Product Info

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 PinsMade with stainless steel and hollowed out to be 33% lighter than standard pins

Improved ST (Smooth Touring) ModeSpark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity.

ST Whammy BarsOvermolded 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 BracketsOvermolded 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.


CNC Machined BaseplatesCNC 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 Loops7075 Aluminum heel loops are thinner and lighter than our standard heel loops while maintaining the required strength.


Pebax® Pillow Line Straps, Ladders and AdjustersPebax® is a plastic commonly used in high-end alpine touring ski boots, It is stiff, tough and 20% lighter than the standard material used.
