Spark R&D Arc ST Pro Splitboard Binding

The Pro version focuses on weight reduction and material upgrades. It utilizes premium, lightweight materials and extensive baseplate cutouts to shave off weight without sacrificing the structural integrity required for backcountry riding.

Yes, the Arc ST Pro uses the T1 binding system and Tesla Snap Ramps, which are the industry standard for splitboard interfaces. They are compatible with virtually all splitboards currently on the market.

The Asym highbacks are shaped to match the natural contours of your lower leg. This design provides a more surfy, responsive feel, allowing for better lateral mobility while maintaining the support you need for aggressive turns.

The flex window is designed to allow the strap to bend naturally with your boot during movement. This improves overall mobility and comfort, especially during long days of touring where repetitive motion can cause pressure points.

No, this is a comprehensive package. It includes the ST Brackets, T1 Heel Rests, aluminum mounting screws, and even a Spark Pocket Tool, so you have everything required for installation right out of the box.

These bindings weigh 522 grams per binding, or 2.44 lbs per pair. This lightweight construction is specifically engineered to reduce fatigue during long ascents, making them a top choice for weight-conscious backcountry enthusiasts.
