Mine developed a horrific creak - turns out that one of the chainring bolts had snapped, think they are extremely soft.
Replace and retorque the bolt and see if that improves things?
Default for creaks is complete dissassembly and light touch of grease everywhere that parts meet, tends to be the cheapest and most successful outcome, even if it sometimes leaves me not knowing which bit was creaking!
same here, the creaking is crazy. I already replaced the chainring-Screws, cleaned everything and greased it. No changes.
I am pretty sure it is because of the size difference between the mount and the spider.
and imo the creaking comes either from
lockring and spider is "rubbing" or
spider and mount is "rubbing".
tried 2 different type of grease already.
I would say it is a little quieter than before, but tbh i'm slowly going crazy.
So it could be imagination.
btw: Geoid PM500 seems to have the same issue.
