Creaking seat, maybe seatpost - to grease or not to grease?

[hab1966]

Have some creaks from the seat area. Ive cleaned and tightened what i can. Should i be applying grease to the seat rails and seat post?

[Tony1963]

When I had that issue, I smeared the seat post with some grease and the issue disappeared.
But… it was a grippy type of grease that I can’t remember the name of! I’ll keep thinking

Edit: carbon assembly paste.

Carbon.
Try some pencil lead ground, its very good for sticky locks.
I usually just colour the key in so to speak, works well and almost free. Try colouring in the seat post? Hth.

Are you sure it's not your bottom creaking?

One of the YouTube cycling channels had this issue on a Chinese carbon bike he was building.

He eventually solved the problem by wrapping where the seat post fitted into the frame with tinfoil. It’s certainly an easy and cheap trick to try, even if it doesn’t work.

Yes
Take it out and give it all a clean

If it's a carbon post, put some carbon gripper on it and re-assemble
If it's aluminium then grease it up and put it back together.

It's propoably the saddle rails and where they fix into the saddle.
I spent ages trying to locate a creak on my bike, BB out, cranks all apart, everything regreased, etc.
It was the saddle rails!
WD40 in the fitting holes and it cured it for a couple of weeks.
Swapped the saddle, not an issue since.

It was the seat rails on my saddle that was causing a squeak. Put a bit of electrical tape on the rails where it clamps and all good since.
