My XTR tossed the chain doing a river crossing..
Think a large rock pushed the chain side ways so it
could de-rail from the rear sprocket...
Thats all I can put it down to... chain was still tight once
I put it back on....
just put a few scuffs on the rear hub...
now the hub matches the rest of the bike...

They really should have a chain guide just in front
of the sprocket...
