Ping claims smaller is better with its new G400 drivers

Published

on

In general, the larger a driver measures in size, the more forgiving it will be. On the flip side, the smaller it measures, the faster you’ll be able to swing it because it will have less drag through space. For golf club engineers, the puzzle is to design a driver that has the ultimate forgiveness, but it also needs to reduce drag, or air friction, to produce the maximum speed possible.

Speed and forgiveness often oppose each other, but Ping believes it has engineered a driver that reduces the tradeoff between them.

Ping’s new G400 drivers measure only 445 cubic centimeters — 15 cubic centimeters smaller than the now-standard 460-cubic-centimeter driver — but they’re even more forgiving than their predecessors, the G30 and G, both of which were industry leaders in forgiveness among their contemporaries. According to Ping, the company has managed 0.75 mph more club head speed and a 3 percent increase in MOI (a measure of forgiveness) with its new G400 drivers compared to its predecessors.

“We didn’t feel pressure to hit 460,” a Ping representative said. “Volume was a free variable for us… and we made it even more forgiving than the G. To be clear, this is not a Tour-only driver; it’s for everyone.”

To boost forgiveness, Ping looked to improve its Dragonfly technology, which it introduced with the G drivers. As you might remember, the Dragonfly design is highlighted by raised portions on the rear of the crown that look something like bear claws. Their overall goal is to remove weight from unwanted areas. In the G400, Ping engineers were able to eliminate even more weight from the Ti-8-1-1 crowns, and the soles, too. The result was a smaller club head that created a 15 percent reduction in drag, according to Ping, leading to the increase in club head speed.

“we’re continuing to reduce drag, which is becoming harder to do.”

You may ask: “Instead of using Ti-8-1-1 titanium, why doesn’t Ping simply use carbon fiber like everyone else if they want to lower CG?”

According to Ping, the titanium material it uses is much better for casting, and it allows the crowns to be made as thin as Ping feels is necessary. Company representatives also say that carbon fiber crowns don’t save weight as efficiently as some may think due to the welding, epoxy, and other accomodations that are necessary when using the material. Ping prides itself on the casting process — Karsten Solheim, the founder of the company, was a pioneer in casting in the golf industry — and says it has created the thinnest crown in company history with the G400 drivers.

By removing weight from where it’s not needed, Ping engineers were able to relocate it into the condensed back weight on the sole. Its copper-colored, and made of both elastomer and stainless steel. There are also tungsten weights — made of nearly pure Tungsten, according to Ping — in the driver soles that are located in different spots on the three different models for the three different trajectories they produce.

  • SF Tec (10, 12 degrees): Tungsten is placed in the heel for 10-12 yards of draw bias, according to Ping.
  • Standard G400 (9 and 10.5 degrees): Tungsten is placed at the extreme rearward of the sole for maximum forgiveness and wide-spread appeal.
  • LS Tec (8.5 and 10 degrees): Tungtsen is placed more forward than the standard model, shifting center of gravity (CG) toward the face. This reduces spin, and encourages a penetrating flight. It also adds about 3 yards of fade bias. Ping says the G400 LS Tec is about 300 rpm lower spinning than the G LS Tec with the stock Alta CB shaft, and up to 500 rpm less spin with the Tour shaft, which 0.5 inches shorter.

The faces of the new Ping drivers are now made from T9S+ instead of the T9S material of its predecessors, they and have variable face thickness (VFT) to boost ball speeds on off-center hits. The new material is stronger and has 20 percent greater stretch, therefore, it can be made thinner and produce more ball speed at impact.

Along with performance improvements, the company has also addressed concerns about the sound of its predecessors, which produced a higher-pitched sound than golfers wanted, especially the LS Tec. With a new virtual analysis system, Ping simulated sound frequencies without actually building a prototype. Using the new tool, Ping was able to dial in the exact sound it was looking to produce with each of the driver heads. This process is revolutionary for the company, it says, which used to build prototypes and test sound on the range via headphones. Ping engineers describe the sound of the new G400 drivers as “powerful, but muted.”

Further enhancing the overall experience of the drivers, Ping engineers also worked on visual aspects of the club head to better appeal to the eye of golfers. You’ll notice Ping’s Dragonfly technology on the crown now wraps around the back edge. Ping calls this an “infinity edge.” According to Ping, this aesthetic softens the edge and is more appealing to golfers at address. The G400 drivers also have Turbulators, or raised portions on their crowns, that sit directly behind the face. They have been thickened up, and dots have been added to the back of the crown. Neither of these changes have any aerodynamic qualities, but improve the look of the drivers, according to Ping.

