These are used Rossignol Cut Stage 2 or Stage 3 Shaped Snow Skis. The 140, 150 and 160cm lengths are stage 2. The 170, 177 and 184cm lengths are Stage 3. These are a great pair of All Mountain skis. These are from Rossi's Quick Cut line, made for the intermediate to advanced skier. They have a mid flex design for precise turning response and more control. The wide tip will initiate turns easily while the rounded tail releases smooth for an easy fluid transition throughout the whole turn. With its aggressive side cut and 16m radius (16M @ 170cm), the Cut Stage 2 or Stage 3 is an excellent ski for speed carving the groomed runs and will also perform great in the bumps. These are a great pair of skis to enjoy all over the mountain!!!
