Skis that are too soft for a skier’s weight or speed often suffer from vertical tip vibration. Conversely, very lightweight carbon-based skis can feel "twangy" and chatter more in firm conditions.
Failing to put enough pressure on the outside (downhill) ski is a primary culprit. If you lean too far into the turn (inclination) without enough downhill pressure, the light ski can't handle the force and begins to oscillate. Ski Chattering
Using an edge angle that is too steep for the slope's pitch can cause the ski to skip rather than slice through the snow. Skis that are too soft for a skier’s
Some high-performance skis include anti-vibration technology, such as the Völkl UVO3D , to absorb these oscillations before they affect the skier. How to Fix Ski Chatter If you lean too far into the turn
Wider skis (often 100mm+ underfoot) are designed for soft snow; when used on hardpack or ice, they provide less torsional stability and are prone to chattering.
Chatter is rarely caused by just one thing; it is typically a combination of technical errors and gear limitations.
