PowerBilt's latest driver reaches a new low (in a good way)

In equipment circles, the push for drivers with extremely low spin is a more common topic of conversation than Tiger Woods' return. Nearly every driver introduced in 2015 has a center of gravity (CG) lower than in past generations. The latest to do so is PowerBilt's new Air Force One DFX Tour.

loop-DFX-TOUR-DR-Sole-450.jpgThe club has a nine-gram weight angled forward in the front of the sole. The result is a lower, more forward CG compared with the company's regular DFX MOI driver to produce tee shots with less spin.

The DFX Tour ($300, 8.5, 9.5, 10.5 degrees) also uses pressurized nitrogen gas in the clubhead to reinforce the metal walls without needing added material for support (the valve houses the nine-gram weight). This helps designers create a more flexible, thin face for more ball speed.

Nearly 10 percent of Japanese golfers are playing with non-conforming equipment

Non-conforming equipment may already have been used in tournament play by amateur golfers in Japan. That's part of a statement provided to Golf Digest by the Japan Golf Goods Association. The organization announced last month its support of the manufacture and distribution of non-conforming equipment in the Japanese marketplace. 

The JGGA says there is "an increasing number" of non-conforming clubs being distributed in the Japanese market "because there is a demand for them among golfers." Its research says that 8.7 percent of golfers in Japan were using non-conforming equipment, and that the demand for non-conforming equipment is even higher in South Korea.  

The JGGA says the intent with last month's announcement was not to recommend non-conforming equipment but to clarify its place in the market. "Even now there is a concern that non-conforming clubs are being used by amateur golfers in local tournaments as they or the tournament organizers do not recognize those clubs as such. Our press release intends to improve the current situation to the extent practicable."

The JGGA says it wants to guide manufacturers "to provide consumers with a clear indication and appropriate explanation when they sell those products to avoid any confusion by consumers." 

Though it took nearly six weeks for the organization to respond to a series of questions sent by Golf Digest via email, the JGGA also reiterated its position that non-conforming equipment strengthens interest in golf. The responses can read somewhat convoluted, but the ultimate direction is clear. The JGGA says, "There is a clear desire or preference among amateur golfers in general for more distance from a driver shot or more back spin from an iron shot that makes a ball stop or come back on a green as professional players do. JGGA believes that it will contribute in the healthy growth and revitalization of the Japanese golf market to create an environment in which each golfer may choose and use golf equipment that matches his or her unique goal and needs."

The JGGA says it offered a proposal to the R&A to regulate non-conforming equipment but the "R&A did not accept our proposal." The JGGA says it is concerned that without any clear distinctions in the marketplace about non-conforming equipment "it could result in the further unregulated, disorganized expansion of the non-conforming golf club market."

In fact, the JGGA is stopping short of endorsing equipment that fundamentally alters the playing of the game, preferring instead that non-conforming equipment remain within the range of clubs that "were previously considered as conforming but became non-conforming only due to the tightening of the equipment rules over the past decade or so."

The R&A, USGA and several U.S. golf manufacturers have not commented on the JGGA's statements.

Japan manufacturers endorse non-conforming clubs

juggernaut_sole_1.jpg
The Japan Golf Goods Association, the trade organization for golf equipment manufacturers in Japan, today announced that it would support the distribution of non-conforming golf equipment. 

“JGGA believes that it is desirable for the stimulation of the golf market to have a wide variety of golf equipment available in the market from which all types of golfers may choose in order to find one that really fits their respective purposes and needs, hoping that more and more golfers will enjoy playing golf as a result of such improvement in the golf equipment market,” an English translation of the JGGA statement reads.

“From this point of view, JGGA has left it to the judgment of each member company whether to manufacture and/or sell golf equipment that doesn’t fully conform to the specifications set forth in the Rules of Golf promulgated by R&A.”

