I have personally lost two pivot heel pieces due to the steel ring snapping, and have heard several stories from friends about the exact same piece breaking and then getting into nasty falls because of it. The brakes remain on the ski but the entire rotating part just falls off.
How has this not been addressed by the company yet? Will they not have a large lawsuit on their hands if someone blows a heelpiece in a technical line and fucking dies? It seems wrong to me that they continue to sell bindings that randomly explode.
