Product description

The Grivel Helix SPD Ice Screw has an integrated sling that allows you to climb quicker and with a lighter load. This makes protecting your pitch easier and faster, reduces the chances of dropping gear, and saves you the weight of a carabiner on every single piece. Unlike most ice screws, all of Grivel's screws have reversed threads
that increase their resistance against extraction for superior strength
that you'll appreciate when you're on the verge of falling. Like the standard Helix ice screw, the Grivel SPD includes a large knob that makes placements easier, even in the hardest bulletproof ice.

  • Symmetrical grip
  • Large knob on grip
  • Reversed thread design

Welche Bruchlast hat diese Eisschraube?

Hallo,

sämtliche Grivel-Eisschrauben werden bis 10 kN getestet - diesen Test müssen sie bestehen, weiter wird hier bzgl. Bruchlast "Laborwert" nicht getestet.

Grundsätzlich spielen bei Eisschrauben andere Faktoren eine wesentlich größere Rolle. Die Beschaffenheit und Temperatur des Eises, die Art, wie die Eisschraube gesetzt ist und in welchem Winkel sowie die Außentemperatur (kann die Eisschraube freischmelzen?). Eine gut gesetzte Eisschraube in gutem Eis kann wesentlich höhere Bruchwerte aufweisen als ein Bohrhaken im Fels.

Viele Grüße von den Bergfreunden,
Janpeter
