DEMO Srixon ZX7 Mk II men's driver, Right Hand, 9.5°, 6.5 (X-Stiff)

The Srixon ZX7 Mk II is the most workable and adjustable driver in the Srixon ZX Mk II family, purpose-built for better players and high-swing-speed golfers who demand precise control over their ball flight. Its compact, tour-preferred silhouette delivers a low-spin, penetrating trajectory, while the enhanced Rebound Frame technology and dual swappable sole weights give serious players every tool they need to shape shots with confidence. This driver is offered as a DEMO club in 10/10 condition — virtually indistinguishable from new — and is supplied without a headcover. Fitted with the elite Project X HZRDUS Gen 4 Black 60 shaft in 6.5 (X-Stiff) flex, this is a driver ready for the fastest, most aggressive swings on the tee.

• Rebound Frame with Dual Flex Zones — A stronger Rebound Frame design incorporates two independent flex zones that work simultaneously to deliver a purer transfer of energy from face through ball, producing maximum ball speed and added distance on every strike.
• Ti51AF Titanium Alloy Variable Thickness Face — The advanced Ti51AF titanium alloy face uses an intricate variable thickness pattern that is thinner at center and thicker at the perimeter, expanding the high COR area by 10% over the previous generation for improved ball speed on off-center hits.
• Star Frame Crown — An internal latticework of ridges allows the titanium crown to be made extremely thin, freeing up discretionary weight that is redistributed low and forward for optimal launch and spin characteristics.
• Dual Swappable Sole Weights — The ZX7 Mk II is the only driver in the Srixon Mk II lineup to feature two interchangeable heel and toe sole weights. Stock configuration ships with one 4g and one 8g weight; weights are available from 2g to 14g, letting golfers promote a draw or fade and fine-tune swing weight with precision.
• 12-Position Adjustable Hosel — The hosel sleeve offers 12 combinations of loft, lie, and face angle, giving players a wide window to dial in their preferred launch conditions without changing shafts.
• Project X HZRDUS Gen 4 Black 60 Shaft (6.5 X-Stiff) — Fitted with the flagship Project X shaft, featuring a proprietary Dual Torsional Design that creates a stiff butt, X-stiff midsection, and stiff tip profile — delivering low launch, low spin, and ultra-stable control for the most aggressive swingers, with 60g weight and 3.3° torque.
• Compact Tour-Preferred Address — The matte black crown and smaller front-to-back footprint produce a clean, classic look at address that inspires confidence in shot-shaping, with a pleasant acoustic profile refined from the previous generation.
• DEMO Condition 10/10 — No Headcover — Offered as a DEMO unit in pristine 10/10 condition. Please note: no headcover is included with this club.

Key Technologies Explained

Rebound Frame

Most drivers rely on a single flex zone — the face itself — to generate ball speed at impact. Srixon's Rebound Frame adds a second flex zone: a thin ring of titanium set back from the face that deforms outwardly as the face deforms inwardly. These two zones act in unison like a spring within a spring, rebounding together to deliver an unprecedented energy transfer into the ball. The result is a measurably purer and more powerful rebound effect that elevates COR across the entire face and translates directly into more ball speed and distance.

Variable Thickness Face (Ti51AF)

Behind the high-strength Ti51AF titanium alloy face lies a complex thickness map. By making the face 0.25 mm thinner at its center and 0.4 mm thicker at the perimeter compared to the previous generation, Srixon engineers expanded the high-COR zone by 10%. This means that mis-hits toward the heel or toe retain significantly more ball speed, reducing the distance penalty for shots struck away from the geometric center.

Star Frame Crown

The Star Frame is an internal structure of latticework and reinforcing ridges bonded to the underside of the titanium crown. This architecture provides structural integrity while allowing the crown itself to be made exceptionally thin — far thinner than a conventional single-piece titanium crown. The weight saved is then repositioned as discretionary mass that is placed low and toward the face to optimize launch angle and minimize unwanted spin.

Project X HZRDUS Gen 4 Black — Dual Torsional Design

The HZRDUS Gen 4 Black is Project X's flagship wood shaft, built around a proprietary Dual Torsional Design process that allows engineers to precisely dial in torsional stability along each section of the shaft independently. The outcome is the classic HZRDUS Black stiffness profile — stiff butt, X-stiff midsection, stiff tip — but with a noticeably smoother, more responsive feel than earlier generations. At 60g with 3.3° of torque in 6.5 (X-Stiff) flex, it delivers a low-launch, low-spin ball flight engineered for players with fast, aggressive swings who need maximum stability without sacrificing feedback.