Another interesting aesthetic change to the Ping G400 drivers is their stock shafts, which use a special paint application that looks different at address than it does on the shelf. By using paint that refracts light in different ways, the Ping Alta CB (counter-balance) shafts have a copper color when they’re looked at fro face on, but they appear to be all black at address. Ping also offers a Tour shaft as a stock offering, which comes in two weights (65 and 80 grams) and has stiffer profile for high-speed golfers. Aftermarket shaft offerings, which carry a $75 upcharge, include the Project X HZRDUS 75 (5.5, 6.0 and 6.5-Flex), Aldila X-Torsion (R and S Flex), and Mitsubishi Kuro Kage 60. Ping’s G400 drivers will sell for $435 per club with stock shafts, and they become available on July 27.

    I hit the G400 on two different launch monitors over the last two weeks. I was very, very impressed both times. I am sure there is a lot of truth in the statements saying that driver head technology has maxed out, given the rules restrictions. However, different drivers have different looks, feels, and sounds. For me, the G400 looks great at address (very compact, muted black), feels tight and solid, and the low thud sounds better than any driver I’ve ever hit. As for launch monitor numbers, the G400 with the Tour 65 shaft easily beat the Epic and M2 and was marginally better than the M2 Draw. The G400 (for me) beat all the other drivers hands-down in the subjective categories (look, feel, sound) and performed equally well or better in the objective categories (spin, carry, accuracy).

    It’s a fine looking club and I like the idea of a smaller head. No hope for me though, as I’m a long way behind and still gaming a TM r7 425cc and W/S Ti Td5 385cc

    Looks nice but can’t picture it performing better on course than their last couple drivers. After drinking the marketing koolaid for the first time in years and bagging a gbb epic (best of the bunch for me), the penny dropped that these 2017 drivers are only slightly better than the early 460cc heads. A farkled out 2007 driver w/ nice shaft, shortened to 44″ and correctly lead taped swing weight will still be damn nice.

          Hey McPickens, yep took an old 9.5deg, 45″ R5 that I replaced two drivers ago (never dawned on me back then to modify it), down to the practice fairway recently. Hit it not far off the professionally fit 10.5deg Epic which is in turn about as easy to hit as my 3w. Shortened and lead weighted, the r5 would probably be a better club than I thought at the time; will be a little careful next time I’m tempted by the marketing brigade.

    There’s nothing wrong with this. But there also is no discernable improvement over previous versions. The numbers claimed are tiny. There’s more variability in your swing than is found in this driver.

    How does this driver compel people to leave their current drivers (from Ping or other manufacturers)? How does this driver exceed its current-year competitors?

    Real advances in drivers:

    — Taylormade introduces the metal driver
    — Callaway Big Bertha pushes larger designs with bigger sweet spots
    — Titanium drivers
    — Adjustable weights
    — Adjustable everything else

    Because the USGA limited COR to .830 and the clubhead to 460cc, there’s not much room for manufacturers to innovate. Movable weights have added some potential distance gains, but even those are maxed out.

    The key to success with drivers–just as it is so with irons–is not in the latest version of the same technology. Rather, it is the fitting of the right clubs (and specs) for each player. Buying these Pings off the rack will not help you get there–beyond the help of the dot.

      I agree, especially with the Ping line. They are all pressured to come up with the next greatest, longest, straightest clubs or no one will upgrade.. and to be clear, I dig the Ping line.

      But, not adjustable like the other brands and not that much different than the G line. Not offering adjustability isn’t betraying some golf trust… it’s just not wanting to spend the money to upgrade your current offering.

      Knowing these are 2 year product cycles, I wonder if this line up is strong enough to pull from what Callaway and Taylormade are offering. If not, it could be a long 2 years for Ping.

    Read some good reviews by people that have had the club for a few weeks now. I know I read somewhere that the small dots helped air to flow tighter to the head and have less turbulence.
    I like that the head is smaller love the understated looks. I don’t need a new driver right now but I will check these out. Ping makes honest equipment.

    So-called improvements in golf gear are really not needed every year. It’s all about marketing and driving sales. Golf course sizes and dimensions were pretty much standardized in the last century (and before). If manufacturers want to make the game easier for the common man (like me), fine, just make the clubs easier to hit. Don’t “improve” clubs and the ball to the extent that courses have to continually be re-designed and stretched to accommodate the latest technology.

      “It’s all about marketing and driving sales.” Well duh…These companies must sell their products and make a profit to survive. They don’t make the clubs out of the goodness of their hearts. It’s a business.

