Spark R&D Arc ST 2026

The Spark R&D Arc ST is a lightweight splitboard binding built for efficient backcountry travel. Its CNC-milled baseplate, medium-flex highbacks and comfortable Pillow Line Straps create a responsive yet forgiving ride, while the durable construction stands up to demanding conditions.

The Smooth Touring brackets reduce friction and wear during transitions, and the integrated Whammy Bar heel riser keeps crampons fully engaged. With the Tesla T1 system and practical touring features, it suits splitboarders who prioritize low weight, comfort and dependable performance on long mountain days.
