The entire ZXi line is now Endo Forged
The entire line is now fully forged by Endo Manufacturing, a renowned Japanese forger. Previously Srixon had used Endo for some irons, but this is the first time the whole ZXi lineup is produced in full partnership with them.
Lineup Restructuring
The ZXi4 is replaced by the new ZXi5+ — a hollow-bodied players-distance iron with a longer blade, stronger loft, and wider sole than the ZXi5.
The ZXi5 now leans slightly more toward a "player performance" iron (more workability/spin) and
the ZXi7 and ZXiU return, looking similar to before by design.
Technology Tweaks
New MainFrame iQ (ZXi5, ZXi5+, ZXiU) uses AI-assisted design to reallocate mass low behind the face and boost MOI.
New PureFrame iQ (ZXi7) uses AI to stiffen the impact zone, cut unwanted face deformation, and improve stability.
Thinner Topline Across The Board
Thinner toplines across the board and cleaner visual transitions, based on Tour player feedback.
