The Spark R&D Arc ST Splitboard Bindings have improved dramatically over time, with their ST (Smooth Touring) overmolded design making the bindings super quiet and virtually friction free. Now the Spark R&D Arc ST Pro Splitboard Bindings up the ante with Pebax® (a plastic commonly used in AT ski boots) straps, ladders and adjusters, lighter but equally strong 7075 Aluminum heel loops, and re-designed hardware with Hex head and better anchoring at the heel loop.
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.
