Product Info
Spark Arc bindings have been improved in just about every way over the summer, and the Spark R&D Arc ST Pro Splitboard Bindings go even further in their quest for the lightest and most efficient splitboard connection possible. Spark started by initiating their "ST" (Smooth Touring) program on just about any connection with inherent friction, and using a fresh overmolding process proceeded to drastically improve both performance and durability. With the Pro Series bindings, they jumped at any opportunity to cut weight without sacrificing performance, adding carbon to the highbacks, hollowing out the pivot pins, and substituting alloy hardwear for stainless steel where possible. The Arc ST Pro is the softer flexing of the company's offerings, best for those who prefer a surfier, more forgiving ride.
Product Details
Tour Mode
Hollow Pivot Pins – Made with stainless steel and hollowed out to be 33% lighter than standard pins
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.
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.
Tool free micro-adjustable from 0° to 22° for complete customization of your forward lean angle
Made with proprietary custom blended materials for improved strength and durability, while minimizing weight.
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
Intermediate-Advanced Whether you’re a progressing intermediate exploring new runs and terrain, or an accomplished rider seeking new thrills, the majority of skiers and snowboarders fall into this level. Intermediate to advanced skis and snowboards may be somewhat wider or stiffer than beginner-intermediate skis and snowboards, usually with a stronger wood core and sandwich sidewall construction. Intermediate to advanced boots and bindings range from softer flexing freestyle options to stiffer choices built for stability at speed.
