Spark R&D Surge ST Pro

The 'Pro' designation indicates a focus on weight reduction and high-end materials. While the standard Surge is built for durability, the Pro version utilizes carbon-reinforced nylon highbacks and custom 7075-T6 aluminum hardware to shave significant weight without compromising the stiff, responsive feel.

The Surge ST Pro uses the Tesla T1 mounting system, which is the industry standard for Spark R&D bindings. As long as your splitboard is equipped with standard pucks or a compatible T1-ready interface, these will mount seamlessly.

The ST Whammy Bar is integrated directly into the baseplate, allowing you to engage or disengage the climbing wire using your pole basket. This eliminates the need to bend down or fiddle with small parts, making transitions on steep terrain much faster and more efficient.

Yes, the straps are molded from Pebax plastic, which is specifically chosen for its ability to remain flexible and durable across a wide range of temperatures. They are also waterproof, so they won't absorb moisture or freeze up during long days in the mountains.

The stiff flex is designed for demanding backcountry missions where precise control and support are critical, particularly on steep, icy, or technical terrain. If you are a beginner, you may find them less forgiving than a medium-flex binding, but they offer excellent power transfer if you prioritize performance.

No, the Surge ST Pro features a tool-free forward lean adjuster. You can quickly dial in your preferred angle on the fly, which is helpful when switching between skinning and riding modes.
