Grivel G12 Crampons Evo

Excellent 12-point semi-rigid steep ice, snow and mixed crampon with simple no tools adjustment. This crampon has long penetrating points and is designed for quite technical ice climbing, though it is still a reasonable walking crampon. However anyone needing a crampon mainly for walking and easier routes should consider the Air Tech.

There are three binding systems available:
Cramp-o-Matic: Full step-in with a wire front bail and fairly rigid bar. It's quick to put on in a blizzard and feels more rigid and secure than the other bindings, but you do have to get them on just right - rigid boots only. Fit only to a B3 Mountaineering Boot.
New-Matic: Semi step-in with Grivel's excellent plastic toe cap and fairly rigid bar - but will will fit only on semi-rigid B3 walking boots and stiffer, with a step in on the heel.
New-Classic: Superb all encasing basket system that means that you can put this crampon on just about anything that is B2 rated or above and it is supplied with a flexi-bar rather than a rigid one, making it more suitable for walking.

Antibott (anti-balling plates) are included.

This Evo model has three major changes over the previous version:

1. New heel lever is lighter and has only one moving part (as opposed to five) but still adjusts to all suitable boots.
2. The webbing tape is narrower (12mm as opposed to 14mm) and lighter.
3. The buckle has been redesigned to be lighter and more compact but still give a strong hold.

All this means that Cramp-o-Matic and New-Matic models are 54g lighter that their predecessors, whilst New-Classic models are 14g lighter.

Top Tip 1: For Cramp-o-Matic and New-Matic models, to fit smaller boots, take the bars out, and swap them over, turning them upside down before fitting them. This brings a small blocking lug into play, effectively shortening the length of the bar.

Top Tip 2: If you have problems fitting the Super-Asymmetric bars, take off the AB plates, and you can then slide them in from underneath.
