What Our Gearhead® Experts Are Saying: "These crampons are a lifesaver when the skintrack turns to ice. They’re incredibly easy to install thanks to the ST axle, and the lighter 7075 aluminum slices through firm snow with less drag. I barely notice them in my pack until I need them—then they’re worth their weight in gold." We count on the Spark R&D Ibex ST Pro Crampons when the skintrack gets steep, icy, and unforgiving. Designed with a 7075 aluminum body, these crampons are 30% lighter than the standard Ibex ST yet just as strong, saving energy on the approach without compromising bite. The slim profile cuts through snow with less drag, helping us move efficiently over firm terrain. The ST Tech axle makes installation and rotation smooth and simple, so transitions are quick when conditions change. A nesting dual-width design keeps the pair compact and easy to handle in the pack, while the included storage bag protects other gear. When steep climbs demand extra traction, the Ibex ST Pro ensures every step sticks.
