Spark R&D Arc ST Splitboard Binding

Spark R&D Arc ST Splitboard Binding

Light, surfy splitboard bindings built to flow through pow and trees, tough enough for more technical terrain. Spark's Smooth Touring upgrades and the Tesla T1 system keep transitions simple.

Why We Carry It

Spark keeps it simple and bombproof. The Arc ST is the split binding we point most backcountry riders toward.

Highlights

• Tesla T1 with Smooth Touring: Bindings slide into offset ST Brackets and lock with the snap ramp. No pins, no cables, and the overmolded ST bushings cut friction and outlast the old brass ones.
• ST Whammy Bar: Built in climbing wire flips from stowed to 12 or 18 degrees for steep skin tracks.
• Arc ST Asym Rip 'N' Flip highback: Medium flex, left and right specific, with a tool free forward lean adjuster that flips to tour mode.
• Cutout baseplate: Saves weight without giving up a solid ride down.
• Pillow Line straps: One piece molded straps that won't soak up water or freeze. The Arc ankle strap is smaller with a flex window for agility.
• Cold proof plastics: Ladders and adjusters hold their flex from spring tours to subzero days, with Burton buckles.

Best For

Splitboarders who want a light, playful binding for powder laps, tree runs and long skin track days, like a tour up Mayflower Gulch.
