Just lie to them, tell them it broke when you landed on it if it actually broke cuz of rails, they're not going to cover damages from grinding rails. If theres damages to sidecuts from rails, suggest ya tune it up before sending it in, so they dont get suspicous or anything like that.
Jesus said, 'Lucky is the lion that the human will eat, so the lion
becomes human. And foul is the human that the lion will eat, and
the lion still will become a human.'
