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.

In our forums, our members have been discussing Mini-Drivers and accompanying shafts. WRXer ‘JamesFisher1990’ is about to purchase a BRNR Mini and is torn on what shaft weight to use, and our members have been sharing their thoughts and set ups in our forum.
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.
- PARETO: “New BRNR at 13.5. Took it over to TXG (Club Champ but TXG will always rule) in Calgary for a fit. Took the head down to 12, stuck in a Graphite Design AD at 3 wood length and 60g. Presto- numbers that rivaled my G430Max but with waaaaay tighter dispersion. Win.”
- driveandputtmachine: “Still playing a MIni 300. The head was only 208, so I ordered a heavier weight and play it at 3 wood length. I am playing a Ventus Red 70. I play 70 grams in my fairways. I use it mainly to hit draws off the tee. When I combine me, a driver, and trying to hit a draw it does not work out well most of the time. So the MIni is for that. As an aside, I have not hit the newest BRNR, but the previous model wasn’t great off the deck. The 300 Mini is very good off the deck.”
- JAM01: “Ok, just put the BRNR in the bag along side a QI10 max and a QI10 3 wood. A load of top end redundancy. But, I have several holes at my two home courses where the flight and accuracy of the mini driver helps immensely. Mine is stock Proforce 65 at 13.5, I could see a heavier shaft, but to normal flex, as a nice alternative.”

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
