Grivel G12 LT Cramp-O-Matic Evo automatic crampons

The G12 LT Cramp-O-Matic Evo by Grivel is a lightweight 12-point steel crampon for classic and technical mountaineering and glacier walking, representing the latest evolution of the historic model long recognized as the "King of Crampons." The configuration of its 12 steel points ensures constant and secure traction on snow, ice, and mixed terrain, promoting safe movement in variable alpine conditions and on treacherous alpine ground. Thanks to the exclusive LT construction, this model reduces the overall weight of the steel frame through finely optimized material thickness, while maintaining durability and structural robustness for repeated use over time. The construction is designed to balance flexibility and support underfoot, while safety is enhanced by the proven proactive Antibott system at the front and rear, which reduces snow buildup and prevents the formation of balling during use. This specific version adopts the Cramp-O-Matic Evo attachment system (marked COM), a fully automatic closure mechanism with a front metal bracket and micrometric rear lever, ideal for rigid mountaineering boots equipped with notches on both the toe and heel. With a fit that covers sizes from 36 to 47 and an overall weight of 861 grams per pair, the crampon is certified according to the strict CE EN 893 and UIAA 153 standards. Finally, it utilizes the Grivel Crampon System technology, which allows for the use of interchangeable components and compatible accessories available separately for precise configuration.
