Callaway Steelhead XR irons and hybrids

Callaway’s new Steelhead XR irons and hybrids each draw from equipment designs and technologies in the company’s history.
The new Steelhead XR irons are influenced by the Steelhead X-14 irons — some of the most highly coveted irons in Callaway’s catalog — that were released in the year 2000 (click for a reminder of what they look like). For its new release of game-improvement irons, Callaway looked to the classic Steelhead X-14 irons for shaping and mass properties, and used its since-acquired knowledge of iron design to add performance benefits.
The Steelhead XR hybrids also implement designs from other Callaway products, albeit from the not-so-distant past. For its Steelhead XR hybrids, which are to be used as replacements or complements to the iron set, Callaway borrowed design concepts from both the Apex hybrids — originally designed for better players, according to Callaway — and the Callaway XR drivers, which were co-engineered with Boeing.
For more specifics, read below. To join the conversation about the Steelhead XR release and see more photos, CLICK HERE.
Callaway Steelhead XR irons
Callaway’s line of XR clubs have become known for speed and forgiveness. The new releases are no different in that sense.
The idea behind looking into its history at the Steelhead X-14 irons was to implement characteristics of shaping and mass properties to make a more forgiving, balanced iron. Visibly, you’ll notice a “hitch in the topline near the heel,” as Dr. Alan Hocknell, Callaway’s Senior VP of R&D, describes it. This allowed Callaway to put the center of gravity (CG) at the direct center of the club head, in relation to the heel and toe. Additionally, there is a bore-through in the heel, helping also to control the CG, and to raise moment of inertia (MOI), according to Hocknell.
It was important for Callaway to control CG from heel-to-toe, placing it on the center line, as well as controlling it from top to bottom. The irons are designed to have lower CG in the long irons, where higher launch is crucial for more distance, forgiveness and stopping power. On the other hand, the short irons are designed with higher CG, which is important for control, and to avoid producing shots that are “too floaty,” as Hocknell said.
Callaway uses a new material — steel-infused polyurethane — that sits behind the face in the cavity of the irons, which are made from 17-4 stainless steel. The material (pictured above) is placed low in the irons to drive CG downward, and also serves to dampen vibrations at impact, keeping the irons from feeling harsh, according to Callaway.
The Steelhead XR irons were also designed with coefficient of restitution (COR) that goes “as high as anybody dares to go,” Hocknell said. With faster 360 Face Cups — Callaway’s familiar variable-thickness faces that are welded to the bodies — than previous irons, the Steelhead XR irons have thinner perimeters helping to extend the high-COR area, and pushing it right up to the legal limit. This means they will produce extremely fast ball speeds across the face.
Steelhead XR iron sets (3-LW) will be available in stores on September 2, and will sell for $799 with a steel shaft and $999 for graphite. Stock shafts will be True Temper’s XP 95 Stepless (Steel) and Matrix’s F15 (Graphite), although there is a “wide array” of aftermarket shafts available.

Steelhead XR hybrids
To Callaway’s surprise, according to Hocknell, average players showed serious interest in the recently released Apex hybrids, although they were designed for lower-handicaps.
After listening to the feedback, Callaway looked to the Apex design, and made some adjustments for those who need more forgiveness, launch, and ultimately, distance. To do this, Callaway made the blade lengths longer, and made the club heads deeper from front-to-back, while keeping the familiar squared-off toe reminiscent of the Apex hybrids. The bigger surface area of the face allowed the Steelhead XR hybrids to have higher MOI than you’ll find from the Apex hybrids, but a similar head shape.
Also, you’ll notice the Steelhead XR hybrids have Callaway’s Hyper Speed Face Cups welded to the bodies, which are made to enhance ball speeds on mishits.
For additional head speed, Callaway implemented the familiar Speed Steps from Callaway’s XR drivers, engineered in tandem with Boeing, that are said to provide better aerodynamics for players who need it.
The Steelhead XR hybrids (3-6) will be available in stores on September 2, selling for $219 each. Matching the irons, they too will have True Temper’s XP 95 (Steel) and Matrix’s F15 (Graphite) stock shafts, although there is a “large selection” of aftermarket shafts available.

Next “Ping Slam” putter announced: Ping PLD Limited Zing 2

Following the Pal and Pal 2, Ping today announced the release of the third of four “Ping Slam” putters, which commemorate the 1988 season in which the brand won all four men’s major championships.
The precision-milled PLD Limited Zing 2 putter commemorates Curtis Strange’s 1988 U.S. Open win — the first of his two consecutive U.S. Open wins using the putter.
“We’re really enjoying celebrating the ‘Ping Slam’ and reliving some wonderful memories from 1988,” said John A. Solheim, Ping’s Executive Chairman. “Curtis’ thrilling win at the U.S. Open was soon followed by the U.S. Women’s Open champion using a Zing 2, giving us wins at both national championships that summer. The next year Curtis won the U.S. Open again with his Zing 2. That was a remarkable run for the Zing 2 and secured its place in Ping’s putter history.”
Arriving on tour in 1984, the original Zing 2 was inspired by the Zing was cast from stainless steel. Ping cites the heel-shafted design and heel-toe weighting as key elements of the putter’s popularity.
The putters are custom-built by Ping WRX master craftsmen at the company’s headquarters in Phoenix, Arizona. Each putter is serialized for authenticity and includes a custom headcover. Ping’s engineers and company historian scoured the archives to retain the integrity of the four classic designs during the milling process, spending time in the legendary Ping Gold Putter Vault to ensure the integrity of the designs.
Pricing, availability
Only 88 of the 100-percent milled, 303 stainless steel, natural finish putters are available via pingpld.com at 2 pm ET, Tuesday, June 13 at a price of $990.
Later this year (December 5), 35 complete sets of the PLD Limited ‘Ping Slam’ putters will go on sale for $4,990 (limit one per customer), which will include a custom-designed display unit.

No matter what haters complaining, this steelhead irons have really good quality.
I compared with apex cf16 with same stock shaft, xp95. steelhead was softer and more precise. I landed every shot 2 yard radius, I was really impressed.

I personally LOVE these so much. Seriously the greatest club ever designed. I really didn’t think Callaway could come out with anything better than the Apex CF16 but wow have they proven me wrong. I’ll have these in my Callaway stand bag as soon as they hit retail. I don’t even need to see the price tag – just ring them up and take my money.

Not sure what Callaway is doing with their club releases? Now they will have XR, XR Pro, XR OS, Steelhead XR and then the Apex line. Where do these slot in or are they meant as the replacement for the XR series? They’re starting to act like TM on the multiple releases. Very confusing.

Those would be the 2016.2 Steelhead Apex XR OS OMG driver and fairway. The OMG stands for the Oversized, Massive, Gigantic sweet spot just above the aftermarket weight ports that will have a different adapter and and 12 colors to choose from. Unless you’re a Lefty.
