Spark R&D Arc ST Pro Splitboard Binding
The Spark R&D Arc ST Pro Splitboard Binding is the premium version of Spark's medium-flex binding for splitboarders who want the least weight on long tours and still want a surfy ride. Carbon-reinforced nylon highbacks, Pebax Pillow Line straps, 7075 aluminum heel loops and aluminum hardware replace heavier parts while keeping the Arc geometry. At 556 g per binding in a Medium, with Tesla T1 touring and an ST Whammy Bar at 12 and 18 degrees, the Arc ST Pro suits long tours, multi-day objectives and powder riding.

Why We Like It
- Carbon-reinforced nylon highbacks keep the Arc's medium flex and surfy feel while shaving weight.
- Pebax Pillow Line straps hold their flex in the cold and save weight over the standard straps.
- 7075-T6 aluminum hardware replaces seven stainless steel parts, with hex heads that resist stripping and hollow pivot pins.
- Smooth Touring brackets and the ST Whammy Bar keep the touring side quiet, with risers at 12 and 18 degrees.
Best Uses
- Long tours and multi-day objectives
- Powder and tree riding
- Riders who want the lightest Arc
- Soft boot splitboarders, XS to Large
- Big objectives where weight matters
Mounting and Setup Advice
Spark sizes its bindings in one unisex line from XS to Large, so choose on boot size; the 556 g figure is for a Medium.
On the board side, the binding needs Spark Flat Pucks or Spark Canted Pucks, sold separately, and then works with any puck-compatible splitboard. If you are mixing hardware generations, ST bindings need ST Whammy Bars, while ST bindings run on older Tesla brackets. Bring your board in so we can set puck placement and stance.
