Srixon ZXi 2027 Irons: Which Model Is Right For You?

The first generation of Srixon’s ZXi irons found favour with professionals and amateurs alike. Now, in September 2026, Srixon is releasing the second generation ZXi range. The ZXi7, ZXi5, and ZXiU all return, with the addition of a new model, the ZXi5+.

We’ll look at what has changed and where the new ZXi5+ fits into the range. But choosing the right Srixon ZXi iron is about more than matching one model to your ability. Depending on factors that are uncovered during a fitting session, the best solution may be a combination of ZXi models built into one set.

What's new in the 2027 Srixon ZXi irons?

The 2027 models can be described as an evolution as opposed to a revolution of the previous generation. A major headline for the ZXi range is that each model is forged at one of the leading Japanese forging houses: Endo. 

If you aren’t familiar with Endo, the short history is that Tiger Woods and Phil Mickelson are two of the highest-profile players to use Endo-forged irons. Why would players of that calibre use Endo-forged irons? Because of the exceptional feel and feedback they provide. Now, you have access to the same master craftsmen through the entire ZXi lineup.

The  ZXi iron range also features Srixon’s i-FORGED process. Refreshed for the 2027 models, i-FORGED is a condensed forging process that strengthens areas of high stress, adding durability while retaining feel and feedback. 

PureFrame iQ has been updated for the new ZXi7 irons. It features a wider and thicker ridge constructed of soft S15C steel and placed directly behind the sweet spot. Srixon’s engineers employed AI to optimise the shape and mass of the ridge to stiffen the impact area, making the face more stable and less prone to twisting.

MainFrame iQ is about maximising the energy transfer from the clubface to the ball at impact. It achieves this through milled channels, grooves, and variable thickness in the back of the face, which are designed to flex in unison at the moment of impact. Srixon has again used AI to simulate thousands of different impact conditions, refining the design while saving weight that can be repositioned to improve clubhead stability.

The Tour V.T. sole is designed to improve turf interaction regardless of whether your ball is on the fairway, rough, or bunker. Srixon has optimised the sole geometry, bounce, and grind to ensure that even if you catch it marginally fat, minimal clubhead speed will be lost. 

Lastly, Srixon’s progressive groove system sees wider grooves in the three iron to seven iron before switching to deeper, closer-set grooves from eight iron down to approach wedge. In all irons, laser milling of the surface between the grooves helps to create consistent spin and control regardless of the course and weather conditions you play in.  

Srixon has also refined the shaping across the 2027 ZXi range, with cleaner transitions and slightly thinner toplines than the previous generation. The changes are designed to give each model a more consistent players-style appearance, particularly when different ZXi heads are combined within the same set.

The Four ZXi Models At A Glance

Srixon ZXi7 - The Players' Iron

The ZXi7 is squarely aimed at the accomplished player who wants to be able to manipulate trajectory and shot shape. The ZXi7s lend themselves well to this type of player due to their thin top line and minimal offset, which is what the better player looks for in the shape of their irons. Golfers who need more help with launch or forgiveness on off-centre strikes will probably be better served by the ZXi5 or ZXi5+.

Srixon ZXi5 - Players' Distance, Blended.

The ZXi5 is going to find its way into the widest variety of players’ bags. The ZXi5 has that classic blend of technology and performance wrapped up in streamlined looks at address but with a moderate amount of offset. Whether used as a standalone set or working as part of a combo set, the ZXi5 offers playability with forgiveness.

Srixon ZXi5+ - The All-New Players' Distance Iron.

The new model in the 2027 lineup, the ZXi5+ combines wider soles, stronger lofts and a longer blade length. The ZXi5+ is a player’s distance iron that promises longer and higher shots, while retaining a strong family resemblance to the rest of the ZXi range. The ZXi5+ will favour golfers who need more help in hitting more consistent and longer iron shots but like the looks of a better player’s iron.

