Grivel Air Tech crampons


It's finally winter, I'm at my base in the French Alps, and ice is forming on waterfalls... Last season Duncan and I tested these crampons on our favourite multi-pitch waterfall, the Cascade du Mone, below the Bellecote massif in the Rosuel valley, and soon it'll be time to get them back into action (note: January 2nd 2015: the ice is in condition! Just had a great session there on the first 3 pitches). They are a steel 12-point crampon with New Matic harness: front cradle and rear throw.  This can only be used on boots with a rear ledge; the harness system of front and back cradles is New Classic (plus Cramp-o-Matic with front and rear bails). Air Tech has cunning size-adjustment: the bar can be reversed to shorten the crampon to fit a size 3 boot, so unusually this 12 point crampon works for large and small boots. Two well-placed heel stoppers located the boot accurately and firmly. Thumb-screw adjuster on heel throw allows it to fit all depths/size of ledge. Patented anti-ball plates are sprung to eject snow; they’re brilliant. Webbing slides, tightens, locks, releases easily courtesy of double D-rings and a rubber release toggle. Design of teeth covers wide spectrum of use. Security on snow and ice was excellent. I used these for walking, glacier travel and grade-three ice climbs (using Scarpa Charmoz Lady boots), and trusted them implicitly.
