I need advise to repair my chain.
Before 500 km I pit a new HG70 chain on the bike.
I broke the chain to take off some steps that the pin left in in one side.
Push it back but went more a little bit so the turning was not perfect. A little bit pushed back and was Ok.
From the side I pushed back came out the pin. (Probably what I set there.)
What to do?
1. Push it back again.
2. put a new pin what came with the chain.
3. change the step with 2 pins that can put together?
Left any more possibility else.
Thank for the advise.
