I just bought a new 11 speed Shimano chain online. The wide end of the chain had a flat pin half sticking in, I tried to use a chain tool to release it a bit allowing for more room to connect the other end of the chain. Instead I accidentally removed it completely.
Now I can't get it back in like the other chain connectors. Do I need a Shimano chain Connector or is there another way to do it?
Can I just get some of the left over chain and add it to the other end getting rid of the part with the pin I knocked out or is it required?
