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

The ZX Mk II family is the broader line: 3 heads against 2 — ZX5 and ZX7 for the ZX, ZX5 Mk II, ZX5 LS Mk II, and ZX7 Mk II for the ZX Mk II.

The ZX is sold from 9.5° to 10.5°, the ZX Mk II from 8.5° to 10.5°. Only the ZX Mk II has a stock 8.5° option.

Adjustability is a wash: both use the same hosel system (Quick Tune System (QTS) sleeve, ±1° of loft, 12 settings), so a given head reaches the same effective loft window in either generation.

The ZX Mk II arrived 2 years after the ZX as its replacement. Driver 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 ZX Mk II is the newer generation, so it carries the current face technology and full retail availability; the ZX 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: Srixon ZX driver specs and Srixon ZX Mk II driver specs.
