Srixon ZXi irons now on sale: what i-FORGED and MainFrame iQ really do
The new ZXi line reached retailers October 16. We examine four models, Japanese forging, the lighter face structure and fitting trade-offs.
Srixon's second-generation ZXi irons went on sale on October 16, 2026. They were officially announced on September 8, meaning October marks retail availability rather than a fresh unveiling. The family consists of ZXi7, ZXi5, the genuinely new ZXi5+ and ZXiU.
Why forging matters
The i-FORGED process combines Condensed Forging with controlled localised heat treatment. Srixon aims to reinforce high-stress material around the face grooves while retaining softer properties elsewhere in the head. All heads are forged by Endo Manufacturing in Japan. The manufacturer describes improved durability and impact feel, although its launch announcement contains no independent long-term wear comparison to quantify those gains.
The role of AI-assisted engineering
The ZXi5, ZXi5+ and ZXiU use MainFrame iQ, developed after simulations of thousands of impact locations. Srixon says engineers reduced face mass by up to 8% and shifted the saved weight to improve stability on off-centre hits. Importantly, 8% describes face-mass reduction, not a promised 8% increase in ball speed or distance. The compact ZXi7 instead uses PureFrame iQ, an optimised forged ridge behind the sweet spot designed to control stiffness and feedback.
Four different choices
ZXi7 targets shot shaping and precise trajectory control, using S15C steel, tungsten and compact shaping. ZXi5 blends forged feel with more stability. The new ZXi5+ is a fully forged hollow-body players-distance iron with stronger lofts, a longer blade and a wider sole. ZXiU is intended as a versatile alternative to a conventional long iron.
Srixon's Tour V.T. Sole combines model-specific sole widths, bounce angles and notches intended to influence turf interaction. Results depend on a golfer's angle of attack and course conditions. The range is also shaped and weighted to support mixed-model iron sets.
Prices and what a fitting should reveal
In the US, seven-club steel-shaft sets of ZXi7, ZXi5 and ZXi5+ are $1,499.99 at launch. ZXi5 and ZXi5+ graphite sets cost $1,599.99; a single ZXiU costs $259.99. Pricing varies by market.
A stronger loft is not automatically better. Compare launch angle, peak height, spin, landing angle, dispersion, distance gaps and mishit results. One exceptionally long centred strike matters less than repeatable on-course performance. These technological advantages are manufacturer claims, not our independent head-to-head test.
