Description
Push your limits and go further into Utah’s backcountry with the Spark R&D Arc ST Pro Bindings, the pinnacle of lightweight performance and responsiveness, available now at Salty Peaks Snowboard Shop in Salt Lake City! Designed for the performance-driven splitboarder who demands the absolute best from their gear, the Arc ST Pro shaves critical ounces while boosting durability and precision for big days and technical lines.
The Arc ST Pro takes all the beloved features of the standard Arc ST and supercharges them with premium materials and custom components. The most significant upgrade is the carbon-reinforced nylon Asym Rip ‘N’ Flip Highbacks. These highbacks are lighter, more responsive, and stiffer than standard versions, yet still offer a surfy feel and excellent lateral mobility, allowing you to tweak and express your style while maintaining powerful control. The individual left and right highbacks are ergonomically designed for optimal comfort and control.
Weight savings are paramount for long tours, and the Arc ST Pro delivers. It features upgraded 7075-T6 aluminum hardware throughout, which is 65% lighter than standard stainless steel parts, including custom hex-drive screws that are less likely to strip. Even the pivot pins are hollowed out, reducing their weight by 33%.
The Pillow Line Straps are crafted from premium Pebax® plastics, a material often found in high-end ski boots. These straps are incredibly lightweight, durable, and maintain their flex consistency even in extreme cold. The ankle straps are designed for agile support, while the toe straps can be used as caps or traditional over-the-top straps.
Touring efficiency is built-in with Spark’s T1 System and ST (Smooth Touring) Tech. The Tesla Snap Ramps allow for effortless attachment and removal from your puck-compatible splitboard (pucks sold separately) – no pins or cables needed. The ST Whammy Bars are integrated directly into the baseplate and feature overmolded plastic for super-smooth transitions between stowed, 12°, and 18° climbing wire positions. The ST Touring Brackets are also overmolded with low-friction plastic for smoother pivoting and four times the durability of older brass bushings.
The Spark R&D Arc ST Pro Bindings offer a medium flex for a balanced feel that excels in powder and tree runs but is robust enough for technical all-mountain conditions. If you’re serious about splitboarding and every gram, every detail, and every ounce of performance counts, the Arc ST Pro is your uncompromising choice for ultimate backcountry freedom. Gear up at Salty Peaks and experience the difference.
