Spark R&D Arc ST Pro 2026

The Spark R&D Arc ST Pro is an exceptionally lightweight splitboard binding built for demanding backcountry days. Its carbon-reinforced highbacks, CNC-milled baseplates, 7075 aluminium hardware and Pebax Pillow Line straps reduce weight while delivering a stiffer, more responsive feel than the standard Arc.

Smooth Touring brackets minimise friction and wear, while the integrated ST Whammy Bar keeps crampons fully engaged as the heel riser changes position. The Tesla T1 system and Snap Ramp interface make transitions efficient, making this a strong choice for riders who prioritise uphill efficiency, durability and precise downhill performance.
