2021 Srixon ZX4 irons: The final piece of the ZX puzzle
When it comes to building the perfect set of irons, there are endless options, and to help golfers get the most from their iron games, Srixon is completing its ZX iron series with the introduction of the all-new hollow-body ZX4 for 2021.

Considering the recent success of the already popular ZX7 and ZX5 irons, which were released a few short months ago, and the growing popularity of Srixon irons on tour and with consumers, the addition of a fast hollow-body iron makes a lot of sense, given Srixon’s ability to create fast, forgiving, and beautiful looking clubs packed with technology.
“The new Srixon ZX4 irons mark a new revolution in forgiveness for Srixon. The irons include a fully hollow construction with wide soles for getting the center of gravity extremely low and providing maximum forgiveness from the turf.
The ZX4 irons accomplish this in addition to Mainframe technology, Tour V.T.Soles, tungsten weighting, and the look and feel expected with Srixon ZX irons.”
-Dustin Brekke, Director of Engineering at Srixon.

2021 Srixon ZX4 irons: Technology

The ZX4 irons share the same face technology as the ZX5 and ZX Utility known as “MainFrame.” This MainFrame face creates a unique thickness optimization for each iron in the set based on tested strike patterns and was refined using machine learning AKA AI. These varying thickness patterns are all individually milled into the rear of each face (made up of grooves and cavities) to expand the COR.

The face itself is made from forged HT1770 maraging steel and attached to a 431 steel body for great ball speeds and soft feel. Inside of the 431 stainless steel body of ZX4 mid and long irons is high-density tungsten in the sole to lower the center of gravity, boost forgiveness, and help promote high-launching shots.

The other key design feature that sets the ZX4 apart from other irons in the hollow-body category is Srixon’s Tour VT sole to improve the performance through the turf compared to an iron of similar sole width.

Over the years, the VT Sole has gone through some changes, which resulted in softer lines and smoother edges.
In the new ZX series, Srixon returns to its roots with a move aggressively angular VT sole, including well-defined heel and toe notches for improved turf interaction.

Just because the ZX4’s are designed to be game improvement doesn’t mean they can’t offer “players iron-like control.” They achieve this with progressive grooves through the set. The 8-iron through pitching wedge have sharper, narrower, and deeper grooves to channel moisture and debris away more efficiently to generate more spin and shot-stopping control on approach shots.

When compared to the rest of the new Srixon iron series—which includes the ZX7 and ZX5—the ZX4 fits nicely between the ZX5 and utility and offers an extremely clean look from address. Not only that, but the blade lengths have all been configured so golfers that plan to use the ZX4 to build combo sets will see a smooth transition from one iron to the next and even into the new utility.
Price, specs, and availability
The ZX4 irons will retail for $1,299.99 (for an 8 piece set) in steel and $1,399.99 (for an 8 piece set) in graphite.
- The stock steel shaft is the Nippon NS Pro 950GH Neo.
- The stock graphite option is the UST Recoil 760/780.

The Srixon ZX4 will be available for pre-order starting February 22 and will be on retail shelves on March 5.

TaylorMade MySpider Tour and Tour X: More customizable build options now available
TaylorMade Golf’s MySpider program underwent a substantial overhaul over the last month. Firstly, the company launched the option to customize the Spider ZT model, and now the program has returned with the MySpider Tour and MySpider Tour X.
The revamped page now gives golfers complete control over every visual and functional detail of their putter on the popular Tour and Tour X head, with every cosmetic idea thought of. In MySpider Tour, golfers can choose from four head finishes, 16 paint fill colors, nine Surlyn face insert colors, three aluminum insert options, six sightline configurations, and four hosel options — L-neck, small slant, double bend, center shaft. Six sightline options are available in MySpider Tour, including the optically engineered True Path alignment system. MySpider Tour X gives builders the option of four head finishes, four hosel configurations, and five sightline options, also including True Path alignment.
One of the more interesting features of the new MySpider program is the availability of three distinct face insert options. Along with the usual Surlyn Pure Roll insert trusted by Scottie Scheffler and Rory McIlroy, which can be customized from nine colors, golfers can now also select firmer options. Two are offered with the black aluminum Pure Roll insert, slightly firmer than the traditional insert, or for the firmest feel, golfers can choose from two colors of milled aluminum inserts.

Another fun addition to the MySpider Tour is the ability to use the “Tommy Sightline.” The custom alignment aid design, which was first drawn onto Tommy Fleetwood’s putter by PGA Tour Rep James Holley, is based on the milled sightline on his Spider ZT head. There are five shorter lines on the left and right of a longer central line serving as the traditional short line alignment aid.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)

McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X

The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.

The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0

The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)

Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X

Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

Come on doubters — there’s a reason for variable gaps. Engineers with months of testing to come up with a complete set have 10,000% more cred than the unseeing and unbelieving.

i’m turned off by the lofts. first thing i do is look at the pw. if its anything less than 45 the irons are out in my book.

These are cool but 2-degree and 2.5-degree gaps in the long irons is practically useless for most people. Especially amateurs, they probably need at least 3.5-4 degree gaps in the long irons. Even lots of pros have 3-4-degree gaps in the long irons.

lol what is “player’s iron like control” on a 28* 7-iron? I’d be trying to control that thing on its way to the Moon.

Next year these irons will have MCT or Moon Control Technology.
