Carbon post? Maybe grease
July 11th, 2007 by Brad QuartuccioLast week I posted about the various reasons to heed manufacturer’s instructions and not grease carbon posts.
In the comments, it was pointed out that over at Velonews there is an excellent exchange between Craig Calfee and Lennard Zinn about why you should grease a carbon post.
Craig Calfee knows his stuff about carbon, having made bicycle frames from it since 1988. He’s the guy responsible for those bamboo and carbon frames that show up here and there in tradeshow and event coverage. If he’s saying that carbon posts should be greased, it’s settled.
Believe who you want.
Personally, being that I’ve never been terribly diligent about cleaning out my seattube of grease before putting a carbon post in, I’ve been running things with a very thin coating. You know, splitting the difference through laziness.

Brad, at the shop I work in, we don’t use grease on carbon seat posts. We use talcum, or baby powder!

Well, it WAS both Lennard Zinn AND Craig Calfee…who’s gonna argue with them?!?
I guess the bottom line is that one doesn’t HAVE to be afraid to use grease on a carbon post…I suppose folks should do what works for them (Tacx carbon assembly paste, grease, talcum powder, spit, banana peel oil, etc.). In any case, your original posting offered some food for thought, even if it may have perpetuated a “new” cycling myth.
Why grease when the carbon assembly paste gives you best of both worlds - avoiding corrosion while reducing the chances of slippage?
Here is a good article on how the carbon assembly paste works (besides Tacx Ritchey and FSA both distribute it).
