I don't know how it happened or when but my top sheet cracked and heaved heelside behind the rear binding. (I ride normal) I don't ride extreme or do anything crazy in the park? Is it ok to ride or am I asking for trouble? Anything I can do to fix it?
That looks a little worse than a topsheet crack to me. I've got tons of spidercracks on my topsheet from it flexing, but none of them are structural. Was there no impact you remember? Is the board still under warranty?
