With the Sarken Front Sections you get a pair of front parts of the Petzl Sarken crampon. You can use the front parts either as spare parts or combine them with rear parts of other crampons by Petzl. This way you don't need to buy a completely new pair of crampons but only the relatively cheap front part. Thus, you can transform moderate mountaineering crampons to very technical Sarken crampons. The Sarken has front points with a T-profile and provides a good combination of great grip on ice and load capacity on hard snow.
