Spark ARC ST

The Spark ARC ST is a lightweight splitboard binding built around Spark’s T1 Tesla base, with fast puck engagement and a smooth transition between touring and riding modes. Its aluminum trellis base delivers a responsive connection to the board, while the adjustable heel lift and Whammy Bar provide practical support on climbs.

Designed for backcountry riders who value low weight without sacrificing downhill sensitivity, it combines durable construction with forgiving straps and a comfortable, efficient touring setup. It suits splitboarders seeking quick transitions, dependable ascent performance and confident control on the descent.
