Cleat replacement depends on how often you ride and the conditions of the terrain. “Race mileage” riders may need to change their cleats as often as one or two times a year. A good rule of thumb is that cleats should be replaced when there is a change in the release/engagement effort. If the cleat begins to “float” more and releases at a greater angle, inspect the cleat for wear. Eventually, the vertical tab on the cleat that opens the retention mechanism becomes worn and greater effort will be required to disengage.
