Specification summary adapted from forgiving.golf, CC BY 4.0. Original source observations: 2026-09-06. The named model's manufacturer page was reviewed 2026-10-02; this is not an independent measurement or a complete factory chart.
Identifying the right model
- Match the complete Quantum Max Fast name and any suffix on the head or package to the linked manufacturer page.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