    I’ve got a better idea. I’m gonna bring out my Chicago Classic Perssimon out of hibernation. It’s like 300cc’s. Outta be able to swing even faster as I watch the ball fly into the rough. Why don’t these OEM’s bother mentioning how long the driver shafts are? Momentum is really built up by length of shaft and swing arc. The club head is just merely a passenger in the swing.

    • FFS

      Jul 11, 2017 at 2:57 am

      No, you have to have mass at the end of the stick too, to have any effect on momentum. You can continuously lengthen the clubs all you want, there’s going to be a point of diminishing returns when you can’t swing it around on time. It’s better to have the proper balance of head weight and shaft length than just going lightheaded and light swing arcing with longer lengths, as long you can handle the heavier head set up

    Jul 10, 2017 at 12:21 pm

    Count me as excited and intrigued. The only redeeming thing to me about a 460cc driver is that science tells me that it is straighter/more forgiving than a smaller head. I would love to swing a smaller head.

    First thing I will want to hear about, however, is the sound. Current Ping drivers are indeed notoriously straight. But they sound like garbage cans. I hope these sound different.

  16. Clay

    Jul 10, 2017 at 12:06 pm

    Why so many negative comments every time a new driver comes out? And Ping only releases them every two years, it’s not like they just dropped a new driver on us last quarter. Maybe sitting behind a keyboard creates a road rage effect for some people.

    I personally think it looks fantastic and am looking forward to a sound/feel improvement. Not a Ping homer, my only Ping club is a Ketsch putter, but I have hit the G and my only complaint was sound and feel. Performance was outstanding.

      Same here mr b. May sound strange to some, but I’m not looking for more forgiveness than I get with the G30 LS, so I didn’t go to the G series, still want a driver I can work at least a little. Of course the G400 does look interesting, could always use the three wood when I need to work the ball.

Korea’s FreeFlex shaft proves that lightning strikes twice

Published

on

The biggest obstacle to success is said to be a closed mind. If past innovators had not been bold in trying new things and testing conventions, we may still be playing with featheries and hickory shafts. Thanks to their pioneering ways, the game was able to evolve into the wonder that it is today and I am grateful for all the advantages I have enjoyed.

According to a recent YouTube video uploaded on TXG, one such innovative product they have tested in recent years is the Autoflex shaft. Despite the shocking pink color and a high price tag, the whippy shaft from a relatively unknown Korean manufacturer has won over a significant number of golfers with its promise of distance and accuracy while going easy on the body. The shaft opened up a whole new shaft category by itself, and after almost three years it is still pretty much the only fighter in the ring.

So why haven’t more companies been entering this niche pioneered by Dumina? The market is clearly there. Surely, there must be other manufacturers capable of putting out their own versions? Is KHT really something that no one else can figure out? Whatever the reason, there hasn’t been any serious contenders making a run at the champ. Until now, that is.

The premium ultralight shaft category has a new entrant in FreeFlex shaft… from South Korea, where else?

Ottophlex?

In the absence of established shaft makers, I did see a lot of individuals on various online forums trying to find their own version of a cheaper Autoflex. Affectionately dubbed as OttoPhlex, I have come across several impassioned posts where golfers have detailed their endeavors to find an effective replacement. To their delight, many have said their bargain shafts also produced noticeable distance gains while retaining accuracy.

That’s just awesome. I think it’s great that Autoflex generated such an interest in golfers to turn over every stone in our search for all the advantages we can get. One caveat, however, seems that an OttoFlex shaft that worked wonders for one guy sprayed the ball all over the place for another. Of the various OttoPhlex shafts I have seen online, I have yet to see a true contender that worked for a wider group of golfers like Autoflex.

In a way, Autoflex reminds me of Floyd Mayweather, Jr., the unbeaten boxing champ. Love him or hate him, one can’t deny that his boxing skills are effective. Similarly, whatever Korea Hidden Technology may be, it simply works and deserves its just dues.

One unique attribute to FF’s water color shaft is that no two shafts are the same.

A Korean Lightning Strikes Again

Now a promising new challenger has entered the ring to contend for the title of the ultra-light premium shaft. The contender, also hailing from South Korea, goes by the name of FreeFLexx (OttoPhlex was taken, obviously) and comes with an extraordinary spec sheet. And to save you readers some time, the shaft is nothing short of amazing.

Dr Seung-jin Choi, founder and CEO of SJ (Special Joy) Golf Engineering Lab, is a lifelong golfer/entrepreneur with an impressive resume and some pretty unconventional ways of thinking. With a PhD in materials engineering, he has over 30 patents in various fields, including materials engineering, architecture, and industrial design and 12 patents (and growing) in golf clubs and shaft design. His appetite for knowledge is only rivaled by his keen ability to adapt and apply them effectively to his research and inventions.

