About the Srixon ZXi RKT
The ZXi RKT is Srixon's 2026 driver family — announced 22 September and at retail from 16 October 2026 after a summer of tour seeding. The RKT Face system upgrades the i-FLEX variable face structure in a silicon-enhanced VR-Titanium alloy, carried on an "Acousticore" chassis whose AI-designed internal ribs tune both stability and sound under a carbon crown. The core RKT balances speed and workability with heel and toe weights, the LS adds front-to-back weighting for the lowest spin, and the MAX — Srixon's highest-MOI driver ever — runs a single 14 g rear weight. All three use the QTS 1.5 sleeve with twelve loft, lie and face-angle settings.

Frequently asked questions
What lofts does the Srixon ZXi RKT come in?
The core ZXi RKT comes in 9 and 10.5 degrees, the RKT LS in 8, 9 and 10.5 (8 right-hand only), and the RKT MAX in 9, 10.5 and 12 (9 and 12 right-hand only).
What is the ZXi RKT adjustment chart?
The QTS 1.5 sleeve has twelve settings covering ±1.5 degrees of loft. Each non-standard position also flattens lie by 0.5 to 3 degrees and moves the face up to 3 degrees closed (loft up) or open (loft down); 'FL' positions are the flat-lie variants.
What is new about the RKT face?
It upgrades Srixon's i-FLEX variable-thickness design in a silicon-enhanced VR-Titanium alloy, paired with a Variable Roll Design and a two-zone Rebound Frame — while the 'Acousticore' rib structure tunes the sound that bulked-up carbon drivers often lose.
Is the ZXi RKT the current Srixon driver?
Yes — it reached retail on 16 October 2026 as the replacement for the 2025 ZXi, which stays on sale alongside it at a reduced price while stock lasts.
Where it sits in the lineup
Introduced in 2026, the Srixon ZXi RKT is the current Srixon driver line as of October 2026, with no replacement announced. It replaced the Srixon ZXi. New heads are sold in the stock lofts charted above; the hosel settings extend each head beyond its stamped loft, so a loft between two stock options is usually reachable from either. 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.
