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.
Hosel adjustment chart
Quick Tune System (QTS) sleeve · loft ±1° · 12 settings.
The sleeve adjusts lie flatter alongside loft; Srixon's per-position values for this generation are no longer published. Face angle moves with the loft setting, opening as loft is removed and closing as it is added.
Srixon's ZX-era QTS offered twelve combinations of loft, lie and face angle across ±1° of loft. The position-by-position chart for this generation is no longer published online, so it is not reproduced here — note that it is not the same chart as the later QTS 1.5 sleeve on the ZXi, whose range is ±1.5°.

About the Srixon ZX Mk II
The ZX Mk II is Srixon's 2023 driver generation, refining the original ZX's Rebound Frame — alternating rigid and flexible zones that return more energy to the ball — under a carbon crown. The ZX5 Mk II is the mid-spin, high-MOI volume seller with a single rear weight; the ZX5 LS Mk II moves its sole weight forward near the face to cut spin for faster swings (and adds an 8.5° head); and the ZX7 Mk II is the tour head with two swappable heel/toe weights for draw or fade bias. The ZXi replaced the family in January 2025.

Frequently asked questions
What lofts does the Srixon ZX Mk II come in?
The ZX5 Mk II and ZX7 Mk II come in 9.5 and 10.5 degrees; the ZX5 LS Mk II adds an 8.5 alongside 9.5 and 10.5. The QTS sleeve extends each head one degree either way.
How adjustable is the ZX Mk II hosel?
The Quick Tune System sleeve offers twelve combinations of loft, lie and face angle across ±1 degree of loft. Srixon no longer publishes the position-by-position chart for this generation — and it differs from the ±1.5 degree QTS 1.5 chart on the newer ZXi.
What is the difference between the ZX5 Mk II and ZX7 Mk II?
The ZX5 is the higher-MOI, mid-spin distance head with a single rear weight; the ZX7 is the compact tour head whose two heel/toe weights swap to set draw or fade bias.
Is the Srixon ZX Mk II still in production?
No — the ZXi replaced it in January 2025 and Srixon's own product pages for it are gone, so the used market is the source. Check which QTS setting a used head is in before judging its loft.
Buying one
Srixon has since introduced the Srixon ZXi above it in the range, so the ZX Mk II is at the end of its retail life rather than fully retired — closeout stock still turns up at retailers, and drivers 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 driver may be set a degree or more away from the number on the sole, and sleeve adapters are brand- and generation-specific.
