Spark R&D 25/26 Arc ST

Spark R&D 25/26 Arc ST

The Spark R&D Arc ST is a splitboard binding that shines in trees and powder and is tough enough for more complex all-mountain terrain. A cutout baseplate, medium flex highbacks and a lighter ankle strap save weight and give it a surfy ride down.

Why We Carry It

Spark is the name in splitboard bindings, and the Arc is the light, fun one we put most riders on.

Highlights

• Cutout baseplate: Saves grams for a lighter setup.
• Medium flex highbacks: Asym Rip 'N' Flip highbacks for a surfy, playful feel.
• Lighter ankle strap: Smaller strap with a flex window to cut weight.
• Tesla T1: Spark's binding interface for touring and riding.
• ST Tech: Thermoplastic over-molded on the ST Brackets and Whammy Bars reduces friction and improves durability.
• Complete kit: Comes with ST Brackets, T1 heel rests, mounting screws and a Spark Pocket Tool.