A recent study by Golf Datatech and Yano Research Institute of Japan, the world’s two leading organizations studying the global golf retail market space, Japan is the No. 2 country in golf sales in the world with 24 percent of the global golf market. The JGGA sponsors the Japan Golf Fair, Japan’s version of the PGA Merchandise Show, which will be held Feb. 13-15 in Tokyo.

In its statement the JGGA acknowledges that an influx of non-conforming equipment “could create confusion among golfers and tournament organizers. JGGA considers it very important for the healthy development of the industry that all relevant parties make efforts to prevent consumers from buying nonconforming equipment without knowing that it is nonconforming, and to avoid any confusion or trouble due to the inability of tournament organizers to determine the conformity of each equipment at the tournament site.”

The JGGA is advocating that products be clearly marked as nonconforming, although it has not indicated what specific efforts or product labeling will be made. Its main motivation seems to be to cater to golfers seeking more enjoyment without performance limits imposed by the rules.

Several U.S. manufacturers contacted for this story have either declined comment or not returned inquiries. The R&A also has not returned an e-mail request for comment.

U.S. manufacturers have not embraced non-conforming equipment, and while the JGGA's Japan Golf Fair routinely has nonconforming equipment on display, no major U.S. company has introduced non-conforming equipment to date. Smaller companies have introduced non-conforming clubs and balls, like Hireko, which last year introduced a 515 cubic centimeter driver called the Juggernaut (above). After much talk about non-conforming equipment at the last two years' PGA Shows, fueled largely by former TaylorMade CEO Mark King who launched a grow-the-game, alternative rules golf initiative Hack Golf last year with great fanfare, there was very little discussion on the topic this year. 

This news from the JGGA clearly reopens the discussion.

“For the most of amateur golfers, nothing give[s] more pleasure than long driving distances and control of a golf ball on the green with a back spin as professional golfers do,” the JGGA statement reads. “That is why quite a few of golfers are still using and wanting nonconforming golf equipment and why nonconforming golf equipment is still available on the market in response to such demand. Some golfers may be using or buying nonconforming equipment without knowing that they don’t conform to the Rules.”

What’s not clear is just how much advantage non-conforming equipment might provide for amateur or recreational golfers, or whether there's expressed interest in playing clubs that don't adhere to the rules. A 2014 survey by Golf World suggested less than a quarter of golfers surveyed would be interested in "a nonconforming driver that promised an extra 15-20 yards." John Spitzer managing director for equipment standards of the USGA told Golf World last year, “To think nonconforming clubs would somehow increase participation, I don't see that. It's not 1,000cc drivers or a ball that goes 30 yards farther that's going to grow the game."

But it is clear that there are certain elements within golf equipment manufacturing willing to go down the road of selling clubs outside the rules. In that stame Golf World story, Bob Philion, president of Cobra-Puma Golf, told Golf World, "There is a sense of urgency in the industry, whether from our competitors or the PGA of America, to be less intimidating and more fun. Do I think nonconforming drivers will be out there in 10 years? I do. Three years? I do. I think the street signs for the game aren't positive enough for someone not to try it." 

The JGGA’s statement clearly is endorsing manufacturers be free to take a more relaxed approach to the rules.  It concludes, “Through a variety of actions and initiatives, JGGA is committed to providing a market environment where all golfers are able to choose and use the most appropriate golf equipment for every situation.”

Callaway's "X" line gets its broadest launch with XR's nine new products

xr-driver-sole-b.jpgCallaway’s “X” family of products goes back to the late 1990s and the introduction of the X-12 irons 17 years ago. Back then, the story was the revolutionary thinned out cavity construction and extreme low center of gravity on the cavity back oversized iron. Big news that almost immediately set sales records for the company.

But there may never have been a broader range of new technologies in the history of the X family than there is this year.

