The moderate-flexing Spark R&D Arc ST Splitboard Bindings get a slew of improvements for the new season. The most significant include upgraded hardware almost anwhere that sees friction during the skinning action. Bindings with the "ST" - or "Smooth Touring" - moniker have overmolded components with low-friction plastic over an interior metal structure, making them smoother, quieter and more durable. The Asym Rip 'N' Flip highbacks are also re-designed for better fit and functionality, and the pivoting action at the bracket is much improved with ST tech added. If your idea of splitboarding is more surf than huck, check out this well thought-out design before you pull the trigger on a binding system.
