How to stop a clicking seatpost
I have had this click once every pedal revolution that drove me mad for a while. After a lot of puzzling, I am 90% sure that it is actually the seatpost tapping the inside of the tube. I deduced this based on the fact that I can't make the noise when I am standing or off the bike. I feel better knowing what it is, and that it's not serious, but it is still kind of annoying. Any tips on how to stop the clicking sound? I've tried shimming the seatpost with random stuff but the clearance is so tight at the collar that it inevitably just scrapes it off or jams.

Light grease on the post and clamp bolt threads has cured this problem for me in the past.

I had one like that. It turned out to be the saddle rails where they enter a plastic block at the front of the seat. Silicone spray fixed it.

Use Carbon Assembly Compound on both the post and the rails, and tighten with a torque wrench within the manufacturer's specified range. Do this whether any of it is carbon-fiber or not; that doesn't matter. Unless something's cracked, your problem will be solved.

I went through this troubleshooting process a few months ago and it turned out to be the seat collar. I think the screw may have been over tightened and bent a bit on the original collar. Long story short, it was a cheap fix that you should keep in mind if the other suggestions don't pan out.