Callaway today announced nine new products under the new XR moniker, including two drivers, three fairway woods, two hybrids and two irons. The theme consistently across each category seems to be speed. Whether it’s the lighter face in the XR drivers or the metalwood-like face cup on the traditionally-shaped, cavity XR irons, Callaway’s engineers are chasing new ways for golfers to produce both more ballspeed and, in some cases, more clubhead speed. 

But the breadth of offerings (at least two styles in the driver, fairway wood, hybrid and iron offerings) also seems focused on helping individual golfers better dial in the size and shape of head that’s going to produce the best results for them.

Evan Gibbs, Callaway's senior manager of product performance in metalwoods, was referring to the new XR fairway woods, but his summary could easily apply to the whole XR family: “We tried to understand where golfers use these clubs, how they use them and how to most effectively design a club for that situation.”

All clubs in the XR line are expected to begin to be available in shops by Feb. 20.

XR/XR Pro drivers
xr-driver-back-2015.jpg
The natural question with Callaway introducing its fourth and fifth drivers since August is how could it be any better. But Callaway is not shy about making its case with the new XR and XR Pro drivers ($350/$400). First, there’s a move toward improved aerodynamics. The XR features a pair of distinct speed steps at the front part of the crown designed to reduce drag. It also helps boost swing speed potential through a lighter overall weight (just TK grams on the XR model). According to Gibbs, the lighter weight features draw bias to help average golfers square the face and fight a slice. 

Second, the face on the XR is 10 percent lighter, and the center of gravity (CG) is 17 percent lower than last year’s X2 Hot. Similar to this fall’s Big Bertha Alpha 815 drivers, it utilizes a ribbed structure toward the front of the crown and sole to help increase the area of the face that yields the fastest ball speeds. Third, the XR Pro uses a forged composite crown to produce the lowest CG of any Callaway driver ever. 

“The advantage of having forged composite is you can create very aerodynamic shapes, which typically means the crown apex is higher and further aft, without paying a cg penalty,” Gibbs says. “You have such a lightweight material that you can pull the crown up and shape it to be aerodynamically efficient without the cg going too high.”

Each of the four lofts in the standard model (9, 10.5, 12 and 13HT) and two in the Pro (9, 10.5) include Callaway’s eight-way adjustable loft hosel. The hosel allows the user to reduce loft by one degree or increase it by one or two degrees and then also independently alter lie angle. One further benefit of the XR driver is its lighter weight. 

XR/XR Pro fairway woods, hybrids
The distinct shape differences in both the XR fairway wood and hybrid lines grew from how players of different ability levels use the clubs. The fairway wood line includes three varieties (standard, Pro and 3Deep) and the range accommodates 10 lofts, including the only stock 11-wood from a major manufacturer ($230 for the XR, $240 for the XR Pro and XR 3Deep). 

xr-fwy-pro-sole-a-2015.jpg
“The standard XR was designed with an emphasis put on performance and utility from the fairway,” Gibbs said. “The Pro version was designed with more of an equal usage from the tee and fairway in mind. And the Deep version was designed with an emphasis of performance off the tee.” 

The club’s primary technology is a redesigned cupface that’s thinner and lighter to help boost ballspeeds and lower the CG. The internal weighting updates the wave-like feature toward the front of the sole, pushing more weight forward while still freeing up the area low on the face. This helps to reduce spin and improve ballspeeds for shots hit low on the face. 

The XR and XR Pro hybrids offer similar differences to the fairway woods in size and shape (the Pro is decidedly more compact to appeal to better players), and the cupface and low CG design have been updated. Gibbs says the CG on the XR is 46 percent lower than the X2 Hot, while the CG on the XR Pro is the lowest ever for a Callaway hybrid. 

xr-iron-hero-2015.jpg
XR/XR Pro irons
The problem with creating irons with face structures that attempt to flex like drivers is that they end up looking and feeling more like drivers than irons. That means hollow construction irons that often are oversized and excessively wide-soled. 

