In a recent VeloNews article, Craig Calfee
recommends the use of grease on seatposts
used in Calfee frames. On my carbon post,
Campagnolo discourages the use of grease.
Anybody out there greasing their seatposts
in their Calfees?

I wonder if grease is OK with the bamboo frame?

Rod: I would follow the recommendations of Campy. I never used grease on any of my carbon seatposts and had zero slippage problems when I planted my a** on the bikes.

Um, that is not how Craig is quoted in the article. That is how misinformation gets started!
For years, I've been telling people that Craig told me specifically not to grease my Aluminum seat post, which is what he said when I mentioned to him that my post was slipping.
Reading the article sheds further information that he didn't say to me. "If the seatpost fits tight, grease it. If it slips, de-grease it." I fell into the second category and repeated it as gospel from the Jedi Master as all encompassing information regarding his frames.
I apologize to those I mislead. ...assuming of course that Craig was quoted accurately!

Grease your seatpost only if you are having trouble taking it out or getting it in. As far as the bamboo bike is concerned, we use the same seattube insert that we use on all our frames, so seatpost grease techniques are the same.

Alright people, understand this: it is the galvanic reaction of dissimilar materials that grease alevieates. Aluminum should never touch steel nor carbon fiber. A very light coat of grease will prevent the freezing of the seatpost in the seatube. Note that Craig said why he uses fiberglass, since no galvanic reaction occurrs between fiberglass and carbon fiber. Another issue to be very careful of is to never get grease on the threads of the seat clamp. I suggest a de-greaser be used with an old toothbrush to clean the clamp screw and a cotton swab with degreaser on it to clean out the threaded hole. Also use proper torque on seat post clamps based on manufacturers reccommendations except when you are sure the manufacturer speaks with forked tongue. With a carbon post in a carbon frame, keeping both inside of tube and post sparkling clean is important. The slightest bit of dust or grease will cause some slippage problem.

Why?
My ignorance stems from the fact that I grew up in the school that teaches one to grease EVERYTHING unless there is a darn good reason not to.
Actually, I disagree with Craig regarding not greasing seat post, but I follow his advice because:
1. My seatpost slips if I grease it.
2. I do not have any problems with galvanic reactions.
3. I can still move it when neccessary. (traveling etc.)

Assuming you can obtain correct torque values, how can you possibly torque to that value accurately without grease (or anti-seize) on the threads? There will be too much friction on the threads and that will give false readings on your torque wrench, particularily with the relatively small threads used on a bicycle.

Skuke,
How is this misinformation? Craig Calfee is
quoted as saying:
"I don't know where the myth started, but
carbon composites are not affected by grease."
The link is provided for the entire article.

The honorable Stella told me to degrease my seatpost and seattube with alchohol before installing.I would do anything Stella told me to do.

Cinelli,
You said "Craig Calfee recommends the use of grease on seatposts used in Calfee frames." That is not entirely accurate. It is only an accurate statement if your seat post is too tight and sticks. If it is loose, Craig says NOT to use grease, per the article.
With your quote, it could be interpreted as a "blanket statement" and that is not what Craig intended. That misinterpretation and incompleteness of his quote is what I was referring to when I said that is how misinformation starts.

Skuke,
Again, please read the whole article.
The article addresses the issue of using
grease on carbon seatposts. Specifically,
the original question to Lennard Zinn was
concerning the use of grease to prevent
carbon seatposts from sticking. Craig
Calfee adressed this by clearly stating
that grease does not harm carbon composites.
You can look at this as a "glass half full/half empty"
debate. My point, and the point that both Zinn
and Calfee make is that grease does not harm
carbon seatposts. Whether the seapost slips is
another matter that needs to be addressed. But the
original point that I was making is that Calfee
says grease does not harm carbon seatposts and
can be beneficial in preventing seized carbon
seatposts.

Cinelli,
You clearly state that "In a recent VeloNews article, Craig Calfee recommends the use of grease on seatposts
used in Calfee frames" ....Skuke is correct. That is misleading. That's different than saying grease doesn't harm carbon or alleviates seizing. In reading the entire article, he recommends grease if your post is seizing, no grease if your post is slipping.

No worries. I just wanna clarify what Craig said and stop rumors before they become gospel.
Calfee + Grease = Good & Bad and sometime even Ugly.

The important thing is did you buy/order/find/secure a frame yet?

My new (to me) Tetra Pro arrived Thursday.
It is nude with new decals. I am sending it
to have a clear-coat applied before I build
it up. Now, if I could just find another
60cm Tetra or Dragonfly to keep the first
Calfee company!

There is NO WAY on this earth I could have a frame like that in hand and send it for service without riding it first.I would build it up,ride it once or twice,strip it and ship it.You have the patience of a saint.

I just got my new Tetra frame on Wednesday morning. I put the Record group on, got everything adjusted & went for a ride that night. There turned out to be a "finish" problem that I wanted to get fixed, so I stripped the bike on Thursday morning & had it shipped back to Calfee to get it fixed. I was told that I should have it back next week. I wish that I would have realized the problem before I built up the bike though, then I wouldn't have known what I am missing!!! My Calfee is the greatest ride that I have ever had - much stiffer than the Litespeed Vortex that it replaced. I just wish that I would have gotten a Calfee sooner - I have been riding ti for the last 10 years! I can't wait for the January crits.....

Crits in January in RENO??? Do you put your bikes on skis or something  You were joking, no?
If we had crits up here in Oregon in January, I'd have to turn my bike into a floatplane. All rain, all the time.

Not in Reno. I will be putting chains on the car so I can drive to the Bay Area for the "early bird crits". They start the first weekend in January. I am really looking forward to the stage race that's in Las Vegas at the end of January - that should be really fun! It is possible to ride throughout the winter here though - my coldest ride last year was 9 degrees. My toes got cold.

I think you will be completely tickled with the way your Tetra Pro performs. I "merely" have Luna Pro and couldn't be happier with the way it handles. Absolutely dead on steering in my experience. Lean all you want. Accelerate hard. Everyone will be sick of my rap by now, so I won't give you the full enormity, but I rode it in crits for the first time last summer and I was really pleased.
Please, send us all a report so we know how things went. Ditto, Vegas.

back to the subject of grease and seat post fit.
I'm putting together my new Luna Pro and the Carbon Chorus Seatpost is EXTREMELY tight. the only way I managed to get the seatpost in at all was to grease it and pound it in with a rubber mallet. The collar is comletely loose and the seatpost is jamed in there tighter than a @#*%. Am I missing something?
Also, what's the deal with the third cable guide/boss in the middle of the top tube and why is it not lined up with the other two?
Thanks for any info you can provide!
