I bought a Trek X-Caliber 9, September last year.
About a month ago it started to do a very annoying sound between the welded junction of the Seat Tube and the Top Tube.
What I have tried:
- Switch the seat post and saddle.
- Switch the pedals.
I cannot ride with these noises they truly disrupt my mind.
The creaking only shows up when I sit on the saddle, I replaced the saddle and the seat post but the creaking didn't cease. I think the noise is from that area because I've put my hand in there and felt the creaking.
I have cleaned it several times and even if I lower the seat post the creaking continues.
UPDATE: I still have the issue, I am going to the second Bicycle Repair Shop this weekend, But I think it is the left arm crank who's making those noises. But I will keep you updated! 2021-04-23
