The new SPX Rockerflex features a smaller mounting zone and partially suspended heelpiece, allowing enhanced ski flex and control. Combined with our reinforced Pivot toe, the SPX Rockerflex 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. The race-specific Rockerflex bridge neutralizes pressure between toe and heel, delivering the most natural ski flex.
