Quality carries this product and any shop can order it for you. The technicians at Specialized recommend this product for all installation of carbon components, but especially if the carbon is contacting aluminum.

Again, as stated in the subject line, we are talking about carbon on carbon, not carbon in aluminum.
Also, carbon fiber seat posts have no carbon touching the frame they fit into. It's the resin we are really concerned about reacting with grease.

Dear Lennard, Thankfully! An opportunity to dispel the myth that one shouldn't grease a carbon post!
I don't know where the myth started, but carbon composites are not affected by grease. Our advice is simple: If the seatpost fits tight, grease it. If it slips, de-grease it. As has been known for many years, when aluminum and carbon fiber contact each other, galvanic corrosion can start. That is why Calfee uses a fiberglass sleeve as a seat tube shim. Aluminum seat tube (or sleeve) and a carbon post will result in corrosion of the frame and possible seizure of the post within the frame. A carbon sleeve on an aluminum post will result in corrosion of the post. Salty environments accelerate this corrosion. Anodizing merely slows it down. About the only common chemical that will hurt carbon fiber is paint remover (which attacks the resin between the fibers). But there are many solvents that will dull a nice paint job. Craig Calfee

I have found a very light coat of grease actually helped keep the post in place.

Plus there’s always the possibility of a squeak, or more likely it’s a place to eliminate that union as the source of a squeak you can’t quite hunt down.

Use very light grease. No problem. If you do have a problem, Tacx, Ritchey and FSA make some sort of carbon “assembly paste” that should prevent slipping. Just be extra careful when tightening that seat clamp.

I originally only replied to the sender but on Dan's note:

The expoxy used in carbon composites are thermoset meaning they will not
melt and are generally quite chemical resistant. However they may be subject
to swelling (absorbing liquid). There are petroleum distillates and/or
solvents in many grease products which could cause this. Therefore it is a
bad idea to grease carbon parts with anything not specifically designed for
that application.

Run your posts dry or with carbon prep if they slip. Course sandpaper at the
clamp area is another good call.

If your post swells up in your frame have fun cutting it up into little
pieces to remove it... without cutting into your frame.

Good luck!

I have two bikes with "Alien" carbon post in them which I take out
(each) a couple of times a year when I pack the bike into a trico
box. Both have aluminum frame (at least at the top of the seat tube).
Never used grease, never had a problem except when the post was brand
new and under tightened. The older tube is now about 4 years old and
has a "slot bulge" at the tightening lug but does not seem in danger
of failure.

FWIW, Harbor Freight has a 1/4" drive torque wrench on their web site for
less than 30 bucks. They claim 4% +/- accuracy and 20 to 200 inch-pounds
torque range. That's well within the "typical" working range for most
bicycle work.

1/2" drive.... jeeez, I knew Zinn was tall but I didn't know he rode a bike
made out of water pipe. :)

Yea, Zinn also said in that article that you could use a 1/2" drive
torque wrench on your seat post clamp as long as you used adapters.

Yea, Zinn also said in that article that you could use a 1/2" drive
torque wrench on your seat post clamp as long as you used adapters.
IMHO that was a stupid piece of advice. There are no 1/2" torque
wrenches that have suitable settings and tolerances for the torque
required on such a delicate application. A large torque wrench is wildly
inaccurate at low (inch/lb) values - they are not all the same.
If you're going to use a torque wrench make sure it's working range is
proper for the required value.

My 2006 Giant bike had only about 500 miles on it when I bought it, and it
was almost impossible to remove the seat post. It had been over tightened
and the tube very slightly dented where the clamp leaves a "bite". However
even the undamaged round end of the tube was really tough to get to come
out. I greased it and it is still tough to move.

On the other hand, my titanium seat loves to come loose.

Didn't Leonard Zinn write about how you should remove your carbon
seatpost, inspect it, and regrease it once a year?

He said found cases where carbon seatposts would "freeze" in the frame
after being left in for an overly long time, and the only way to
remove the post was to destroy it (by very carefully dismembering it
with a hacksaw blade and removing it in chunks without scratching or
sawing into the frame).

Something about carbon and aluminum "bonding together" over time, maybe?

no grease and a torque wrench. If necessary use some emory cloth on the inside of the seat tube to eliminate two ultra smooth surfaces interfacing. I've had three carbon frames all using carbon posts and no slippage.

Friends,

New bike, carbon,
came with new carbon seat post.

I've not heard good things about carbon seat posts. The main complaint is
that they slip and I'd do better with a nice aluminum seat post.

Thoughts?

And um, anyone interested in a brand new Ritchey carbon road seat post?

Use very light grease. No problem. If you do have a problem, Tacx, Ritchey and FSA make some sort of carbon "assembly paste" that should prevent slipping. Just be extra careful when tightening that seat clamp.
