What the model says

Carve radius, to scale

  • Sidecut radius: 18.922499999999996 m (est.)
  • Carve radius at 30° edge: 16.4 m
  • Carve radius at 45° edge: 13.4 m
All three drawn on one scale, from the same starting point. A smaller arc is a tighter turn.

Edge hold and float

  • Edge hold: 100%, Holds well
  • Float: 21%, Sinks
Ticks mark where the word changes. For 90 kg at 174 cm: hold on groomed snow, float in powder. Model figures, not measurements.

These are the model’s numbers, not measurements. Carve radius comes from the sidecut, so it does not change with weight; edge hold and float do. Flex and camber are our estimates (see “What the model uses” below).

By ability

The Zai Onza at 174 cm for a 90 kg skier on groomed snow. Reviewers are mostly experts, so read the left of each band for what most skiers get.

Edge hold

On firm snow, 174 cm
  • First-timer: slides (19%)
  • Beginner: slides (41%)
  • Intermediate: on the limit (70%), assumed level
  • Advanced: holds well (95%)
  • Expert: holds well (100%)
assumed intermediate: on the limit (70%)

Float

In soft snow
  • First-timer: sinks (16%)
  • Beginner: sinks (17%)
  • Intermediate: sinks (18%), assumed level
  • Advanced: sinks (20%)
  • Expert: sinks (21%)
assumed intermediate: sinks (18%)

Ease

How forgiving it is
  • First-timer: hard (0%)
  • Beginner: hard (9%)
  • Intermediate: manageable (66%), assumed level
  • Advanced: easy (100%)
  • Expert: easy (100%)
assumed intermediate: manageable (66%)

Our model, run with working assumptions about how each level skis (edge angle, speed, how much weight reaches the edge). Not measurements. The marked cell assumes an intermediate skier; compare with your own details to see your own level.

      Construction
      CarbonFull carbon
      Maker's descriptionThe ski unites several cutting-edge technologies used by zai. Thus, the pressure transmitter made of spring steel was refined with zaiíra®, which stabilizes the ski in longitudinal and lateral direction. In combination with natural rubber, a new functional surface with a high technical performance evolved, creating a variational performance character. The inner life of the zai Onza hides numerous layers of unidirectional carbon fibres in different directions of travel. Two further absorbing layers from rubber were also inserted.

      Only what the maker prints. A field left out is one the maker does not state.

      Where these numbers come fromzai.ch, edgelab.ski, read 15 Oct 2026· “est.” marks ours

      Numbers come from the maker’s own pages, with the date we read them. “est.” marks a number the maker does not publish: ours. “from” marks a number the maker does not publish that another source does (a retailer, or an earlier season of the same ski).
