Breaking chain link on some random place
My chain was so dirty that I haven't noticed that there is the master link so I used the old tool I had to remove one pin. After cleaning it, I returned the same pin back in.
The chain is KMC x11 placed on the e-bike and now after some YT videos, I realized that I shouldn't use an old pin.
What are the experiences here regarding this? Should I remove that part and put one more master link?
