Lofts are the stamped stock options for each head, factory standard. The hosel chart below shows how far each can be adjusted from its stamped loft.
Length note: Mizuno publishes lengths to the USGA / R&A measurement method, which reads about a quarter inch longer than its older charts without the builds changing. Lie is published only as a per-loft adjustable range (58.5-61.5° on the 3HB), so no lie column is charted.
Hosel adjustment chart
Quick Switch · loft ±2°.
Each loft adjusts across a 4° window (the 19° 3HB plays 17-21°), with lie moving within a 3° band as loft changes. Mizuno publishes the ranges but no position-by-position chart for the Quick Switch, so no settings table is reproduced here.

About the Mizuno ST-MAX 230
The ST-MAX 230 hybrids launched in early 2024 with the ST-MAX 230 woods — one high-MOI head in four lofts from a 19° 3-hybrid to a 28° 6-hybrid, each carrying Mizuno's Quick Switch adjustable hosel with a 4° window. Head sizes run 122 cc down to 109 cc. The JPX One hybrids replaced the line in 2026.

Frequently asked questions
What lofts does the Mizuno ST-MAX 230 hybrid come in?
Four lofts: 19, 22, 25 and 28 degrees. The 19 and 28 degree heads are right-hand only.
Is the Mizuno ST-MAX 230 hybrid adjustable?
Yes — every loft uses Mizuno's Quick Switch hosel with a 4 degree window, so the 19 degree head plays from 17 to 21 degrees. Mizuno publishes the ranges rather than a position-by-position chart.
What replaced the Mizuno ST-MAX 230 hybrid?
The Mizuno JPX One hybrids, launched for 2026.
Buying one
Mizuno has since introduced the Mizuno JPX One above it in the range, so the ST-MAX 230 is at the end of its retail life rather than fully retired — closeout stock still turns up at retailers, and hybrids one generation back are the sweet spot of the used market. Before buying used, check the stamped loft against the chart above and ask which hosel setting it is in — an adjustable hybrid may be set a degree or more away from the number on the sole, and sleeve adapters are brand- and generation-specific.
