My chain needed to be replaced for half a year ago and I've finally replaced it. But after replacing it, I've notice a lot of clicking noise from the chainring area. and when I go check it, I saw the chain sticking to the bottom side of the chainring while I'm pedaling.
I went back to the shop to tell the owner what's wrong, he just say it's the friction from the chain and the chainring, it will be gone if I just ride the bike for a month or so. Now the noise is still there but not as loud as before, but is there something I should have done that doesn't require to wear off the bike chainring? Cuz I bought the chainring a few months ago.
Update: my old chain needs to be replaced but I kept on using it for almost a year already, not sure if that's the reason why.
Here is a pic of the chainring.
