Yesterday, my chain dropped off the chainring and one of the links got bent sideways (didn't take a picture). This caused the chain to skip whenever this link would go over the casette.
I used pliers to bend it back into alignment. It's not skipping anymore, but I'm wondering if the chain link is compromised now and will fail under load (e.g. on an uphill, probably in the worst possible spot to get stranded).
I don't currently have a chain tool - should I buy one and remove the affected link? Should I replace the chain altogether (it's still new, only got ~600 km on it)? Or should I just keep riding?
