What happens if my skis become "edge high?"
Do you ever wonder why you should have your skis tuned? Here are just a few answers:
- First of all, for optimum performance, the bases of your skis need to be flat. They should also have sharp, deburred and bevelled edges. This facilitates easier turn initiation. Although your shaped skis are designed for easy turning, they are often subject to a bit of abuse. The bases and bottom edges get worn down, and the bevelled edges of your skis become dull. This can result in either of two conditions: edge high and base high.
- Edge high skis are “afraid” to get off their edges. When you make the transition from one edge to the other, there is supposed to be a brief moment when both skis are flat on the ground. Edge high skis don't like this special moment. As a result, their turn initiation leaves much to be desired. Their behavior is erratic and “edgy,” so to speak.
- In contrast, base high skis are afraid to get up on edge. These “timid “skis prefer to skid through the snow, rather than allow themselves to experience the satisfaction of a good carve. The truth is, both base high and edge high skis are worn out and in need of a day at the “spa.” A ski tuning is a day at the spa for your skis.
- The ski tuning specialist begins by performing a base grind. This flattens the ski base, which in turn prevents the suction and friction that often impedes the smooth gliding experience. Once an appropriate base is established, the tuner grinds the edges in order to enhance their grip. Finally, in order to prevent oxidation, a coat of wax is applied.
