Here is the checklist for telling them apart, and the case for buying the one being cleared out. ## In short - Srixon announced a second-generation ZXi family on 8 September 2026 that reuses the ZXi7, ZXi5 and ZXiU names, adds a ZXi5+, and reaches retail on 16 October, so the model name alone no longer identifies which generation you are looking at. The reliable tell is the named face technology rather than the model name: PureFrame iQ marks the new ZXi7, while the outgoing generation was sold on MainFrame and PureFrame. Run the rest of the checklist in order — a suffix like the Takomo 101 MKII, an incremented digit like Ping's i230 to i240, a new sibling model in the family, the maker's own product code, and the price. Near-misses are worse than repeats: the Titleist GT2 and GTS2 are one letter apart, and the GT2 was cut by roughly thirty per cent when the GTS2 landed despite having topped a full-field distance test. In an overlap window the outgoing generation on clearance is usually the smarter buy, because the year-on-year gain is small and the discount is not. Buy current if you need a fitting, if you are left-handed, if the construction genuinely changed, or if you want a matched set in one order. On 8 September, Srixon announced a second generation of its ZXi iron family. The new range arrives as a ZXi7, a ZXi5 and a ZXiU, plus a new ZXi5+ players' distance iron. Pre-sale opened on 8 September and the clubs reach retail on 16 October, listed at just under fifteen hundred dollars at US prices for seven steel-shafted clubs. Read that list of names again. Those are the same three names the previous generation already had. This is not a scandal and nobody is hiding anything. It is, though, a specific and avoidable way to spend a four-figure sum on a set of irons that is not the set you thought you were buying, and for the next few months the word ZXi7 on a shelf, a listing or a second-hand advert does not tell you which of two different clubs you are looking at. That is a solvable problem and it takes about ninety seconds. ## The names used to change. That is what makes this new Srixon's own recent history is the clearest illustration of how unstable golf club naming has become, because this one line of irons has run three different conventions in about five years. There was the ZX7, then the [ZX7 Mk II](https://ifrothgolf.com/product/srixon-zx7-mk-ii) — a suffix, on the box, doing exactly the job a suffix exists to do. Then the family was renamed entirely and the [ZXi7](https://ifrothgolf.com/product/srixon-zxi7) appeared, a forged players' iron with a MainFrame face design, a thin topline and modest offset, built to combo with the more forgiving ZXi5 in the long irons. And now a second ZXi7 arrives with no suffix, no bumped digit and no new letter. The [ZXiU](https://ifrothgolf.com/product/srixon-zxiu) utility iron is in the identical position: a hollow-body driving iron under a name that a different hollow-body driving iron will also carry from 16 October. Both of our pages describe the outgoing generation, and both are now flagged as superseded in our own lifecycle records, because the honest thing to tell someone reading about a club is which generation the words in front of them refer to. ## The tell is the technology name, not the model name Here is the practical answer, and it generalises well beyond Srixon. **The named face or internal technology is the reliable identifier.** Model names get recycled. The marketing name a brand gives to a face, a frame or an internal structure almost never does, because the whole point of inventing that name is to make this year's engineering sound new. The second-generation ZXi7 introduces **PureFrame iQ**. The generation before it was sold on MainFrame and PureFrame. If the listing, the box or the shaft label says PureFrame iQ, it is the new one. If it does not mention it at all, assume it is not. That is the first thing to look for on any club where the name alone is ambiguous. The rest of the checklist, in the order I would actually run it: **The suffix.** Mk II, MKII, II, a bracketed year. When a brand uses one, it has done you a favour. The [Takomo 101 MKII](https://ifrothgolf.com/product/takomo-101-mkii-irons) is the tidy version — a direct-to-consumer game-improvement iron that won MyGolfSpy's 2026 Best Game-Improvement Iron award, at around $650 for a seven-piece set, with the generation printed in the name so that a listing cannot be ambiguous even by accident. **The digit.** Ping runs the cleanest system in irons: the number goes up when the club changes. The [i240](https://ifrothgolf.com/product/ping-i240-irons) is the successor to the much-loved i230, and you can tell at a glance, from a thumbnail, in a badly lit second-hand advert. That is not a small thing. It is a naming convention that respects the buyer. **The new sibling.