Spark R&D Arc ST 2026 Fijaciones Splitboard

Lightweight, agile and touring-friendly – the Spark Arc ST

The Arc ST is the ideal choice for riders aiming to conserve energy on the ascent while maintaining performance on the descent. It features a lightweight build, surfy flex, and smart engineering. With the refined ST components, hiking movements feel smoother and more efficient, making it perfect for long tours, powder missions, and navigating tight tree lines.

Highback
The asymmetrical Rip ‘N’ Flip Highback provides lateral flex while offering responsive support. Its flatter top section enhances freedom of movement when traversing or riding in a playful style. The split-specific forward lean adjuster makes switching between hike and ride modes quick and effortless.

Baseplate
The CNC-machined baseplate, featuring large cutouts, reduces weight and enables on-the-fly stance adjustments without the need to remove the binding. The integrated ST Whammy Bar climbing wire provides smooth transitions between 0°, 12°, and 18° positions. ST Touring Brackets with thermoplastic bushings ensure friction-free touring strides.

Straps
The one-piece Pillow Line Straps are waterproof, ultralight, and designed for comfort. The low-profile Arc Ankle Strap with a built-in flex window wraps perfectly around the boot, offering plenty of freedom of movement.
