Would the teeth on my chain ring and casette be considered worn. Recently my derailleur broke when I put some explossive pressure on my pedals (the chain was bout 2/3 down the cassete) and the the derailleur cage was pulled appart with thr inner cage’s threads being destroyed. This happened to me before but I thought it might have been that something wasnt tightened properly. So when this happened aagain I was furious.
