Bike noise, creak, click, creaks, clicks, clicking, pinging sound - help

before you grab the chain tool and get stuck in an endless loop pushing the pin a bit too far each way never loosening the thing up. Just grab the chain either side of the stiff link and flex it back and forth a few times, dont be gentle. That will more than likely sort it out. Unless of course you can see that the pin is badly positioned.

good point!