Callaway’s effort with the XR iron line is to incorporate the flexibility in the face produced by its cup face design but wrap the technology in a more traditional, cavity-back iron shape. Both the XR and XR Pro feature a two-piece construction where the face cup wraps over the entire perimeter of the face and is fused to the sole and back of the iron. This allows for more control of how thin the face can be made to improve rebound across a greater area.

“The benefits of the 360 face cup that we see in an iron are very similar to what we see in a fairway wood or a hybrid,” said Luke Williams, senior director of  product strategy in fitting and irons. 

Within the cavity is an internal wave-like structure that improves performance on low-face impacts and lowers the center of gravity. The XR ($800) features more offset, while the XR Pro ($900) uses a thinner top line and narrower sole.

Ping boosts G30's long game, adds new short-game clubs, too

PING_Cadence_Anser2.jpgAnser2_Heavy.jpgPing enjoyed plenty of success on the professional tours and in the marketplace with long game clubs like the G30 driver this fall, but it's starting the new year off with a focus on where golfers spend the majority of their strokes: the short game. While there will be a line extension to the G30 driver family with the new G30 LS Tec, it's the Glide wedges and Cadence TR putters that are the big splash.

PING_Glide1.jpg
Glide wedges
The groove rollback’s greatest effect may have been in inspiring equipment companies to rethink every possibility when it comes to generating more spin. The latest example might be Ping’s new Glide wedges, which feature a new chrome-plated finish to improve spin potential. According to Ping engineers, the finish increases the metal’s hydrophobicity, or a substance’s tendency to repel water. A more hydrophobic wedge face is going to provide cleaner contact in wetter conditions like the rough and dew-covered fairways, and the Glide’s chrome-plated finish tests out as more hydrophobic than the dark blast finish of last year’s Tour wedges. The Glide ($130, 13 lofts, three sole options) also matches groove edges and angles to each loft to improve full-shot spin on the lower lofts and chip and pitch shot spin on the higher lofts. The new Dylawedge grip is three-quarters of an inch longer to make it easier for players to comfortably choke down on the grip on partial shots.

On the PGA Tour, Bubba Waston, Hunter Mahan and Billy Horschel have put the Glide wedges in their bags.

Cadence TR putters
With the growing enthusiasm for counterbalanced putters, it’s becoming clear that weight is a solution for balky strokes. But while the extreme weight of a counterbalanced putter may help the shakiest of moves, Ping is suggesting that finding the right weight is a real key in putter fitting for all strokes. 

To that end, it’s rolling out the new Cadence TR line of putters, which give golfers the choice of two standard head weights. Ping engineers have studied data from thousands of putting strokes submitted through its iPing putting app and determined that there are two main stroke tempos. Quicker tempos benefit from a standard to lighter head weight, while slower moves produce better results with a heavier head weight. 

Each of seven models in the Cadence TR line feature two heads (there’s also an eighth model that’s counterbalanced). The standard weight models (340-355 grams) generally feature an aluminum insert, while the heavier heads (365-388 grams) use steel inserts for a 25-33-gram difference in the two heads. 

Ping_G30LS.jpg
Each also features a revised version of Ping’s TR groove pattern on the face. The new faces feature not only variable depth grooves as previously, but now add variable width to improve initial ballspeed compared to the Scottsdale TR groove. The putters are available for pre-order this week and will be in stores next month, starting at around $170. Already Mahan (Anser 2) and Angel Cabrera (the counterbalanced Anser 2 CB) have put the putters in play at the Hyundai Tournament of Champions.

G30 LS Tec
The new G30 driver, the LS Tec ($350), is aimed at higher-speed players looking for an even lower-spinning option. 

The driver features the same turbulator crown elements to improve aerodynamic efficiency, as well as a similar emphasis on high moment of inertia for stability on off-center hits. 

Ping engineers say the LS Tec's center of gravity is slightly forward of the standard G30 to produce less spin. It will be offered in 9- and 10.5-degree lofts, each with an adjustable hosel that can tweak loft by plus/minus 1 degree.

