Any magic involved in going from alloy to carbon seatpost?
I know that grease + carbon post = weakened post. I'm thinking about snagging a carbon post to replace my alloy one, though, and am wondering if I should take any precautions beyond cleaning the seat tube out. Seems like that would be all there is to it, but it never hurts to ask.

Philosopher's stone? Wait...wait, that's going from lead to gold. Don't know what you'd need to go from aluminum to carbon. You'd have to gain a bunch of protons and electrons 
Here, let me save you the trouble: Smart a$$!

Nah, you're cool. It's in the seatpost makers' best interest to make it an easy thing to change.

Just make sure it's the same diameter!

Just clean out any residual lubricant and check to make sure that there are no sharp metal burrs at the top of the seat tube which could dig into the carbon seat post (at least that what my USE Alien brochure says). And, be sure you do not over tighten the seat post collar. CF is not forgiving like AL.

be sure that you DONT install it on a full moon. the increased lunar gravity (no joke) will cause a reaction between the air, your seatpost, and the frame to create Aluminum Carbonate (AlCO3), which is pretty toxic stuff--it'll drip down to your BB and make your cups brittle. They are then prone to shattering unexpectedly while climbing. Of course, if you wait and install the seatpost on a new moon AND ride your bike 20 miles or so before then next full, the static vibrational energy of the riding will get rid of any ionized radicals that might catalyze the reaction. be careful.

My God....I've been so close to disaster!

Magic? The ease with which the industry is able to get over $100 for something as simple as a seat post.

Moot point. Couldn't justify an extra $100 for 20 grams of weight and not enough of a difference in the ride (on a steel frame) to make it anywhere near worth it.
But thanks for the tips. I'll be sure to remember that lunar stuff. Combine that with the altitude here and I could have impaled myself.
