The all-new SPX 14 RACING is a competition-level race binding with an 5-14 DIN range and 80mm brake. The new SPX heelpiece combined with our reinforced Full Drive 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. The race-specific Maxflex bridge neutralizes pressure between toe and heel, delivering the most natural ski flex. The SPX 14 RACING is designed for use with R20, R18 or I-Box WC plates only.
