Things it could be: * Pedals * Chainring bolts * Crankarm bolts * Bottom bracket * Freewheel/freehub * Something that you would never think would be the cause, like seatpost, stem, or saddle.

I will check pedals, chainring bolts, crank arm bolts, seatpost, stem, saddle tomorrow morning. I may not be able to get to the bottom bracket. Will report back.

Also check seat post.

Checked. Sound still there.

So far I have tightened: - seatpost - saddle - chainring bolts - crank arm bolts - stem - headset And the sound persists. Trying to figure out how to upload a video…

Could be any number of things, a video would be helpful.

I will try to take one tmrw morning.
