What the model says

Carve radius, to scale

  • Sidecut radius: 16 m
  • Carve radius at 30° edge: 13.9 m
  • Carve radius at 45° edge: 11.3 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 176 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 Disruptor Black at 176 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, 176 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 (24%)
  • Intermediate: manageable (77%), assumed level
  • Advanced: easy (100%)
  • Expert: easy (100%)
assumed intermediate: manageable (77%)

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

  • 70 kg, intermediate, on groomers456 of 1009 skis in the catalogue for this skier.

Maker's descriptionModels 151 and 158 cm are designed with a supple core, agile and playful. The lengths 164 and 170 cm unfold a medium hardness in the core area – agile and with a good grip. The 176 cm is considered as the harder and thus race-oriented ski – here we use, apart from a solid wood core, also thicker titanal. All models are the result of cutting-edge sandwich technology with natural rubber, ash/poplar and titanal materials.
