Spark R&DArc ST 2025 Splitboard Bindings

Light and surfy

The Arc ST offers every splitboarder an unparalleled touring and riding experience. The lightweight binding with medium flex straps and highbacks is great for any backcountry terrain and is also tough enough to handle more complex all-mountain conditions. The ST Touring Brackets and ST Whammy Bars make this binding even more efficient for touring.

Tesla T1 Splitboard Technology
The T1 binding system is one of the most well-known, user-friendly, reliable and efficient splitboard systems on the market. The binding is inserted into the touring brackets from the side and then locked with the snap ramps. No tools, no pins, no cables and no fiddling around.

Highback
The Asym Rip 'N' Flip Highback has a medium flex for a surfy ride. The Rip 'N' Flip Highback can be changed from touring mode (-13°) to riding mode in seconds with a small lever. The side cut-outs are compatible with Sparks Strappy Strap, which gives you even more support on the ascent.

Baseplate
A CNC-milled aluminium baseplate with maximum recesses provides power and lightness. In addition, the recesses allow you to make small adjustments to the binding angle without removing the binding. The ST Whammy Bar ascender is built into the baseplate, saving you extra weight.

Straps
The Pillow Line Straps come in a one-piece moulded construction. This makes them lightweight, durable, comfortable and waterproof.
