This was on a 5% at about 240W
Rides and shifts fine
Getting out of saddle changes it a bit, doesn’t completely eliminate.
Checked spoke tension. Not 100% perfect but no obvious major problem
took off mech and checked hanger alignment
chain’s a bit old but should be ok
Pedals seem fine and secure. Pretty new.
BB is 6 months old. T47.
Jockey wheels the same
Thru axle is tight
haven’t checked the cassette is 100% tight but is also only 6 months old, installed by LBS.

Thanks. Don’t know how that q got in there! Fixed.

Does it creak if you are not seated?

A lot more than a creak. It sounds like chain-derailleur clearance issues. To me, it is hard to tell if it it is coming from that area. I think it would help to have it on stand.

Concur. Sounds like chain on derailleur to me.

You might be better off having someone ride next/behind/wherever to you with an open ear.

To me, it sounds like maybe a turn or ?? on a barrel adjuster might make a difference??

Give it 2-3 clicks each way and see if it makes a noticeable difference.

I can't really see, but are you on BIG:BIG?

IF it's not chain rubbing FD/twisted der., then remove the crank.. check for a trashed bearing. Could be pedal noise too.. the left side.
it sounds like a caged bearing that's on it's last leg... and i don't care how old the BB or pedal is.
the noise is more when you down-stroke on the left side.

T47... press fit, or threaded version?

SOME treks, and a few others, have had ugly noises from a PF BB walking around in the frames....look for powdery or dark gray buildup near the BB

once again.. check the left side more intensely.

another possible... big ring's teeth hitting the der, cage. Check yer clearance, Clarence. Left downstroke will rock the crank up on the right side......... proper is 2-3mm.. less than one is never fun.

I was on small / big or 2nd biggest. Big/big does scrape the cage on this bike, even when trimmed.

Put it up in the stand the day before and realigned the chain.

Makes no noise when running in the stand and doesn’t always when riding either. Comes and goes. Like I did the entire 60km ride in that morning with no sound and similar terrain / effort.

Definitely seems to change a lot when out of the saddle but doesn’t go away. It’s a Trek isospeed seatpost so there is a bit of give in that. I checked the saddle rails, seem solidly locked in.

will check clearance and bearings thanks
I thought T47 was always threaded?

Hmm. I wonder if this isospeed “servicing” on page 10 of this may be in order. Will give it a try.

hey, it's your bike... i rarely see those here in Podunk, Oregon.
the pressfit treks, and a few other brands, are known for sloppy/creaky BB behavior.
a bearing might be loose in a cup too.

it sure sounds like a der. cage rubbing on big ring teeth to me... as mentioned by delbiker too. the left downstroke fits that too, if you add a tiny bit of flex or a loose bearing....

What crankset do you have in there?
I just dealt with a similar sound, stemming from a Praxis Works M30 crankset. There wasn't enough grease on the NDS bearing/axle interface, and the creaking was INSANE.

I think maddog was right about the bearing. Drive side though. Feels awful. Maybe I didn’t replace it when I thought I did. This bike has hardly seen any water this winter….. oh hang on… there was that flooded road 3-4 months back where we actually had to fully pedal through it. I thought I’d got away with that and totally forgot about it until now, high clearance on a gravel bike & all that. Maybe the BB got a dunking after all.

I know this is a different derailleur…I copied it from the web. But did OP happen to have the chain off, and possibly routed the chain OVER the part of the cage the arrow is pointing to in the pic? There is usually one at both derailleur wheels. I’ve inadvertently done it a couple times. It makes a noise similar to the one in the OP video. — Dan

Your cassette have any wobble to it?

that IS the low point in the frame, you know... water collects at the lowest point...
.
glad ya found it.

Nah, done that before though, and on this bike too haha. A guy in a group I asked out on the road showed me a trick to remove the quicklink with a hex key using the chainring as a kind of anvil so I coild re-route it.
