Hi guys, I've been noticing some small noises from what I thought were coming from the bottom bracket, but as you can see from the video, it may actually be the crank. It just seems hard to explain how it could make such a noise under no load when it only happens on the bike if I put a bit more watts (not that I have that many though). Feedback greatly appreciated.
Ride safe.
What could be the reason for this strange noise coming from the crank?

Try regreasing your chainring bolts and then torque them to spec
Does it make the noise if you move it like that when its teeth are not touching anything?
These four bolts are probably loose.
It’s the pedal.
Could be the cover to the chainrings. But perhaps more importantly, wtf kind of test is this? Maybe just don’t do that since you said in another reply that the sounds doesn’t happen when the teeth aren’t touching the surface
I am going with someone standing behind the camera and smacking something to make that noise. (Kidding of course.)
I’d bet it’s pedal related.
Are all the pins, embedded to assist with moving chain, still firm in place? Almost sounds like one could have disbonded or something
Also leave it to r/bikewrench to have a post ‘why doesn’t my crank roll on the counter right?’
What are those rivet things on the big ring? Maybe a potential source? Edit: seems like another commenter identified them as pins
I’m pretty sure it’s the sprocket rotating on the table top. Caused by the elevation of the pedal.
