O’Brien Siege Slalom Ski w/ Z9 Binding & Rear Toe Plate

O’Brien Siege Slalom Ski w/ Z9 Binding & RTP

Featuring a high-performance Tournament-Crossover architecture, the O’Brien Siege is the definitive mechanical solution for skiers requiring aggressive edge hold with the stability of a wider-ride ski. This slalom ski utilizes Step-Down Rails to deliver superior hydrodynamic lift and surgical precision in turn-finishing. The hardware architecture focuses on micro-adjustable precision, utilizing the Z9 Binding to provide a secure data-free physical connection paired with a Rear Toe Plate (RTP) for customized rear-foot freedom and tensioning.

Technology-driven Fiberglass/Carbon Hybrid laminates provide a specialized shield against energy loss, ensuring constant speed through the wake. The Siege focuses on ownership value through its ability to perform at speeds up to 34mph while maintaining the forgiveness of its Convex Slide-cut profile. Reliability is supported by the 316 stainless steel fin hardware and industrial-grade construction designed to mitigate oxidation in high-salinity environments. This setup is the ideal choice for athletes prioritizing high-output energy transfer and professional-grade carving continuity.
