THE SURGE ST PRO

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.

Spark took the ready-to-rage Surge ST binding and went over every component with a fine-toothed comb looking for ways to improve performance and drop weight. The product of that effort is the new Spark R&D Surge ST Pro Splitboard Bindings, and they're a thing of beauty. When you can't afford to give up performance going uphill OR downhill, and you're going deep enough for every gram to count, the Surge ST Pro is the way to go.

Gram Counting

A 65% weight savings is found by replacing 7 stainless steel components with 7075 aluminum hardware, custom made in-house. 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.
