New Grivel Crampons Grivel G12 Dualmatic Evo crampons These are Dualmatic crampons with interchangeable front bails for both Newmatic andmatic binding systems. Grivel's G12 crampons are suitable for difficult winter traverses and alpine routes. Compared to the "Air Tech" series, the points are longer, and the second points are angled slightly forward, making them suitable for steep slopes. In addition to the Transformer Bail M, clamp-matic bail hangers (narrow bails) are included, allowing you to swap the bails to match the type of mountaineering boots you use. Only mountaineering boots with a heel welt are compatible. The heel features a binding system. The heel is equipped with a spring heel plate that can be adjusted in size by lifting it with your fingers.
