Identifying the right model

• A chrome utility back with ZXiU lettering on the upper bar, SRIXON low toward the toe, MAINFRAME IQ lettering low toward the heel, a 4 23 marking on the top line toward the toe and a small round dot at the far toe; the hosel reads i-FORGED.

What to check before using the reference

• Srixon lists this ZXiU separately from the ZXiU Utility Irons (2025), which has its own record; this head reads MAINFRAME IQ and lists a 3.6 mm offset and D1 swing weights, the 2025 head reads MAINFRAME with 4.2 mm offset.
• The table lists steel and graphite stock lengths separately (graphite ½ in longer); Length is the steel figure and the graphite length is given alongside.
