Chainring just don't know when to let go 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.
This is called chain suck. One possible reason is worn chainrings.

In the question it is mentioned that the rings were used with worn out chain. This wears out chainrings quickly.