Srixon ZXiU - The Utility / Driving Iron

Designed to fit into the two-, three-, and four-iron equivalent, and an alternative to the equivalent hybrid or lofted fairway wood, the ZXiU boasts the same good-looking head profile behind the ball as the rest of the ZXi series. The ZXiU is designed to get the ball launching and spinning more easily than the long iron counterpart, which makes it a worthy contender to be in the bag of competent ball strikers.

Which Srixon ZXi Iron Is Right For Me?

A question we often get asked during iron fitting sessions at Nine By Nine Golf. 

The 2027 ZXi range offers something for every level of golfer, but understanding what model, or models, work best for your game lies in the value of a fitting session.

The reason we say this is simple. Analysing ball data and strike patterns helps to quantify what’s best for your game.

At the outset, we need to understand where your iron play sits by assessing your existing set. What we are looking for is to understand how consistent a ball striker you are. When you miss the sweet spot, do you have a consistent miss in the toe or heel of the iron? We’ll also look at your launch and spin numbers, and what your overall shot dispersion looks like.

If you are an inconsistent ball striker, the chances are the ZXi5+ could be a good fit with its longer blade length and focus towards forgiveness. If you need help in launching and spinning the ball more effectively with the longer clubs, the ZXiU could be the route to go or maybe the ZXi5+.

Mid- to lower handicap golfers who want a bit more playability but still want the safety net of some forgiveness could be fitted for the ZXi5 irons.

The intriguing thing is that you don’t have to opt for one model; the best iron set option could lie in a combo set. Combo sets blend together different models to maximise the overall performance of an iron set. A player might need more help in the longer irons but get the best out of precision-focused shorter irons. Looking at the 2027 Srixon ZXi irons, this could mean a mix of ZXiU and ZXi5 or ZXi7 irons.

Choosing the right models, and where to make the switch between them, comes down to the launch monitor data.

The key considerations are creating consistent distance gapping, launch and spin numbers throughout the set, and that’s where your fitter will be focused.

There is no hard-and-fast rule that a combo set is made up of two different models. We could easily fit a player for ZXiU long irons, ZXi5 mid irons, and ZXi7 in the short irons; it purely depends on what gives the best numbers. 

The beauty of the 2027 Srixon ZXi iron family is that there is a synergy across the looks of each model, which gives a level of consistency from one iron to the next. But creating the correct combo set doesn’t just come down to which model of head is selected.

Why Buy Your ZXi Irons Custom-Built And Fitted

Custom-fitting is about building each club to the exact specification required for each golfer. Choosing the right head, or combination of heads in a combo set, is only one part of building the correct set for the golfer. The next element is analysing what the correct shaft is for each player’s requirements.

We all have different clubhead speeds and load and unload the shaft in ways that are unique to our swings. Therefore, in order to match the correct shaft, the fitter will consider which shaft weight and material is best suited to each player’s swing characteristics.

Nine By Nine also offers an extensive range of steel and graphite shaft options, allowing the fitter to look beyond the standard offering when the player's swing requires it.

Adding distance is an obvious benefit of playing the right shaft, but the correct shaft can also improve ball striking and shot dispersion, two crucial elements of good iron play.

Not every golfer we fit clubs for is the same height, so we need to make sure that the finished recommendation ensures the clubs are built to the right length and lie angle.

Having the correct length and lie are also vital elements of gaining more consistency. Clubs fitted to the correct length mean that no compromises are made at address and then in the swing because the golf club is too short or too long. Correct lie angle can also aid ball striking and shot dispersion.

It’s easy to think that grip selection might simply be a case of choosing the one that has the best colours, but there is more to it than that. The grip forms our only contact with the club, so it has to feel comfortable. 

Every player has a different hand size so our fitters will also make a point of establishing if additional layers of tape should be applied to accommodate bigger hands. Midsize and jumbo grips can also be considered as alternative options, with the selection coming down to what feels comfortable for the player.

Why do we need to pay such close attention to grip selection? Playing grips that are too thin or too thick can affect clubface control in the swing, leading to wayward shots; not conducive to good iron play.

That level of detail is carried into the build of the clubs with our in-house team at Nine By Nine Golf, who use the same tour-standard equipment and measuring to build each club to the exact agreed specifications.
