Stock lofts compared

Each cell lists the heads sold at that stock loft, factory standard. Adjustable hosels extend every head beyond its stamped loft — each model page has the full settings chart.

What the differences mean

Both families are sold in 1 head — Std for the ST-MAX 230, Std for the JPX One.

Stock loft coverage is identical: both run 19° to 28° across the same 4 stock lofts.

Adjustability is a wash: both use the same hosel system (Quick Switch, ±2° of loft), so a given head reaches the same effective loft window in either generation.

The JPX One arrived 2 years after the ST-MAX 230 as its replacement. Hybrid generations usually carry over the loft ladder and move the technology — face design, adjustability, head options — so the older family is the value buy on the used market while the newer one holds retail price.

Which should you choose?

The JPX One is the newer generation, so it carries the current face technology and full retail availability; the ST-MAX 230 is the value buy used or on closeout. If the head and loft you want is only in one lineup, that decides it — otherwise the newer family is the default at equal prices, and the older one the smarter buy at a real discount.

Both families are charted in full on their own pages: Mizuno ST-MAX 230 hybrid specs and Mizuno JPX One hybrid specs.
