Grease carbon seatpost?

Theres a special lube for carbon parts.

Dear Rick,

Probably poor Tom's a-cold, saw the danger in
the other post, and fled here to defy the foul
fiend.

Actually, it was Jim Beam who pointed out that
some greases can affect the resin over time,
but I swell with pride to be cited where I have
no business.

Orgulously,

Carl Fogel

Dear Tom,

Below are a few quotes about carbon-fiber parts and grease.
The galvanic reaction one sounds dubious--the rest suggest
that carbon-fiber doesn't corrode onto metal and that grease
might make things too slippery and lead to over-tightening.

Jim Beam has suggested that some greases can do bad things
to the resin (presumably gluing, corroding, or swelling).

It's hard to see any purpose for a special grease, since
the carbon isn't likely to bond to the metal.

Carl Fogel

Use grease only if needed for lubrication; carbon posts
are slippery and will not cold weld to any frame material.

As with any fine bicycle, grease the insides and faces
of the head tube where the cups go in, and the crown
race seat. Grease acts as an insulator against galvanic
reaction betwen the carbon frame and aluminum head
cups.

Make sure the seat tube is free of grease. Grease is
not necessary for this seat post, in fact it may cause
slippage.

The seatpost shim provided with the frame helps
distribute stress underneath the clamp. Additionally,
it improves the slide fit of the seatpost and reduces
the possibility of dirt entering the seat tube. It is
supplied pre-installed and pre-greased but the
carbon post should NOT be greased and the
aluminum post should be greased before inserting
it into the frame. The shim is held in place by the
seatpost collar so one should be careful when
loosening the clamp. IMPORTANT: There should
be no grease between the carbon post and the
brass shim.

When inserting the seat post into the seat tube,
do not apply grease to the carbon quill. You should
also clean any grease out of the seat tube. Because
carbon does not tend to freeze and lock into the seat
tube like aluminum and steel posts, grease is not
necessary. In fact, applying grease to a carbon seat
post might force you to overtighten the seat tube
clamp in an effort to prevent the seat post from
slipping. Finally, when you insert the post into
the seat tube, do not use a rotating motion. This
can scratch the seat post quill.

Thanks, Carl, What about a dry lubricant? such as
graphite? -tom

check what the manufacturer says! easton say /not/ to
grease. the reasons have already been covered in this
thread.

Dear Ml,

Here on rec.bicycles.tech, due to a wider range of better
informed practical opinions and engineers known for
working out theoretical problems without rancor, the ratio
will probably go to 50/50 yes-no-maybe.

If the frameset is carbon, no- if it is anything else-yes.
We just had to cut an Alien out of a aluminum frameset that
was dry as a bone.

I'm thinking any lube will eventually absorb into the
carbon, which may cause swelling and why the instructions
says to not grease. Also I believe the H20 (grime and grit)
from riding in the rain could be enough to seize a carbon
post. I haven't fit it in yet, think I may return it and
stick with my old faithful, tried and true Campy Super
Record Alu post. -tom

Good tastes Peter. When I was in Jr. High School, I saved
part of my paper route money to buy a coffee brown Italvega
Super Prestige with all Campagnolo Record components. For
eight months, I rode my beat-up Schwinn cruiser bike to the
famous Desmonie's Bike Shop on 2nd St. in downtown San Jose
every week, to make lay-away payments of $10.00. Able, the
owner wrote me a hand written receipt with the balance due,
while he talked about his racing days in Europe. He knew I
was only half listening as I would just stare at the bike I
would soon have, then he would yell out; "Hey kid, you can
stop drooling now!"

Now days, money isn't as tight, but I think I treasured
things more when I had to save for it. Good luck with that
new Merckx! -tom

A well made aluminum post sure does a good job of being
a place to put the saddle. My new Merckx has a Record
