Campy Carbon seat post; to grease or not to grease?(11 posts)

Campy Carbon seat post; to grease or not to grease?tmguy

That is the question. I always grease before insertion, but not reccomended by Campy. Any advice? The frame is steel.

This question has been hotly debated many times here. First, grease will not melt, delaminate or otherwise harm carbon fiber. Even carbon fiber made by Campy. So there is no harm in putting some on. Second, people claim it will cause the post to slide into the frame. I can't see how a greased post would slide while an ungreased post would not.

However, if Campy tells you not to, then you probably don't need to.

I've used a Look Ergo post in both a carbon frame and a titanium frame with no ill effects. I grease the Colnago carbon post that goes into my C-40. Neither bike nor post has melted. I guess its just habit, but I don't think you can do any harm by doing this. I've had enough cases of bike parts bonding together that I grease everything.

I got a USE carbon post and they say specifically "NO GREASE!" I don't think seizure due to corrosion is an issue with these posts. If it's hard to get in and out, maybe try a little talcum.

I run an Easton carbon fibre post and do not grease it. It is fine without it. Plastic will not seize to metal.

Furthermore, grease will not really hurt it either unless you use some bizzare caustic "Do not use on plastics" grease.

Do it if you want, but it ain't necessary.

Cheers!

Conventional Wisdom says grease can actually weaken carbon. Mechanic rules at my LBS say no grease on carbon frames, and no grease in the frame when u're putting in a carbon seatpost.

Oh the myths perpetuated about carbon fiber.

I remember when I bought my Kestrel 8.5 years ago. All my friends laughed at my new plastic bike. I told one guy that you could only ride it in a certian temperature range since it would get soft at temps above 95 and get brittle and possibly shatter at temps below 30. He actually believed me. More conventional wisdom for ya.
OK! No grease . . .tmguy

Wiped it dry last night including the seat tube. Left whatever residue remained and the post went in no problem. Thanks for the imput.
