Spark R&D Arc ST PRO Splitboard Bindings - 2025

Spark R&D created the 2025 Arc Pro ST Splitboard Bindings for splitboarders who demand the most from their gear and are looking to save weight without compromising on durability or performance allowing you to push further and deeper into the backcountry.

The 2025 Arc Pro ST Splitboard Binding features all of the same key attributes of the Arc ST including the Asym highbacks, minimalist design, medium flex pattern ideal for trees and surfy pow turns, and the same snap ramps/side connections making transitions quick and easy. However, Spark has upgraded the materials in the components to make this binding even lighter without skimping on durability. Utilizing full Pebax® plastics for the straps, ladders and adjusters, similar to what is found in high-end ski boots, Spark was able to decrease the weight of these components by 20%. The Pro model features 7075 aluminum in the heel loops resulting in a thinner and lighter attachment point that doesn't sacrifice strength. Additionally, custom hardware and screws made from 7075-T6 aluminum allow for dramatic weight savings over their stainless steel counterparts. 

The Arc Pro ST is one of the lightest splitboard bindings on the market designed for the backcountry explorers putting in long days in the skin track, whether that's in the Gore, the Tetons or the Canadian Rockies.
