i can't get a clear picture of what happened in my mind... would you happen to have a picture of said break?
having said that, the fork isn't exactly a quality fork. it's rigid at the best of times, and it weigh a LOT. this kind of break however, shouldn't have occured unless your son cases a lot. i rode my Gila T5 for over a year before i replaced it, never had any problems with the fork besides the fact that it never worked to begin with.
