anyone getting creaks from their fik/fin ring to chain interface?

I have an annoying creak when pressuring the pedals, it feels a bit grunchy too. I note the black anodising is worn off the thin teeth of the ring.

I can’t be sure it’s the ring (Works Components with a KMC chain), however I have eliminated:
* BB
* pedals
* cranks
* derailleur
* cassette
* skewer
* <edit>chainring bolts</edit>
out else? rear hub? (it feels ok)

Crank bolts might be loose

Chainring bolts I mean

no I checked that, I missed that off my eliminated list

but ta for the heads up

What bike is it , my mate had the same issue on his orange 5 , and it. Actually turned out to be his rear wheel , his 10 mm bolt thru had worn so much , he replaced it and the noise stopped .

I’ll look at the dropouts, ta.
