The Ibex ST Pro Splitboard Crampons are 4WD for your splitboard and are a necessity when the skintrack is firm or icy. They feature an overmoldeded ST Tech axle for easy installation and smooth rotation. Pro crampons are for splitboarders who want the best of the best - A 7075 aluminum crampon body is just as strong, but lighter and thinner than our standard Ibex ST. It slices through the snow even better with less drag, saving you valuable energy output on the skin track. Its dual-width design features one crampon that is slightly wider than the other, allowing the crampons to nest together for easy handling and reduced packing space.
