Callaway to release Sub Zero driver, with the company’s lowest CG ever

Published

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.

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

Slab city on the Korn Ferry Tour — Lead Tape Report

Andrew Von Lossow

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.

Joel Thelen

Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.

First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.

Mitchell Meissner

Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.

@Lamosteve began:

Can you name every set of irons you’ve owned? Here’s mine

Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red
Taylor Made R9s
PING i20
PING iE1
Taylor Made M6

Our members in the forum have been offering up their own collections. 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.

macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”
JimmyC59: “MacGregor Jack Nicklaus Triple Crown. Palmer The Standard. Still play these.”
