What the model says

Carve radius, to scale

  • Sidecut radius: 12.69156809043762 m (est.)
  • Carve radius at 30° edge: 11 m
  • Carve radius at 45° edge: 9 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 165 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 Kästle RX12 SL FACTORY FIS at 165 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, 165 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 (0%)
  • Intermediate: hard (32%), assumed level
  • Advanced: easy (82%)
  • Expert: easy (100%)
assumed intermediate: hard (32%)

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
