Spark R&D Arc ST Pro Splitboard Bindings – Ultralight Back-Country Performance

The Spark R&D Arc ST Pro Splitboard Bindings are engineered for the rider who demands the lightest weight, highest performance and full back-country responsiveness. With premium materials, lightning-quick touring tech and downhill capability, these bindings let you move fast uphill and rip hard downhill.

Featuring carbon-reinforced nylon high-backs, Pebax® molded straps, CNC-machined baseplates and the proven ST (Smooth Touring) system, the Arc ST Pro offers intuitive transitions, minimal weight and maximum control. Ideal for splitboarders chasing remote lines, long climbs and deep powder across Canadian terrain.

Tour Mode to Ride Mode, Seamlessly

With Tesla Snap-Ramps, ST Whammy Bars (0°, 12°, 18° climbing positions) and T1 bracket compatibility, switching between touring and riding is smooth. The bindings slide in, lock securely, and you’re ready. On descent, the baseplate cut-outs, asym high-backs and flex-window Pillow Line straps deliver surfy, responsive performance.

Built for the Canadian Back-Country

Every component is optimized: ultra-light hardware (7075-T6 aluminium), hollow pivot pins, over-moulded bushings reducing friction and durable plastics that perform in cold, wet conditions. Whether skinning through spring slush, climbing steep couloirs or riding deep pow, the Arc ST Pro stands up to the demands.
