Product Info
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.
Product Details
Tour Mode
Improved ST (Smooth Touring) Mode – Spark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity.
ST Whammy Bars – Overmolded plastic blend where the climbing wire meets the baseplate to eliminate stickiness. (Note: not backward compatible with previous Arc, Surge or other older models)
ST Touring Brackets – Overmolded with low-friction proprietary plastic over and through the bracket holes in the aluminum base - strong, smoother pivoting, and lasts 4 times longer than the old brass bushing.
Hollow Pivot Pins – Made with stainless steel and hollowed out to be 33% lighter than standard pins
Baseplate
CNC Machined Baseplates – CNC machined baseplates remain solid for max stiffness and durability. All of the baseplate side windows have been partially filled to increase durability and strength
7075 Aluminum Heel Loops – 7075 Aluminum heel loops are thinner and lighter than our standard heel loops while maintaining the required strength.
Straps
Pebax® Pillow Line Straps, Ladders and Adjusters – Pebax® is a plastic commonly used in high-end alpine touring ski boots, It is stiff, tough and 20% lighter than the standard material used.
Buckles
Proven Burton Buckles
Highback
Carbon Reinforced Asym Rip 'N' Flip Highbacks – Asymmetrical design features individual left and right highbacks that slope inward matching the rider’s stance / The upper section is flatter for improved lateral mobility / More material at the base for increased longevity and durability / Higher bottom edge won’t snag on boots with crampon welts or soles that wrap high on the heel
Flippin’ FLAD toggles between your forward lean angle and -13° touring position for easy transitions.
Lateral slots for our BD Touring Strap for greater edge control while skinning.
Made with proprietary custom blended materials for improved strength and durability, while minimizing weight.
Tool free micro-adjustable from 0° to 22° for complete customization of your forward lean angle
Additional Features
7075 Aluminum Hardware – A 65% weight savings is found by replacing 7 stainless steel components with 7075 aluminum hardware, custom made in-house

Ability Level
Advanced-Expert Whether you charge the steepest lines, hit the biggest jumps in the park or carve with race-like precision, advanced to expert level skis, snowboards, boots and bindings are for the more aggressive rider. In skis and snowboards, you'll often find layers of metal, carbon or other stringers for rigidity and power, while advanced to expert level boots and bindings are usually on the stiffer side of the spectrum for rebound and precision steering.