** A family that gains a model has told you which generation it is. The ZXi5+ exists only in the second generation, so a listing that mentions it anywhere on the page is describing the new range even if the specific club is called ZXi7. **The maker's own product code.** Brands are far more disciplined about SKUs than about marketing names, because a warehouse cannot cope with ambiguity. The manufacturer's own product page carries a model code, and comparing that against a retailer's listing settles almost every case the words leave open. **The price.** The outgoing generation is the one that just got cut. That is not a coincidence and it is about to become the most useful line in this piece. ## The near-miss version, which is worse Same-name is at least honest about being the same name. The nastier case is one letter. The [Titleist GT2](https://ifrothgolf.com/product/titleist-gt2-driver) was replaced in June by the GTS2. Read those quickly, in a list of search results, on a phone, and they are the same word. We hit this in our own tooling: a pattern written to match GTS2 cheerfully matched a shaft code that had nothing to do with either club. If a regular expression cannot reliably tell them apart, a golfer scrolling a marketplace at eleven at night has no chance. But look at what happened next, because it is the whole argument. The GT2 topped MyGolfSpy's full-field driver test for outright distance and took a Golf Digest Hot List gold. Then the GTS2 landed and the GT2's price was cut by roughly a third, opening a gap of well over a hundred pounds — and a wider one again in dollars — between two heads separated by a model year. The club did not get worse in June. The badge did. ## So buy the outgoing one, most of the time This is the position, and I will defend it: in the overlap window, the previous generation on clearance is usually the better purchase, and treating it as second best is the mistake. Three reasons. The first is that the year-on-year gain in a mature club category is small and the discount is not. Our own write-up of the GTS2 says the honest quiet part out loud — the gain over the previous season's model is modest, and the win comes from a proper fitting for loft and shaft rather than from the new badge. A thirty per cent cut against a single-digit performance change is not a close call. The second is that the outgoing model has been reviewed properly. It has a year of independent testing, forum threads full of real owners, known shaft pairings and a resale price that has already found its level. A club announced five weeks ago has a press release and some launch-day impressions. The third is gapping and fitting continuity. If you already play the outgoing generation, buying more of it — a utility iron to match a set, a replacement after a bent shaft — keeps lofts and lie angles consistent in a way that mixing generations under one name absolutely does not. This is the case where the naming overlap does real damage: two clubs called ZXiU, bought eighteen months apart, are not guaranteed to be the same club. ## When the new one is genuinely the buy Four situations, and they are not edge cases. If you need a fitting, the current generation is what is in the fitting cart, in every head, every loft and every shaft. Clearance stock is whatever is left, which in practice means standard lofts, a couple of stock shafts and steel before graphite. If you are left-handed, the outgoing generation runs out of your side of the range first and it is not close. If the change is structural rather than cosmetic, pay for it. A new face technology in a players' iron is usually a refinement; a genuinely new construction is not. Read what changed rather than the generation number — the same discipline that applies to [the word forged](https://ifrothgolf.com/read/what-forged-actually-means-irons) and to [the word ironwood](https://ifrothgolf.com/read/what-is-an-ironwood) applies here. The badge is a label. The construction line underneath it is the product. And if you want a full set in one order, in one finish, arriving together, buy current. Chasing a clearance set across three retailers is how people end up with a mismatched 4-iron. ## What to do at the counter Ask one question and it settles everything: *which generation is this, and what is the face technology called?