The G20 is Grivels' most recent technical crampon, and the lightest of the new wave of lighweight, monopoint, technical 'poons...here's what Grivel have to say about them;

"The evolution of the modern technique of climbing ice push towards a more fluid motion, more elegant and faster, therefore it demands a crampon that makes it possible: a technical crampon, and a super-light one. G20 is a crampon 100% technical, reliable, efficient and the LIGHTEST IN THE WORLD: less than 800 grams per pair! The new MONO-RAIL technology (patented) distributes the 12 points in an intelligent and original way."
