Rossignol SPX 10 B73 is an all-new, high-performance alpine ski binding with a 3-10 indicator range and 73mm brake. The all-new SPX heelpiece combined with our reinforced Full Action toe delivers the industry's strongest coupling strength (boot-to-binding interface) for maximum power transmission, precision, and control. Featuring the longest elastic travel on the market, SPX bindings also provide superior shock absorption, reducing unwanted pre-release for dependable, trustworthy alpine performance. And with a substantial reduction in weight, reduced ramp angles for a more neutral, upright stance, and improved step-in/step-out functionality, the SPX offers less fatiguing, more user-friendly alpine performance for committed all-mountain, freeride, and freestyle skiers. Recommended for Ski Width: 64-73mm.
