Carbon seatpost - grease or not
Comments

The smart money nowdays goes on a carbon assembly paste, such as those by Tacx or Ritchey. Not only prevents seizing but forms a gentle bond which means you get away with less torque on the clamp bolt.0

Yep, I am using The Ritchey one on a carbon seat post in an alloy frame. No problems as yet but I do remove the seat post every month just to make sure things are not bonding. I use 5Nm torque.0

Sounds good SJ. Although I'm sure that in the next few blogs someone will tell me
something completely different. Think I'll just go back to aluminum. I have a carbon post that I grease on a regular basis and have yet to have any problems, including slippage,
and I'm sure it's torqued down probably beyond it's spec's(I like things tight).

Hi there.
What you don't want to do is to leave it in there untouched for 2 years, then when you're packing your bike the night before flying off to the biggest race you've ever done and find the f****r is seized.
Even worse you then realise that as it's an aero seatpost that it's not round, hence the usual technique of twisting the saddle to unstick the thing doesn't work, cos it doesn't twist.
Not that I'd be stupid enough to do that...

Me neither. Then again I'm not so smart as I thought I was. Just lost an arguement, or
maybe I should call it a debate, with "aracer" about spoke angles on the rear wheel.
It wasn't pretty.

Grease can cause carbon to swell. Use either nothing or the carbon jointing compound mentioned above.0

The carbon is protected by a lacquer, after all.0 -

As a slightyl OT aside, this assembly paste is a good bodge if you have a frame with a slightly loose seat-tube/ seatpost interface, whatever the material. My post always used to slip on my cross bike, but since using the tackx paste it never moves (unless I want it to. Seems to stop seizure as well as grease).
My understanding was that it didn't make a bond, but actually created more friction due to having lots os tiny squishy microscopic balls in it. I can't remember where I read that though.0 -

Being generous, I'd say that wasn't a fair fight. ;-)

I'd also point out that it was more that I was trying to educate you than anything else - I mean it's not exactly as if you were telling me I was wrong, just that you weren't getting the point I was trying to make!0
