What Our Gearhead® Experts Are Saying: "I grab the Surge ST when I know the terrain is going to be steep and demanding. The stiff highbacks give me tons of control on technical descents, and the ST tech keeps skinning smooth and efficient. They’re my go-to when I want maximum confidence in big terrain." When big terrain calls, we rely on the Spark R&D Surge ST Splitboard Bindings for the stiff, responsive feel that gives us control in consequential zones. Trusted by pros and local chargers alike, the Surge ST is built for riders who push steep lines, technical faces, and long backcountry missions where gear failure isn’t an option. With glass fiber-reinforced Asym Rip ‘N’ Flip highbacks and supportive Pillow Line straps, the Surge ST is tuned for powerful response without sacrificing comfort. Touring efficiency comes standard with Smooth Touring (ST) tech, which reduces friction and increases durability with overmolded thermoplastic in the brackets and Whammy Bars. Seamless transitions, easy climbing wire adjustments, and tool-free forward lean toggles keep us moving efficiently in variable conditions. From skintrack to summit to descent, the Surge ST delivers the stability and confidence we demand in serious terrain.
