Gliding:
Diagnosis:
A damaged ski with scratches in the base has poor gliding capacities. Big holes in the base are affecting the turning capabilities and the stability. Bases that are grinded too rough or bumpy are slow. An uneven base causes a negative distribution of pressure and therefore bad gliding and turning.

Solution:
A correctly prepared ski is mended with P-Tex wire. The finish has to be free of fibers, planar with a fine structure. The ski should be regularly waxed so the base is nourished and protected against oxydation uv rays. Flatness means perfect gliding and turning.

Turning:

Diagnosis:
A concave or hollow ski from edge to edge produces uncontrollable edge grip and is gliding jerky. A convex or humpy ski base need an extreme angle for an effective edge grip and are very instable with increased speed.

Solution:
Planar ski bases allow controlled turning. An important supposition for a good Carving ski is a minimally tuned base edge (angle: about 0.5°) or even better a Radial Tuning (angle: 0.5° under the bindings and about 0.7° at front and end).
That makes turning easy and you get yet a very good grip on icy slopes.

Edge grip:

Diagnosis:

Different edge angles, rust, bumps and wear prevent a controlled edge exertion.

Solution:
The geometry of the edges has to be tuned with the snow conditions and the skiers technique. Usually we recommend an edge angle of less than 90°, especially for competition, aggressiv skiing and icy slopes and for carving skis.