TaylorMade makes twin driver debuts with R15 and AeroBurner lines

TaylorMade's Nov. 13 launch of two new drivers -- the movable weight, multi-level adjustable R15 and the lightweight, swingspeed-focused AeroBurner -- makes the same case about what kind of driver you should buy that the company first made nearly a decade. The idea, which hearkens back to previous twin-driver introductions like the R9 and the Burner SuperFast, is that there are two kinds of golfers looking for two types of clubs: the technician and the bomber.

The technician is about dialing in precise launch conditions and navigating his way around the golf course strategically, with planned routes and trajectories. The bomber prefers high, far and straight, a less subtle approach that might be phrased as "swing first, ask questions later."

But both new drivers will build on the company's primary metalwood technologies of a center of gravity positioned more low and forward for less spin and improved energy transfer. Both also will feature a channel in the sole designed to enhance the way the face flexes for improved ballspeed all over the face. 

loop-taylormade-R15-Driver-350.jpgThe R15, which will be made available in both white and black versions, is the technician's driver. It features a sole channel with two independently movable 12.5-gram weights. The sole channel, or "speed pocket," is similar to the predominant feature on the successful SLDR drivers. It allows players to position weight in draw or fade settings, as well as positioning the weights in either a middle position or extreme heel and toe locations for improved stability. Compared to the SLDR, the R15's sole channel has been shifted slightly closer to the face (12 millimeters) to contribute to the way the face flexes at impact. That movement forward also helps further push the center of gravity forward. According to the company, more than 75 percent of the clubhead's total mass is in the front of the driver.

The R15 also utilizes an updated version of the company's adjustable hosel, which now accommodates 12 settings and a loft range of plus/minus two degrees. It's available Jan. 9 ($430, 9.5, 10.5, 12, 14 degrees) and will be offered in both a 460cc and 430cc head size. Golfers can pre-order the R15 starting Dec. 12.

The R15 line includes fairway woods ($280, 15, 16.5, 19, 20.5 degrees) and hybrids ($220). The adjustable fairway woods feature the same sole opening but with one sliding 25-gram weight to effect a draw or fade bias. Like the driver, the adjustable hosel can be set to one of 12 positions at plus/minus two degrees of loft. The hybrid or Rescue features a more compact 99cc head size and the neutral bias preferred by better players. 

loop-taylormade-AB-Driver-350.jpgAlthough the R15 offers plenty of adjustability, some players simply want distance -- and at a more palatable price. That's where TaylorMade's debut of its AeroBurner line fits in. 

According to Brian Bazzell, TaylorMade's senior director of product creation for metalwoods, AeroBurner "drastically improved the performance of the sole's speed pocket and significantly improved the aerodynamics to deliver maximum speed" compared to the successful RocketBallz line from a couple of years ago.

To assist with the aerodynamics, the club features a small fin -- present on drivers, fairway woods and hybrids—in the heel area of the club to reduce drag. A raised center on the crown, as well as a more rounded toe, also are designed to help get the club through the air more efficiently. 

In the driver ($299), the speed pocket is twice as large as on the JetSpeed model. By not adding adjustability, the pocket could extend across the entire sole. Also helping speed is an overall lightweight design -- the total weight is less than 300 grams -- with a 50-gram Matrix Speed Rul-Z shaft.

The fairway woods ($229) and hybrids ($199) continue the company's pursuit of woods with low, forward centers of gravity, as well as a sole slot, something the company has been focusing on since its RocketBallz line. 

The hybrids, called AeroBurner Rescue, also have the speed pocket as well as a shaft length that has been shortened a half-inch from the JetSpeed rescues to provide more consistent contact. 

As with the R15 line, the AeroBurner, also available Jan. 9, comes with a new matte finish, "pearlized" white paint clubhead. TP options are available for all the metalwoods.

