Srixon ZXi5 + ZXi7 combo set: the stock split is at the 7-iron, and 9 of the 10 ZXi7 tour bags we track switch sooner

Ten of the 80 tour bags we track carry Srixon ZXi7 irons, and all ten have ZXi5 irons sitting above them. Srixon has now turned that habit into a product. The Srixon ZXi5 + ZXi7 Combo Set went on sale with the second-generation ZXi irons on 16 October at $1,500 for seven clubs, and the one thing worth knowing before you order it is where the join sits. Srixon's stock set switches at the 7-iron. Only one of those ten tour bags does.

What is in the box

Srixon's product page lists the stock build as ZXi5 from the 4-iron to the 6-iron and ZXi7 from the 7-iron to the pitching wedge, on True Temper Dynamic Gold Mid 115 shafts in stiff with Golf Pride Tour Velvet 360 grips. It says other splits can be configured as custom orders. The page shows the set as available to order with an estimated ship date of 30 October, so this is a pre-shipping product for another few days, not a shelf item.

The two heads are different clubs built on one platform. Both are forged by Endo in Japan, which The First Call's report of the 8 September launch confirmed for every second-generation ZXi iron. The ZXi5 uses an S20C steel body with what Srixon calls MainFrame iQ, a milled pattern of grooves and channels on the back of the face designed for ball speed. The ZXi7 uses S15C steel and PureFrame iQ, a thicker forged ridge behind the sweet spot that Srixon says stiffens the impact zone and frees up mass for stability. Long and mid irons in both models carry a tungsten toe weight. Srixon's own comparison chart rates the ZXi7 for low handicaps with low-to-mid forgiveness and the ZXi5 for low-to-mid handicaps with mid forgiveness.

The money is the part that surprised me. Seven ZXi7 irons cost $1,500 on Srixon's US store, and so do seven ZXi5 irons in steel. The combo costs the same. You are not paying extra for the blend, and you are not getting a discount for it either.

The number: 10 tour bags, 3 different joins

10 of the 80 tour bags we track carry ZXi7 irons, and every one of the 10 also carries ZXi5. There are 11 ZXi5 bags in total; the extra one is Hideki Matsuyama, whose ZXi5 is a single 3-iron with no ZXi7 below it. By tour, the ten are six on the PGA Tour, three on the LPGA and one on LIV.

Where they switch from ZXi5 to ZXi7 is the useful part:

- At the 6-iron: 6 bags. Shane Lowry, Sepp Straka, Keegan Bradley, Ryan Fox and Nico Echavarría on the PGA Tour, and Lilia Vu on the LPGA. Vu also carries a ZXi4 4-iron, so hers is a three-model set. - At the 5-iron: 3 bags. J.J. Spaun, Hannah Green and Lucas Herbert. Herbert's ZXi7 is a single 5-iron, and he moves to Miura from the 6. - At the 7-iron: 1 bag. Miyu Yamashita, who carries one ZXi5, a 6-iron, above ZXi7 from the 7.

So nine of the ten switch earlier than Srixon's stock set, and the one that matches it carries a single ZXi5 rather than three.

How we counted, so you can check it: we searched every bag in our file for a ZXi7 and a ZXi5 row, printed the rows and counted one per player, because rows are not bags. The eight creator and amateur bags are left out, and none of them carries a ZXi7 anyway. These are the bags we maintain and re-verify against named sources, not a census of any tour, and most were last verified between July and mid-September. That means most of these heads are first generation. The split is a decision about the set, not about the generation, and Fox is the bridge between the two: Srixon's launch release credits his Open win in July to the new irons, and his set switches at the 6.

Why the tour switches sooner

Read Srixon's own chart and the reason is plain. The ZXi7 is the low-handicap head and the ZXi5 is the one with more help. A tour player wants the compact head, the thinner topline and the control for as many clubs as they can strike it, and gives up only the longest irons, where a bit of extra ball speed and launch earns its keep. For most of these players that line falls at the 6. Spaun, Green and Herbert push it one club further. The stock set is drawn for the golfer one step down from that, who wants the ZXi5's help through the 6-iron as well.

There is also a small gapping wrinkle in the stock join, and it comes straight off Srixon's spec tables. The ZXi5 runs a degree stronger than the ZXi7 in the long irons: its 5-iron is 24 degrees against the ZXi7's 25, and its 6-iron 27 against 28. Both models have a 32-degree 7-iron. So the combo's step from the 6-iron to the 7-iron is five degrees, where a straight ZXi7 set steps four, from 28 to 32, and the combo's own next step, 7 to 8, is four again. It is one degree, not a disaster, but if your 6-iron and 7-iron already fly too far apart, ask a fitter about a one-degree loft tweak or a different split. Srixon's order page offers both.

Second generation, or the first one cheaper?

The first-generation Srixon ZXi7 has not gone away. Srixon's own store now sells it as the ZXi7 Irons (2025) at about $1,400 for seven clubs, roughly $100 under the new set, and it is still in stock. We explained the trap of a brand reusing the same model name in our piece on same-name generations, and this is a live case of it: two different ZXi7 irons, one name, on the same website.

The case for the new one is modest. Golfalot's review of the 2026 ZXi7 found it a refinement of the original, with a modest improvement in looks and feel, and said it would not rush to upgrade from the first generation. That matches what Srixon is claiming: an AI-assisted update to the ridge behind the face and thinner toplines, not a new head. If you already play a gen-one ZXi7 or a ZXi5/ZXi7 blend, there is very little here for you. If you are buying new, the price gap is small enough that the newer head is the one I'd take.

Who should buy it, and who should skip it

Buy it if you are a single-figure player who wants a players' iron in the scoring clubs and some help at the top, and your 6-iron is a club you hit with a bit less confidence than your 7. That is exactly the golfer the stock join is drawn for, and seven matched heads on one order is simpler than building the set yourself.

Order a custom split instead if you strike your 6-iron as well as your 8. That is what six of these ten tour bags did, and Srixon will build ZXi7 from the 6 at no extra cost. If you are comparing forged players' irons more broadly, our Titleist T100 vs Srixon ZXi7 comparison covers the main alternative.

Skip it if you are a mid-handicapper looking for distance. Srixon's own chart puts the ZXi5+ and ZXiR in that lane, and a set with four ZXi7 heads in it is not built for you. Skip it too if you own a first-generation blend already. The change is real but small, and our irons and wedges guide has the wider field.
