The Singing Rock Lucifer ll Crampon is a new and improved version of the original Lucifer Crampon, and is one of the lightest crampons for technical ice climbing and mountaineering on the market. The Singing Rock Lucifer ll Crampon features low profile teeth, which are ideal for steep ice climbs, while the patented tool-less adjustment system allows for a quick, easy and precise fitting process. The Lucifer Crampon is available with a tech binding system or a semi-classic binding system, depending on what you want to use them for, and also has interchangeable front points, so you can go duo or mono.