TaylorMade to debut R15 drivers tonight

R15-2.jpg
In the era of the global marketplace, there are no secrets anymore, and news embargoes of product launches seem to be about as effective as leaving a bowl of chocolate-chip cookies in a room full of kindergarteners and asking them to wait.

Hence, it comes as no surprise to anyone that TaylorMade will be unveiling a new driver tonight at a special New York City media event at Golf & Body in Manhattan. The R15, which from all previously published accounts and leaked details from TaylorMade’s Japan website, appears to feature movable weights in the familiar sole track made famous by the company's highly popular SLDR driver, which was launched in 2013. 

R15-1.jpg
The weights appear to slide in a track towards the front of the sole. The SLDR driver emphasized a “low forward” center-of-gravity location aimed at reducing spin and improving the efficiency of energy transfer at impact by placing the center of gravity more in line with both the center of the clubface and the club’s loft. 

Based on the images, the club will be offered in both black and white head styles. TaylorMade first introduced its drivers in white in 2011 with the R11 and RBZ models. It moved off that color in mid-2013 with SLDR, but returned to special limited edition white versions of the SLDR this summer. 

Tom Kroll, TaylorMade product evangelist, described the company's position on white this way last summer: "We still as a company strongly believe in the performance and technology of white and the contrast of a white crown with a black face, and how it aids alignment and the entire aspect that white represents. I think we’re definitely standing behind that. It’s a part of our culture, and people have come to associate TaylorMade with white." 

More details on TaylorMade’s plans with R15 are expected from tonight’s event. Stay tuned.

Cobra's Fly-Z line pushes weight movement and speed

FlyzP1.jpg
Cobra’s new Fly-Z and the Fly-Z+ drivers may not look the same, but both start with the same basic design principle: Saving weight. Both clubs feature a redesigned face structure and hosel from last year’s Bio Cell/Bio Cell+ drivers that combined with a milled indentation around the perimeter of the face saves more than four grams from their predecessors. The Fly-Z+ also incorporates lightweight carbon fiber in the crown and sole to save another 7.5 grams compared to last year’s Bio Cell+. 

fly_z_driver_hero_blue_8bit.jpg
The Fly-Z ($330), which also features a lighter titanium crown design, utilizes the weight savings to produce an oversized, forgiving shape and a high moment of inertia (stability on off-center hits). The saved weight in the Fly-Z+ ($400) makes room for a 15-gram weight chip in the sole that can be positioned toward the front to produce low spin, a flatter trajectory and more roll or toward the back to produce more carry through somewhat more spin. Each model comes in six colors and each features an adjustable hosel with eight loft settings.

The Fly-Z+ is Cobra’s first foray into weight adjustability, and the company’s philosophy is to address the current technology debate in the industry over whether weight should be redistributed to a low and forward center of gravity position or to the more traditional idea of one that’s deeper (farther back from the face). TaylorMade has been the more outspoken advocate of a low and forward setting with its top-selling SLDR driver, while Ping with its equally high-selling G30 has pushed for the higher moment of inertia (stability on off-center hits) design found in many “low and deep” CG positions.

“Many golfers ask why would I need a driver where I could move weight to the front or the back,” says Tom Olsavsky, vice president of research and development at Cobra Puma Golf. “The main reason we want to do this is we want to give you the performance difference that those two weight settings will provide. Some companies say front weight and some companies say back weight. We’re going to give you the choice. We know on tour that some players prefer front settings and some prefer back settings based on the way they swing and what fits their games.”

The line also includes a non-adjustable, offset and draw-biased driver, the Fly-Z XL ($280). It’s available in 9.5, 10.5 and 11.5 lofts. 

All three drivers feature an additional structural element called a “Speed Channel” mirrored throughout the entire line of Fly-Z metalwoods and irons. The emphasis is on building more ballspeed potential through creating extra face flexibility and weight savings. The metalwoods utilize an indent circling the perimeter of the face that reduces face thickness on the front of the club’s extreme outside edges. 

