How to Prevent Chatter
One of the most effective ways to prevent chatter in a more completed or closed turn is to change onto the down hill edge early. By having the edge change at the top of the turn, the rider can manage the edge pressure, dispersing it throughout the whole turn instead of letting it build up at the bottom, which results in chatter.
Because chatter typically happens on the heel edge, focus on the transition from toeside to heelside. Using a blend of flexing, extending, and rotational movements, you can change onto the new edge while it’s oriented across the fall line, blending the finish of the toeside turn into the initiation of the heelside turn, sometimes referred to as the “finishiation” of the turn.
There are a variety of movement patterns to accomplish the flattening of the board to change edges, but the key is moving the center of mass (CM) toward the heel edge. One caveat to this is that the board should be traveling in the direction it’s pointing (across the hill, in this case) in order to not catch a downhill edge.
How to Fix/Manage Chatter - Coaching Cues
Chatter happens – especially on steeper terrain when edge angles tend to be higher and more pressure builds on the board. There are two options to reduce chatter while it is happening. (Okay, three if you count sitting down.)
1. Lower the edge angle and let the board slide the way you’ve originally directed it. Do this by flexing the knees and dropping the CM downward to release the edge and/or opening both ankle joints to reduce edge angle.
2. Actively direct the board’s travel across the hill, leaving the body in an aft position over the tail. Using fore and aft movements of the lower body helps drive the board along its edge as designed. This also reduces the pressure building up against the edge.
Preventing and managing heelside chatter is all about pressure management. Reduce the amount of unnecessary pressure that can build up at the bottom of the turn and let the board do what it’s designed to do.
