Was out today and had a double whammy. First I flated near the start of ride then near end of ride my chain came off. At first I thought it was the quick link had came apart but one of the links had came off, I actually found the offending link. Didn't look to be damaged at all just inside plate came off, the chain was not wore out but did have close to 5000k on it, oh well guess it was time for a new chain.