Cobra-1xx.jpg
On the Fly-Z collection of irons (Fly-Z, Fly-Z XL), that same channel moves off the face to an area on the front of the sole and around the perimeter of the cavity. It’s designed to reduce weight that can be redistributed elsewhere, maximize overall face flexibility, as well as minimize sole thickness so that the sole’s flexing can contribute to additional ballspeed. The Fly-Z irons ($800 with hybrids for the 3- and 4-irons) feature an undercut cavity design with a thermoplastic insert fixed in the cavity to control vibration. The Fly-Z XL irons ($500 for eight irons, $600 for the combo set with two hybrids) include a hollow section low in the cavity back on the 4- through 8-irons for higher launch while the shorter irons feature a traditional undercut cavity design. 

The Fly-Z line of clubs will be in stores in January.

Cleveland's latest take on the might of light

CG_BLACK_DRIVER3.jpgAt the elite level, it seems golf is increasingly becoming a power game. That’s all well and good when you have plenty of power to burn. For average golfers, though, power often isn’t so easy to come by. In fact, Cleveland Golf estimates that average golfers, particularly seniors and recreational players, may have swing speeds 15 or more miles per hour slower than the average on the PGA Tour (113 miles per hour).

One solution that’s been offered successfully in Japan for years is clubs with lighter than traditional overall weights. Most notable has been the XXIO brand of drivers launched by Dunlop Sports, which repeatedly have been that country’s top seller, pushing well below 290 grams in total weight. That’s a good 10 percent below the weight of many typical drivers played in the U.S. 

Cleveland, whose parent company is Dunlop Sports, has been developing lighter overall weight golf clubs since the beginning of this decade with clubs like the original CG Black, a driver introduced in 2011 that weighed just 265 grams or about 60 grams lighter than some of the leading drivers in the game at the time. Now comes the new family of CG Black metalwoods and irons, all aimed at average golfers and all featuring an ultralight platform. It’s what Cleveland’s engineers call an emphasis on “increasing the average golfer’s ease of swing.”

Says Jeff Brunski, director of research and development at Cleveland Golf/Srixon, “We looked at the typical average golfer’s swing and ball-flight inefficiencies, and targeted our technologies specifically geared toward them.” 

CG_BLACK_IRON_MONEY1.jpg
The new CG Black driver weighs five grams less than its predecessor, is the lightest driver on the market from a major company and features the concept of lower “swing MOI.” This refers to the moment of inertia of the entire club from head to the butt of the shaft. Instead of a measurement of how stable the club head is on an off-center hit, swing MOI is a theory having to do with how little resistance a particular club might have to being moved. For example, a sledgehammer might have a high swing MOI in that it requires more force to move it faster, but a 260-gram driver like the new CG Black might have a lower swing MOI, making it easier for those less skilled or strong to manipulate it. The concept of swing MOI was also front and center with the recent introduction by Wilson of its adjustable D200 SuperLight driver, which weighs just 268 grams. 

The new CG Black ($350; 9, 10.5 and 12 degrees), which is not adjustable, features the lowest swing MOI of any 460cc driver in company history, and includes a Golf Pride Tour 25 grip that is less than half the weight (25 grams) of a typical rubber grip. 

The CG Black line also includes a sub-300-gram family of fairway woods ($200; 15, 16.5, 18, 20, 23 degrees), which features a 24 percent lighter face that allows the weight to be distributed for higher clubhead stability at a lower total weight. The CG Black hybrids also are about 25 grams lighter than typical hybrids and come in a range of five lofts ($170; 17, 19, 21, 23 and 25 degrees). 

Rounding out the new CG Black line is a mixed set of irons ($700) that includes hollow hybrid-like long irons with 1770 high-strength steel faces, two-piece middle irons with a high-strength steel face insert and traditional one-piece cavity back short irons. It features a center of gravity slightly farther back and lower than last year’s super game-improvement 588 Altitude irons.  

