Stiff & Powerful Splitboard Binding

The Spark R&D Surge ST delivers a stiff, responsive ride for aggressive backcountry riders and big mountain lines. Designed for riders who demand maximum control in steep terrain and challenging snow conditions, the Surge ST pairs a solid baseplate with supportive asymmetrical components that charge hard without compromise.

Surge ST’s Asym Rip ‘N’ Flip highbacks use high glass fiber content for responsive power transfer, while the beefier Pillow Line ankle straps keep you locked into your turns when things get steep. With Tesla T1 technology, Smooth Touring (ST) Brackets and integrated ST Whammy Bars, touring transitions are smooth and efficient even on long skin tracks.

Built to withstand demanding backcountry use, the Surge ST combines durability with refined design details that make it a go-to binding for expert splitboarders chasing performance without excess weight.
