I have a felt s22 coming in a couple of days. It has a carbon seat post. How many foot pounds is that to be tightened to?
just do what feels right in your heart, that’s the best advice anyone can give
.
It will be in the owners manual.
Tighten it until you hear cracking and snapping noises, then back it off a little bit.

use even and equal torque on both bolts and tighten to 5Nm. Do not exceed this value and be sure to equalize the gap between the frame and the seat post clamp on both sides of the clamp itself. Use lube on the shoulder surfaces of the bolt and the threads, but not on the clamp itself or inside the frame.
If you trim the post, be sure to leave >87mm inserted below the surface of the clamp where the post enters the frame itself.

Why no lube inside the seat tube? My '07 B2 was having a horrible squeaking noise that was coming from either the saddle clamping mechanism or the seatpost. My LBS ended up putting some lube inside the seat tube. I asked them if that was a good idea as everything I ever heard was “DO NOT LUBE INSIDE CARBON FRAMES OR CARBON SEATPOSTS.” I was told not to worry. End of story. No more annoying squeaking with every pedal stroke. So did my LBS do anything wrong here?

The symptom you descibe is not typical and typically is the result of the saddle clamp of the seatpost moving slightly, not the post in the frame. Nonetheless, applying lube to the post itself reduces the friction to an extent that the seat post clamp itself may not hold the post in place w/o overtightening the clamp itself. In your case, it sounds like you haven’t had any problems, in fact, the lube may have solved one. It will not affect the integrity of the post or the frame provided the torque settings are adhered to.
