I cannot identify where this noise is coming from or what the cause of it is. Did a 70 mile ride the other week and this started with 10 miles left. Did 110 more miles with no noise. Started again the following weekend 10 mins in. Took it to local Trek dealer and they took out the BB and put it back in and could not identify. I’ve done 100 miles since and now it’s starting back up. This video is 25 miles into a 30 mile ride.
* I’ve taken apart the crankset and everything looked good
* Trek took apart the crankset and the BB and everything looked fine and they could not reproduce
* Did 100 more miles and it started back up
* Took the seat post off and cleaned it
* Tightened the seat
* Took water bottle cages off
* Put new pedals on
* Cannot reproduce on the bike stand
* Cannot reproduce while standing and riding

When you took apart the crankset, did you check to make sure the chainring bolts and rings were all tight? I’ve had some shimano cranks creak like that when bolts got loose.
Not sure if you’re on QR skewers or thru axles, but if you want to check the axles sitting in the dropouts, that could be a good start as well.

Grease the interface between your derailleur hanger and frame as another thing to try.

It’s always a case of elimination.
Does it do it when you’re standing up? Does it do it if you let go with both hands? Does it do it on both chainrings? Does it do it on all cogs on the rear cluster? Does it do it under braking?

Rear wheel, hub perhaps.

Have had the same noise come from my mountain bike. Thought it was the pivot bearings, replaced them all, greased all the moving parts, turned out to be the rear casette that was slightly loose.
Hope this helps

Just to be sure, did you use (carbon) assembly paste on the seatpost before putting it back in?
