Spark R&D Arc ST Bindings, Large, Black — Demo

The Spark R&D Arc ST is a lightweight splitboard binding designed for riders who prioritize a surfy, responsive feel on the descent while maintaining efficient touring performance on the climb. Excelling in trees, powder, and playful terrain, the Arc ST remains tough enough to handle variable all-mountain conditions.

A cutout baseplate design, medium-flex Asym Rip ‘N’ Flip highbacks, and a smaller ankle strap with a flex window reduce weight and allow natural board flex, delivering a smooth, intuitive ride on the descent. Built on Spark R&D’s proven Tesla T1 system, the Arc ST offers fast transitions and reliable performance in real backcountry conditions.

Smooth Touring (ST) Tech is integrated into the ST Brackets and ST Whammy Bars, using a proprietary thermoplastic blend molded over metal components to reduce friction, increase durability, and improve touring efficiency on the skin track.