Ever since AF came on the scene, I’ve been waiting for other OEMs to offer similar tech and performance to the AF at a lower price tag so that it can be more accessible to a wider audience. Err… let me return to that idea later. 

When I first met Dr Choi, I thought I’d stepped into a golfer’s version of Dr Frankenstein’s laboratory. I’d love to mention some of the jaw-dropping golf innovations he is working on, but an embargo dictates otherwise. But I guarantee you will hear more of his mind-blowing creations soon. Just remember I said it here first.

Care for some ultra-light carbon putter shafts that can make any putter stand upright on its own? Then RolyPoly is for you. Just one of many zany things in the works at SJ Golf Lab.

Opening the box, I half-expected to see the color pink and breathed a sigh of relief at the sleek matte black carbon weave design. But aesthetics aside, the shaft had to first check all the requisite boxes for me to even consider it a true contender to the AF. After all, this weight class is not for just any AF wannabes or conventional senior-flex shafts.

To be clear, I am a big fan and user of AutoFlex shafts. But seeing the FreeFlex shaft check all the same WOW factor boxes gave me goosebumps. “Has AF finally found a match in the FF?

From Theory To Reality

According to Dr. Choi, FF technology is a totally different animal from KHT in concept and manufacturing method and is solidly rooted in measurable and verifiable science. It all began over two years ago with a single question, “Which part of the swing most determines the performance of a golf shot?”

After consulting hundreds of top amateurs and pros along with top professors in sports sciences, he determined that an effective downswing transition was key to long and accurate shots. This led to his next question, Can a shaft be made to provide golfers with a repeatable and effective downswing transition for better impact and ball control?”  With this specific goal in mind, Dr Choi embarked on his research, drawing on his 30+ years of golf experience and scientific background. To many people’s surprise, he was able to prove some pretty eye-opening facts along the way.

I’ve often said that some of golf’s commonly-held conventions should be re-examined lest we may have overlooked anything. With new materials and applications for its use being discovered each year, I definitely think new ‘breakthrough’ discoveries are possible. AF and FF are just the tip of the iceberg.

Before I begin, let me also state that I am an absolute novice when it comes to shaft engineering and manufacturing. I still don’t know what KHT is about, and I am just as ignorant about FreeFlex technology (FFT) as it, too, is veiled in secret and awaiting a patent. So bear with me as I try to explain the idea and innovation of FFT, as translated from speaking with the inventor.

The waggle test that put AF on the map can be seen in the FF as well

FreeFlex Tech – The New Secret Sauce?

Prototypes of the FreeFlex shafts were first launched in April 2022 exclusively in Korea and were tested extensively among the pros and the club fitting community. Soon, word of mouth began to spread among the pros, who were taken aback by the performance benefits of FF. More interestingly, the FF also came under scrutiny from the sports academia as well as the club fitters, most of whom were absolutely skeptical that the shaft can do what it claimed. And Dr Choi was more than happy to show the science and the research to back up his work with FreeFlex.

Having listened to the inventor, however, I can’t really fault them for being doubtful. After all, Dr Choi’s questions and unconventional thinking challenged many of the established notions that I also thought were rock solid. For example, can a single shaft exhibit two different flexes? That is, can one side can be stiff to promote accuracy while the other side is flexible to add an extra kick for more distance?

When everyone said that’s impossible, Dr Choi said “I’ll show you. Let me boot up my computer.”

“We have developed a unique shaft to which the pronate and supinate principles have been applied by considering not only the swing toque acting upon the shaft; but also in considering the warping moment and bending torsional moment to optimize Impact and MOI.” – Dr. Seung-jin Choi, inventor of FreeFlex Technology

Before all this, I thought I knew the relationship between a shaft’s flex and torque. Namely, a low torque corresponds to a stiff flex and vice-versa, and more flex may lend itself to more distance, but at the risk of less accuracy. Despite what I thought I knew, Dr. Choi informed me that this was not always the case. In fact, he found that torque and flex (CPM) can be independent of each other and that a 35g shaft with 170cpm can have a torque as low as 2.0. That’s even lower (and firmer feeling) than an extra stiff tour shaft!

In explaining how he can manipulate torque and flex in any combination desired, the actual math and science went straight over my head but I was offered a simpler explanation. Imagine that one side of the shaft has a limiter on it, while the other side has an accelerator. The limiter prevents the shaft from twisting and bending past a certain threshold to increase the chances of the shaft returning back to its original position for accuracy. In turn, the accelerator would activate on the downswing to increase club speed for added distance. As improbable as it sounds, this is the basis for FreeFlex.