The full line of CG Black clubs is scheduled to arrive in stores next week.

Nike's Vapor drivers move in new direction

Vapor_Flex_Driver1.jpgThe adjustable driver is not new. It’s been around in the mass marketplace for the better part of a decade. While the vast majority recently have focused on changing loft, face and lie angles through rotating hosels, the cool trend from the beginning has been about repositioning center of gravity. 

There have been movable and sliding weights that shifted the CG horizontally toward the heel or toe to produce shots that, respectively, tone down a slice or calm a hook. There even have been drivers that independently from other settings can adjust the vertical center of gravity from high to low, an effort to either better match a player’s specific impact position or effectively let a player choose between low spin or mid-spin.

Now, Nike is offering the option to control CG location in a front-to-back dimension. It's an idea we've seen in some sense with the first TaylorMade r7 driver where the heavier movable weights could be put in the forward position or the rearward position, and most recently with Mizuno's JPX 850 driver that was put in play earlier this year by Luke Donald. The new Vapor Flex driver ($500, available Jan. 30) features a weight cylinder housed flush with the sole that can be flipped so the heavier end is toward the face or toward the back of the driver. The weighting change lets a golfer alter launch angle and spin rate independent of the driver's other loft and face angle settings.

“Often in the fitting process, there’s an opportunity for a final adjustment to develop the shot shape and ball flight the athlete is looking for,” said Nate Radcliffe, Nike’s director of engineering. “As the last step in the fitting process, that can be the difference between the athlete being comfortable with the fitting and really being able to compete with it on the golf course.”

According to Radcliffe, there’s about a two-millimeter difference in the CG location front to back. He says the change from front to back can increase launch angle by a degree, while the change from back to front can reduce spin by 300 rpm. The CG movement also affects the clubhead’s moment of inertia, which is a measurement of its resistance to twisting on off-center hits. On the Vapor Flex, this means the back CG position has about a 300-point higher MOI. Theoretically, some better players may prefer a club with slightly lower MOI, since off-center hits are not as large a concern and because they might find it easier to manipulate the clubhead.

Radcliffe says the weight cylinder system is made possible by the use of the company’s lightweight RZN polymer resin material found in its golf balls and also in the new Vapor irons. “The power of RZN is that it allows us to remove and relocate mass within a club head.” said Radcliffe.

The Vapor Flex (left) is built on the same technology platform as Nike’s Vapor Pro driver that Rory McIlroy recently put in play, as well as the Vapor Speed driver (below right, $300, available Jan. 30), which was also launched today. All three new Nike drivers include a redesigned sole cavity found previously in the Nike Covert and Covert 2.0 drivers. Radcliffe said the redesign included lowering and stiffening the back portion of the cavity to concentrate the flexing toward the front of the crown to improve ballspeeds.

Like the Vapor Pro, Vapor Flex also features the return of a sole channel toward the front of the club to improve the way the face flexes, particularly on low impacts. The channel, which was first part of Nike’s VR drivers in 2010, has been completely redesigned, including some 37 iterations before a final version was settled on. It’s designed to vary in flexibility (it's shallower in the center and deeper towards the heel and toe) to improve the way the face flexes on both on-and off-center impacts.
 
"This is a completely new channel," said Radcliffe. "It does not have a uniform depth."

The drivers also feature a rotating hosel adapter that allows players to independently adjust face angle and loft. The head adjusts between 8.5 and 12.5 degrees with one of three face angles for a total of 15 unique settings. The new hosel is 30 percent lighter than previous versions.

The Vapor Speed features a larger footprint and a slightly higher moment of inertia than McIlroy’s previously debuted Vapor Pro. The crown also slopes down more from front to back compared to last year’s Covert 2.0 to yield a larger face area.
