Grivel G20 Plus Cramp O Matic

G20 Plus



My vote: None ( 5.7 avg )


A well-known system which relies on a nylon speed lever in the rear and a stainless steel front bale to hold the boot. Quick to put on, these bindings are perfect for plastic mountaineering boots that have a rigid sole and substantial heel and toe welts. The stainless steel safety strap, which was invented by Grivel, is permanently mounted on the front bale and prevents total loss of the crampon should it be forced off the boot.

  • The lightest technical crampon in the world.
  • Replaceable hot drop-forged front point.
  • New central points to improve the stability while descending.

The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.

To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.

Rock and Ice Gear Review no rating given just a review

As for the front bail I’ve used them with three different types of ice and alpine boots, and had no problem with fit. Always, the bail slides right in. As a rock climber, I appreciated the asymetrical shape and position of the front point over (roughly) the big toe. This positioning gives power to your front toe and feels natural. Because the front point only has a small accompanying point—a horizontal and much shorter mini-point—the main point is able to dig deep into seams and picked out placements. Forgot your crampon bag? No problem. Fold the G20 Plus in half.

WeighMyRack Gear Review first-hand review

Overall the precision front point allows the G20 Plus’s to feel like an extension of the boot and your thoughts. Most of the time it takes only one fluid kick and each foot becomes a stable platform that instills confidence even when the ice is shattery. While climbing, these crampons melt away from my consciousness and allow me to focus on everything else, conserving energy, placing appropriate gear, and enjoying myself. I don’t think there is much more you can ask from a piece of gear.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