* A shop that knows will answer in four words. A listing that cannot answer it is a listing to walk away from. Then check the maker's product code against the listing, look for the new sibling model anywhere on the page, and note the price against the launch list. If it is heavily discounted, you have almost certainly found the outgoing generation — which, nine times in ten, is the one I would be buying anyway. We put the first-generation ZXi7 up against the [Titleist T100](https://ifrothgolf.com/read/titleist-t100-vs-srixon-zxi7) earlier this year and nothing in the second-generation announcement changes that argument. It just changes what you have to do to be sure which one is in the box. ## The takeaway Srixon announced a second-generation ZXi family on 8 September 2026 that reuses the ZXi7, ZXi5 and ZXiU names, adds a ZXi5+, and reaches retail on 16 October, so the model name alone no longer identifies which generation you are looking at. The reliable tell is the named face technology rather than the model name: PureFrame iQ marks the new ZXi7, while the outgoing generation was sold on MainFrame and PureFrame. Run the rest of the checklist in order — a suffix like the Takomo 101 MKII, an incremented digit like Ping's i230 to i240, a new sibling model in the family, the maker's own product code, and the price. Near-misses are worse than repeats: the Titleist GT2 and GTS2 are one letter apart, and the GT2 was cut by roughly thirty per cent when the GTS2 landed despite having topped a full-field distance test. In an overlap window the outgoing generation on clearance is usually the smarter buy, because the year-on-year gain is small and the discount is not. Buy current if you need a fitting, if you are left-handed, if the construction genuinely changed, or if you want a matched set in one order. ## FAQ ### How do I tell which generation of a golf club I am looking at? Check the named face or internal technology rather than the model name. Brands recycle model names but rarely reuse a technology name, because inventing it is how they sell the new version. On the second-generation Srixon ZXi7 that name is PureFrame iQ; the previous generation was sold on MainFrame and PureFrame. After that, look for a suffix, an incremented number, a new model in the family, the manufacturer's own product code, and a sudden discount. ### Is the new Srixon ZXi7 different from the old ZXi7? Yes. Srixon announced a second-generation ZXi family on 8 September 2026 that keeps the ZXi7, ZXi5 and ZXiU names and adds a new ZXi5+. The second-generation ZXi7 introduces PureFrame iQ. Pre-sale opened on 8 September and the clubs reach retail on 16 October, so for a period both generations will be on sale under the same names. ### Is it a mistake to buy last year's irons on clearance? Usually not. In a mature category the year-on-year performance change is small while the discount often is not, and the outgoing model has a year of independent testing, known shaft pairings and a settled resale value behind it. The Titleist GT2 topped a full-field distance test and won a Hot List gold, then had roughly thirty per cent cut from its price when its successor arrived. ### When should I pay for the current generation instead? When you need a proper fitting, because clearance stock is only what is left rather than the full range of heads, lofts and shafts. When you are left-handed, because those run out first. When the construction genuinely changed rather than the badge. And when you want a complete matched set in one finish delivered together. ## Products mentioned - [Srixon ZXi7](https://ifrothgolf.com/product/srixon-zxi7) · $1,400 approx — The outgoing generation, and the one whose name a second-generation club now shares exactly. **Where to buy:** [Check price at Amazon](https://www.amazon.com/dp/B0DT3CG5GM?tag=ifrothgolf-20&ascsubtag=md_srixon-zxi7) (affiliate link) · also stocked by Srixon - [Srixon ZXiU](https://ifrothgolf.com/product/srixon-zxiu) · $250 approx — The outgoing utility iron, in the same position: a new one arrives in October under the identical name. **Where to buy:** [Check price at Amazon](https://www.amazon.com/dp/B0DT3PDFPQ?tag=ifrothgolf-20&ascsubtag=md_srixon-zxiu) (affiliate link) · also stocked by Srixon - [Srixon ZX7 Mk II](https://ifrothgolf.com/product/srixon-zx7-mk-ii) · $1,400 approx — The generation before that, and the evidence that this brand changed its naming convention twice before landing on one that repeats. **Where to buy:** [Check price at Srixon](https://us.dunlopsports.com/srixon/clubs/irons/zx7-mk-ii-irons/zx7-mk-ii-irons/ZX7MKIIIRN.html) - [Takomo 101 MKII Irons](https://ifrothgolf.com/product/takomo-101-mkii-irons) · $650 approx — How a suffix is supposed to work: the MKII is on the box, so nobody has to guess which one they are holding. **Where to buy:** [Check price at Takomo](https://takomogolf.com/products/iron-101-mkii) - [PING i240 Irons](https://ifrothgolf.com/product/ping-i240-irons) · $1,350 approx — The clearest naming system in irons, because the number goes up when the club changes. **Where to buy:** [Check price at PING](https://ping.com/en-us/clubs/irons/i240) - [Titleist GT2 Driver](https://ifrothgolf.com/product/titleist-gt2-driver) · $450 approx — The near-miss case, one letter away from its own successor, and the best illustration of what happens to the outgoing model's price. **Where to buy:** [Check price at Amazon](https://www.amazon.com/dp/B0DHWNVBK8?tag=ifrothgolf-20&ascsubtag=md_titleist-gt2-driver) (affiliate link) --- Source: [ifrothgolf](https://ifrothgolf.com) — independent golf-gear editorial.
