G Zero

Rating

My vote: None ( 4.9 avg )

Description

G-Zero is a very light ice axe for classical alpinism that still has all the characteristics of a Grivel ice axe, one piece head that provides maximum strength and minimal weight. The pick is Classical neutral with ergonomic design that remains comfortable after hours and hours of climbing. The brand new insulating removable ergonomic blade cover, lets the user firmly grip the axe by the head without risk of injury, it also protects the hand from contact with cold metal especially in low temperatures and high altitudes expeditions. The perfect tool to discover the mountains with added safety and comfort.

Weight (g / oz)

Weight (g / oz)

In grams and ounces, the weight, as stated by the manufacturer/brand.

Since the most common ice axe length is 50cm that is the main length that we reference.

When available, we list the weight for each length here.

425 g / 15.00 oz

The manufacturer only lists weight of 66 cm axe, which is what we’ve listed. We’re working on finding the weights for the other sizes.

Best Use

Best Use

Ultralight Mountaineering

The lightest axes available, used most for ski mountaineering, adventure racing, and other "go light" ascents. 350 grams is usually the max weight. The decreased weight means they are axes are built for snow missions, not ice.

Mountaineering

This is the most common type of snow mountaineering axe. These axes are above 350 grams and are a great balance of weight and durability. There may be a grip and they will always have an adze head (and no matching hammer pair). These axes are great for snow and can handle chopping steps in ice, or other small ice scenarios.

Technical Mountaineering

These axes are for tougher conditions when the majority of climbing is on snow, but the axe needs to be able to handle a short ice wall. They generally have a bent shaft and T-rated (more technical) pick. Often these beefier axes will have a rubberized grip and they may have a matching adze and hammer version. They're basically the offspring of an ice axe and ice tool.

Length Options (cm)

Length Options (cm)

Measured in centimeters, the best length is based on your height and ape index (arm length). Holding the axe in your hand, the spike (sharp end) of the axe should arrive around your shin. At the max size, it should go to your ankle.

Two people of the same height could need a different sized axe, based on arm length (t-rex vs monkey). If in-between sizes, our bias is towards sizing shorter.

Rule of Thumb

  • Under 5'6" 50cm
  • 5'6" to 5'8" 50-55cm
  • 5'9" to 6'0" 50-60cm
  • 6'1" to 6'4" 55-65cm
  • Over 6'4" 60-70cm

Worth Considering

There are other resources online that suggest a longer axe is a plus and that you should measure below the ankle. We absolutely disagree. A longer axe means you'll be tempted to use it as a trekking pole (which will put you off balance), or you'll have to give your arm a huge workout just to lift it in and out of the snow. Ice axes are meant to be used on the uphill side, which is already much higher.

Head Details

Head Details

This refers to the back of the ice axe head (opposite the pick).

For ice axes, adze's are (by far) the most common. An adze will allow you to break ice by chopping or shoveling in a specific area, and they also provide more room to hold on to the head than a hammer does. This grip helps for arresting too.

Hammers are usually only used as a pair with an adze on the other axe (hammer's are much more common in ice tools than ice axes). A hammer uses a more broad force to break ice bulges.

Certification

Certifications

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.

For ice axes, there is a separate certification for the pick and the shaft.

This isn't super common, but sometimes the manufacturers will state a specific warranty such as "3 years against manufacturer defects"

I’ve used it a bunch

I bought the Grivel G-Zero for classic lower-48 mountaineering routes.  I've climbed with it in snowy Colorado couloirs, and on exposed glacial slopes high in the cascades.

 It's light weight makes it perfect for the weight-conscious mountaineer, offering great balance and outstanding self-arrest.  I've also used it to belay a partner in a t-slot when I didn't have any picketts.  Held up great!  Overall it is an outstanding mountaineering axe.  I gave it 4/5 stars because it's straight shaft makes it difficult to climb technical routes, so I had to opt for a hybrid axe and technical tool for those routes.  But if all you plan on is steep snow, this is the axe for you!!
