The 2022 Spark R&D ARC PRO Series Splitboard Binding is the lightest, and highest performing splitboard bindings in the world
Made with extreme attention to detail, premium materials, and custom components. Our PRO Series bindings are the culmination of our years in the forefront of splitboard binding technology and manufacturing. We built these for splitboarders who want the best of the best.
Gram Counting: A 65% weight savings is found by replacing 7 stainless steel components with custom-made 7075-T6 aluminum hardware. Not only is the pro hardware lightweight, it also adds splitboard specific features. We switched from phillips to hex heads where we could, making screws less likely to strip. We also crafted our aluminum heel loop screw with a custom screw head shape that has more than double the drive depth of a standard button head screw to avoid stripping. Additionally, an unthreaded shoulder improves the connection with the heel loop.
Full Pebax plastics in Pillow Line straps, ladders, & adjusters: Pebax is a premium material most often found in high-end ski boots as it provides consistent stiffness and improved toughness in cold temperatures. It’s also 20% lighter than our standard material.
7075 aluminum heel loops: 7075 Aluminum heel loops are thinner and lighter than our standard heel loops while maintaining the required strength.
Carbon reinforced nylon highbacks: Carbon reinforced highbacks are more responsive, lighter, and stiffer than our standard glass reinforced highbacks. Injection molding allows for more complex geometry and improved impact strength compared to other methods of carbon fiber construction.
Hollow pivot pins: Made with stainless steel and hollowed out to be 33% lighter than standard pins.
