| Re: Weird accident Another possiblility could be a protruding link pin on the chain which
might have caught on the derailleur cage.
I think that happened to me to cause my rear derailleur to trash into
the spokes. Twisted a thick steel dropout as if it were butter. I
was lucky the shop managed to bend back the dropout into position
without breaking it. I'm not going to re-use a used Shimano link pin
ever again. |
