Srixon ZX-I Series Irons Review: ZX-I7, ZX-I5, and ZX-I4 Compared

Srixon has refreshed its iron lineup with the new ZX-i series, featuring the ZX-i7, ZX-i5, and ZX-i4. These three models cater to a range of players while offering premium feel, refined looks, and advanced performance. But are they really an upgrade over the previous generation? And what’s the deal with the new “i” in their names? Let’s break it down.

What Mark Says...

“The new ZX-i lineup from Srixon is genuinely impressive. They all feel incredible, especially with the new I-Forged process. Whether you're a feel-focused purist, a mid-handicapper looking for forgiveness, or someone like me who just wants help in a sleek package, the ZX-i series delivers. Personally, I’m sticking with the ZX-i4s.”

Inside the Review: A Step-by-Step Breakdown:

1. Meet the Lineup: ZX-i7, ZX-i5, ZX-i4

ZX-i7: Classic player’s iron with compact shaping, minimal offset, and premium forged feel. Ideal for low handicappers and feel junkies.
ZX-i5: Blends player-like looks with added forgiveness. Perfect crossover option for mid to low handicaps.
ZX-i4: A hollow-bodied game improvement iron that delivers distance and forgiveness without sacrificing looks.

Each iron now features the “i”; short for i-Forged, Srixon’s new forging process aimed at enhancing durability and soft feel.

2. Feel, Looks, and Sound

All three models deliver exceptionally soft, forged feels. The ZX-i7 is the softest and most traditional, while the ZX-i4 is now more solid than previous versions.
ZX-i4 previously had a “clippy” sound whereas now it feels more in line with the 5 and 7.
Visually, the differences are subtle: the 5 and 7 look nearly identical at address; the 4 has a slightly larger head but still retains sleek lines.

3. Blending the Set

Blending between models is highly encouraged.
- For example: ZX-i7 from 8–PW, ZX-i5 for 6–7, and ZX-i4 for 4–5 irons.
Just be mindful of loft differences if mixing—custom fitting is key to gapping properly.

4. Shared Technologies

I-Forged Process: Creates softer, longer-lasting forged heads.
V-Sole: Enhances turf interaction.
MainFrame Face: Variable thickness design for consistent ball speeds across the face.
Construction transitions from forged muscle backs to hollow-body long irons for optimal help where you need it.

5. Performance & Numbers

ZX-i4: Longest carry (6-iron average ~202 yards), lower spin due to stronger lofts. Ideal for players who prioritise distance and forgiveness.
ZX-i5 & ZX-i7: Nearly identical in distance/spin, with the 5 offering slightly more forgiveness and stronger flight.
Despite subtle differences, both the 5 and 7 can suit a wide variety of players depending on preference for feel and shaping.

6. Pricing & Value

These are premium-priced irons, comparable to other top-tier forged sets.
Expect ~$1200+ per set, depending on shaft choice and regional pricing.
Add in fitting costs if you plan to blend sets, but worth it for the performance.

Final Thoughts

Srixon continues to make some of the most underrated forged irons in the game, and the new ZX-i series is no exception. The i-Forged update refines feel and durability across the lineup. Whether you're looking for traditional forged feedback (ZX-i7), a forgiving player’s iron (ZX-i5), or game-improvement power (ZX-i4), there's a head for you, and they blend beautifully.

Mark’s Pick: ZX-i4 – More solid feel than before, great distance, and player-inspired looks.

Best for Most Golfers: ZX-i5 – Strikes a perfect balance of forgiveness, feel, and classic shaping.

Best for Purists: ZX-i7 – Soft, precise, and just stunning to look at.
