I have not used my aluminum bike for a long time and need a little adjustment on seat height.
But my carbon wrapped post stuck! I have used a LOT of penetration oil to make it move and finally it is slowly coming up. I did not take it off yet, but as is rotates around it will be no problem, I think.

Is there a better way to take it off?

What oil/lubrication to use to prevent stuck post in the frame?
What is the lubricant that will not make the post go down?

Thanks!!!!

You have to rigorously protect against moisture which could set up Galvanic corrosion. IIWY I wouldn't use a lubricant next time, just carbon assembly paste. Buy a tube on Amazon.

Your post may be totally seized. This has happened to be before.

You can save the frame, but the post is toast. Saw the post off shortly above the seat tube/ top tube junction of the frame, and then use a hammer and a chisel to scrape the post out of the frame. Make sure you use a respiratory mask of some sort to avoid inhaling carbon fiber dust, esp. during the sawing.

I have read about it, but keep my hopes I will be able to take it off. If I have to cut it, I already have extra post.


Is this the paste you are talking about?

If so, I do have it already

Good. Or the much cheaper Finish Line stuff shown here: https://www.google.com/search?q=amaz...540&gws_rd=ssl

while we are talking about stuck seatposts, I have to ask about a penetrating oil.

I once heard of a product that worked well on stuck posts. It's not PB blaster or any of the common lubricants, but it was well known by a few people that restored old automobiles.

Does any of this ring a bell?

Was it Kroil?

That's the stuff.

Thanks.
