Grivel G20+ LT Cramp-O-Matic Crampons

When the terrain gets steep, technical and vertical, your crampons need to be precise, and you won't get any more precise than the G20+. The Grivel G20+ LT Cramp-O-Matic is a lightweight, Mono-Point crampon built for pinpoint ice climbing, dry tooling and mixed climbing, combining a highly supportive steel chassis and the option of Ballistic Katana steel or Forged.

Cramp-O-Matic is designed for boots with front and rear welts (B3 Boots).

The G20+ LT's modular front section is part of Grivel's Crampon System (G.C.S.), allowing components to be changed and the crampon adapted as your objectives evolve. Alpine front points are also available separately, giving you the option to configure the G20+ LT for a broader range of mountaineering applications.

Despite its technical credentials, the LT construction keeps weight under control, with optimised material thickness reducing unnecessary bulk while retaining the strength and durability needed for serious use. The steel rear frame provides solid underfoot support, while Proactive Antibott plates front and rear help prevent snow build-up, keeping the crampon biting rather than turning into a pair of snowshoes.

At 821g per pair, the G20+ LT is low in weight and uncompromising in technical performance. Whether you're climbing steep winter lines, tackling alpine mixed routes or pushing up vertical ice, this is a crampon designed to give you super precise front-point placements, dependable support and the durability to keep coming back for more.

Binding Options

Cramp-o-Matic

• Full step-in bindings with front bail and heel lever-lock, for rigid boots with a heel notch. Suitable for B3 Boots.

Front Point Options

• Katana Ballistic Steel: 

  G20+ Katana Front Points provide high wear resistance and sustained precision in demanding terrain.

  Ballistic steel construction increases hardness and durability for repeated use on harder-wearing ice, mixed routes, and dry tooling.

• Forged Steel: Not as durable as the Katana Ballistic steel, but still very durable and ideal for normal use on pure ice.
