Tech Specs
Spark R&D developed the Pro Series of these bindings to create the binding that would withstand the demands of pro riders who won't compromise on weight and performance. The Arc Pro ST splitboard bindings are for riders trekking deeper into the backcountry and higher on surrounding peaks. Aside from switching to hardboots, the Spark Arc Pro ST bindings are the lightest weight soft boot bindings on the market at 557 grams in a Medium. The Spark Arc Pro's have a medium stiff highback and are preferred for riding trees, having a surfy feel overall, and are suited for the longest of days.
This binding is built around Spark's trusty T1 Tesla chassis. It can be used with regular or canted pucks and slides on easily under the Tesla Snap Ramps. They've removed all the material they could to keep the baseplate light and allow riders to use the mini backcountry jig and bindings to make a stance adjustment in the field. The bindings feature custom-made 7075-T6 hollowed-out aluminum hardware with a 33% weight savings.
The Arc Pro highbacks are carbon-reinforced from an injection mold. This creates a stiffer, lighter, and ultimately more responsive ride downhill. Adjust the forward lean by twisting the lever that rests on the heel cup in downhill mode. Arc Pro heel cups are 7075 aluminum, which makes the heel loop thinner yet just as strong. Upgraded materials in the components to make this binding even lighter without compromising durability. The full Pebax plastics for the straps, ladders and adjusters are the same material found on high-end ski boots. This 20% weight savings is another reason why Spark Arc Pro's are the lightest soft boot bindings on the market.
You can see this binding in nearly any splitboard movie from the Tetons, Colorado, the PNW, Canadian Rockies and all the way in the European Alps. This binding is trusted by our shop techs and our riders. You can't go wrong with the best bindings on the market.