But hey, we all know that anyone can talk the talk and all is for naught if it can’t perform. So can FF really put its money where its flex is?

Battle Of The Flexes

Over the past three years, many golfers have given testimony to the effectiveness of AF and I have also enjoyed my own AF to mostly good ends. While I’m not the foremost expert by any means, below is my own assessment of the similarities and differences that I have observed between AF and FF.

Overall, I found that FF not only was comparable to AF in both distance and accuracy, but it also offered three key differences which may be welcomed by golfers hesitating to pull the trigger on the pink bomber.

Observations

The first difference was the swing weight recommendation for both shafts. The AF 405 and FF 405 had similar weights (45g raw) and flex (190cpm), but the swing weight was totally different at C8 and D1.5, respectively.

From the beginning, AF shafts have frustrated many a golfer trying to get the swing weight down, since the average driver heads were too heavy. As a result, it required switching to lighter head weights or removing them altogether. In addition, certain brand club heads were not suitable for AF, and sometimes the overall driver build length had to become shorter as well. Needless to say, this irked a lot of players and golf fitters who had never encountered such hurdles in their drivers. It is a testament to AF’s performance that so many golfers have put up with it at all.

In comparison, the FF shafts seem more accommodating in this department. The recommended SW for the 38-series is at D2~D5, which should make club fitting all that much easier for a wider variety of driver heads.

FF shafts feature the weight, CPM, and torque. The bow and arrow symbolizes the idea of FreeFlex Tech, as the shaft reacts to even a small amount of energyacted upon it, much like a bow.

The second key differentiator between the two is swing mechanics. By nature, I am more of a swinger than a hitter, and AF suits my swing super well. With a slow and measured backswing and a smooth downswing transition, I have gained nearly 20 yards over my past conventional shaft. As such, many golfers have testified to benefit from slowing down and smoothing their transitions to unlock AF’s performance. However, for golfers with an aggressive or quick transition, the AF proved difficult to tame, which has led many to believe that AF is only suitable for smooth swingers.

FreeFlex, on the other hand, claims that its shafts can be swung effectively regardless of the type of downswing transitions. From my own limited testing with three friends in this regard, I can say that FF did fare better than AF for hitters with a more aggressive swing. More specifically, FF shafts were noticeably more resistant to the left side and kept hard hooks to manageable draws to keep the ball in play more often. Dr. Choi also added that the shaft is less prone to break, as it uses higher grade carbon content over its counterpart.The third big difference noted by most testers is that the FF shaft feels more stable throughout the swing. Keep in mind that feel is subjective, and “stable” here is only referring to the feel and not the actual shot result. From my experience, the AF shaft is soft and malleable on both the backswing and the downswing, which took me a few weeks to get used to and trust that the head will return to square.

In contrast, FF has the same low CPM but the shaft is noticeably firmer especially on the downswing, giving a feeling of stability. I was better able to feel where the club head was at all points of the swing, and that gave me a slight edge in confidence on the money shots. 

The three aspects were the biggest differences that were reported by FF users, and I can also agree on the observations. On a Trackman, my current AF was on average longer by 2m with a 4% smaller dispersion, while the longest single drive by each shaft favored the FF at 239m to 231m.

What gave me pause was that while AF has been my trusted gamer for the past 2+ years, I only hit the FF a couple of times since receiving it. And despite the short duration and novelty, FF performed just as well for me as AF, with the alluring promise of further fine-tuning and additional improvements to be had. Welcome to the weight division, FF.

Measurements on the butt end makes it convenient to trim the shaft to desired length.

Price And Availability

Unfortunately, FreeFlex tech shafts are currently available in Korea for the time being, though an English website is in the works at www.freeflexshaft.com for February. According to the company, offline retailers and custom fitters will soon be available to offer FreeFlex in three color options; matte carbon black, glossy carbon blue, and a one-of-a-kind custom watercolor design. 

All these ultralight and performance-enhancing factors do not lend themselves to low pricing either. The retail price of the FF driver shaft is set at $650, and while it is much higher than most premium shaft offerings on the market, it is nearly 20-percent less in comparison to the Autoflex at $790.

Aside from multi watercolor, FF comes in matte and glossy carbon weave tinged in blue color that looks amazing outdoors

For a limited time starting in February, SJ Golf is also taking applications from professional golfers and reviewers to test the FreeFlex demo shafts. Applications and inquiries can be sent to [email protected] and the company will notify the results individually. 

And there you have it. The FreeFlex shafts have arrived to join the party and I can’t wait to see who else joins this exclusive club. It would be great to see who rules this ultra-lightweight division, but no matter who is crowned champion, it will be us golfers who will be the ultimate winners.
