A classic 12 point crampon designed for general mountaineering, mixed ice and rock climbing, and less extreme waterfall climbing situations. The entire G12 crampon is manufactured from Chromoly steel using new technology which is exclusive to Grivel at this time. Called "3 Dimensional Relief Stamping (3DRS)", this process increases the strength and rigidity, not only of the crampon's frame, but of each individual point as well.
Four "anti-shear" points, perpendicular to the line of the boot, improve security during descents. The crampons are fully adjustable by hand, without tools and one size fits all. G12 is easily collapsed for transportation.
By placing a bolt (included) through the front of the arch piece, it will remain centered, reducing the overall length of the collapsed crampon. In addition, the entire adjustment mechanism may be replaced with a simple nut and bolt; while this reduces weight, future length adjustments will require tools.
The ratio between quality, strength and weight is quite impressive; G12 is a true all purpose crampon. It represents the State of the Art in production - the result of 70 years of experience in design and manufacturing.
