I might be wrong but I've dropped the bike into first a coupe of times and locked the back wheel. I noticed that I had more than the usual play in the center hub. I think what might have happend was that the hub rode all the way up the ramp, further than was originally intended? I just bent the arms back on the spider spring and put it back together until I could get a new one. I still have it as a spare
