provide a higher launch and more forgiveness, but slightly raise spin in comparison.
Callaway’s XR 16 Sub Zero driver (9.5 degress, RH Only) will be available for $449.99 on April 15 with the choice of 20 premium shaft at no upcharge.

Did Rory McIlroy inspire Shane Lowry’s putter switch?
Editor’s note: This is an excerpt from a piece our Andrew Tursky originally wrote for PGATour.com’s Equipment Report. Head over there for the full article.
The timing of Lowry’s putter changeup was curious: Was he just using a Spider putter because he was paired with McIlroy, who’s been using a Spider Tour X head throughout 2024? Was Lowry just being festive because it’s the Zurich Classic, and he wanted to match his teammate? Did McIlroy let Lowry try his putter, and he liked it so much he actually switched into it?
Well, as it turns out, McIlroy’s only influence was inspiring Lowry to make more putts.
When asked if McIlroy had an influence on the putter switch, Lowry had this to say: “No, it’s actually a different putter than what he uses. Maybe there was more pressure there because I needed to hole some more putts if we wanted to win,” he said with a laugh.
To Lowry’s point, McIlroy plays the Tour X model, whereas Lowry switched into the Tour Z model, which has a sleeker shape in comparison, and the two sole weights of the club are more towards the face.
Lowry’s Spider Tour Z has a white True Path Alignment channel on the crown of his putter, which is reminiscent of Lowry’s former 2-ball designs, thus helping to provide a comfort factor despite the departure from his norm. Instead of a double-bend hosel, which Lowry used in his 2-ball putters, his new Spider Tour Z is designed with a short slant neck.
“I’ve been struggling on the greens, and I just needed something with a fresh look,” Lowry told GolfWRX.com on Wednesday at the 2024 Wells Fargo Championship. “It has a different neck on it, as well, so it moves a bit differently, but it’s similar. It has a white line on the back of it [like my 2-ball], and it’s a mallet style. So it’s not too drastic of a change.
“I just picked it up on the putting green and I liked the look of it, so I was like, ‘Let’s give it a go.’”

Webb Simpson equipment Q&A: Titleist’s new 2-wood, 680 blade irons, and switching to a broomstick Jailbird
With seven career wins on the PGA Tour, including a U.S. Open victory, Webb Simpson is a certified veteran on the course. But he’s also a certified veteran in the equipment world, too. He’s a gearhead who truly knows his stuff, and he’s even worked closely with Titleist on making his own custom 682.WS irons.
On Wednesday at the 2024 Wells Fargo Championship, I caught up with Simpson to hear about his experience with Titleist’s new prototype 2-wood, how Titleist’s 680 Forged irons from 2003 ended up back in his bag, and why he’s switching into an Odyssey Ai-One Jailbird Cruiser broomstick putter this week for the first time.
Click here to read our full story about Simpson’s putter switch on PGATOUR.com’s Equipment Report, or continue reading below for my full Q&A with Simpson at Quail Hollow Club on Wednesday.

GolfWRX: It seems like you’ve been a little all over the place with your irons in the past six months or so, and now going back to the 680’s. Is that just a comfort thing? What’s been going on with the irons?
Webb Simpson: Titleist has been so great at working with me, and R&D, on trying to get an iron that kind of modernizes the 680. And so the 682.WS took the T100 grooves, but kinda took the look and the bulk and the build of the 680’s into one club. They’re beautiful, and awesome looking. I just never hit them that well for a consistent period of time. It was probably me, but then I went to T100’s and loved them. I loved the spin, the trajectory, the yardage, but again, I never went on good runs. Going through the ground, I couldn’t feel the club as well as with the blade. So last week, I’m like, ‘Alright. I’m gonna go back more for…comfort, and see if I can get on a nice little run of ball striking.’
So that’s why I went back.

