The SP Crampones are adjusted to the new SP SLR SPlit Binding. It is easy to mount, just push it in the sliderplate from behind and the mould will fix it at your binding. So it is well positioned and ready to use. While hiking the crampon comes out of the snow and it saves your energy in steep areas. Due to the cutouts the crampon is lightweight but durable.
Best thing is to purchase the crampons together with the binding, so you will be safe on tour.
