What the model says

Carve radius, to scale

  • Sidecut radius: 20.16299687825182 m (est.)
  • Carve radius at 30° edge: 17.5 m
  • Carve radius at 45° edge: 14.3 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: 11%, 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 Stone White Marble 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 (8%)
  • Beginner: sinks (9%)
  • Intermediate: sinks (9%), assumed level
  • Advanced: sinks (10%)
  • Expert: sinks (11%)
assumed intermediate: sinks (9%)

Ease

How forgiving it is
  • First-timer: hard (0%)
  • Beginner: hard (21%)
  • Intermediate: manageable (75%), assumed level
  • Advanced: easy (100%)
  • Expert: easy (100%)
assumed intermediate: manageable (75%)

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.

Who it suits

It suits

None of the three skiers we check puts it in the top half of the catalogue.

    • Strongest here: edge hold. Weakest: float.

    Maker's descriptionAll models are the result of cutting-edge sandwich technology with ash/poplar and titanal material. The latest model captivates with its unique design, which turns each ski into a unique object. Efficiency, robustness, and simple beauty characterize the ski. Its true size becomes evident, particularly on hard slopes. zai transmission system: the particularly developed zai system combining ski geometry, preload, and positioning of the binding optimizes the force transmission, and thus speed and control.

    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).