OK, that makes sense. I know you had done some 2-wood testing recently. Is that in the bag right now?
It’s like day-by-day. I used it at Hilton Head every day. Valero, I used it one round. And this week, me and my caddie will do the book every morning, and if it’s a day where we think we need it, we’ll just put it in and take the 3-wood out. I love it because it’s a super simple swap. Like, it doesn’t really change much.
Yeah, can you tell me about that club? I mean, we don’t really know anything about it yet. You know? I haven’t hit it or anything, obviously.
It has grooves like a 3-wood. Spin is perfect. And it’s honestly, like, everything is in the middle of a 3-wood and driver number. Trajectory, spin, carry, all of it. So, a Hilton Head golf course is almost too easy to talk about because, you know, there, so many holes are driver 3-wood.
Valero, our thinking was we had two par-5’s into the wind, and we knew that it would take two great shots to get there in two. So instead of hitting driver-driver, we just put it in. And I used it on those holes.
Hilton was a little easier because it was off-the-tee kind of questions. But Colonial will be a golf course where, you know, there’s a lot of driver or 3-woods. It’s kind of like a backup putter or driver for me now. I’ll bring it to every tournament.
So it’s, like, in your locker right now, probably?
Well, it would be. It’s in my house [because Webb lives near by Quail Hollow Club, and is a member at the course.] It’s in the garage.
Oh, yeah, that’s right. Do you know what holes you might use it out here if it goes in play?
Potentially 15, depending on the wind. Second shot on 10. Could be 14 off the tee. The chances here are pretty low (that he’ll use the 2-wood). But, like, Greensboro would be an awesome club all day. I’m trying to think of any other golf courses.
There’s plenty that it’ll be a nice weapon to have.
It’s interesting, the wave of 2-woods and mini drivers. Like, it’s just really taken off on Tour, and all the companies have seemed to embrace it.
Yeah. The thing I had to learn, it took me, like, at least a week to learn about it is you gotta tee it up lower than you think. I kept teeing it up too high. You need it low, like barely higher than a 3-wood. And that was where I got optimal spin and carry. If you tee it up too high, you just don’t get as much spin and lose distance, I don’t know if that’s just a mini driver thing.
And you obviously have a Jailbird putter this week. What spurred that on?
Inconsistent putting. I’m stubborn in a lot of ways when it comes to my equipment, but I have to be open minded – I just hadn’t putted consistently well in a while. And I’m like, ‘Man, I feel my ball-striking coming along. Like I feel better; for real, better.’
If I can just get something in my hands that I’m consistent with. Being on Tour, you see it every year, guys get on little runs. I can put together four to five tournaments where I’m all the sudden back in the majors, or in the FedExCup Playoffs. You can turn things around quick out here. I’m like, ‘Man, whatever’s going to get me there, great.’
My caddie, David Cook, caddied for Akshay at the Houston Open and he putted beautifully. Then, I watched Akshay on TV at Valero, and he putted beautifully. And, I’m like, ‘I’m just going to try it.’
I’ve never tried it for more than a putt or two, and I just ordered what Akshay uses. It was pretty awkward at first, but the more I used it, the more I’m like, ‘Man, it’s pretty easy.’ And a buddy of mine who’s a rep out here, John Tyler Griffin, he helped me with some setup stuff. And he said at Hilton Head, he wasn’t putting well, then tried it, and now he makes everything. He was very confident. So I’m like, ‘Alright, I’ll try it.’”
And you’re going with it this week?
Hundred percent.
Alright, I love it. Thank you, I always love talking gear with you. Play well this week.
Thanks, man.

Uhhh, Cobra King LTD beat them to the market with the zero CG driver. Plus, the Cobra LTD has nice forgiveness unlike what Cally is claiming is lost with the Subzero. LTD for the win!

“bro i hit it like 20* 1000rpm 380 yds.”
one release later: “not forgiving enough.”
another release later: “20* 1000rpm seems about right”

I don’t see the big deal. Ping has a low spin driver as part of the G series this just looks like a low spin XR 16.

To all you nay sayers. I have been buying every new driver that has come out from callaway and taylormade and have really embraced the new technology. My average drives are between 680 and 700 yards and golf has become very easy for me.

Finally they made a perfect driver until the next one. Just a joke. No wonder equipment makers are struggling. They flood the market, more supply then demand. Why would anyone buy at full retail from cally, tmag when in a few months it is on the clearance shelves.

Another driver that people on WRX will go crazy about because it is low spin but nobody will be able to hit. Like the Slider 430
