...Al seat tube. Dissimilar metals, possible galvanic reaction, etc. I searched old threads, but found nothing certain. Do I need ANTI-SIEZE compound or just regular grease?? Thanks in advance for an informed reply.
Any time Ti is used in an application.......gogene

....it's best to use an anti-seize. Regular grease will work, just not as well. In an application where the Ti item won't be removed or inspected regularly, like a bottom bracket, anti-seize is a must. In your seatpost application, where the seatpost will most likely be removed or moved frequently, grease is fine.
I'm always amazed at how different people are.dzrider

I use anti-sieze where aluminum parts touch steel. I would do the same with Ti/steel or Ti/aluminum. So, while we're in pretty much agreement there, I only move my seat post to keep it from seizing. I can't imagine fiddling with it for any other reason and don't consider it a part likely to be "removed or moved frequently" like my bars and stems.

use the anti-seizeDougSloan

Anti-seize contains copper dust that grease does not, and for some technical reason beyond me this prevents galling. Grease can work, as it physically separates the two metals, but if it gets thinned enough or washed out, you might have trouble. If you have any Ti on the bike, get a tube of anti-seize and use it liberally -- cheap insurance.

anti-seize for same metal combinationsChainstay

That's what I heard too, but galling takes place between the same metal. Some of the posts said above that the anti-seize is to prevent galvanic corrosion which involves dissimilar metals. With disimilar metals is anti-seize still the best product?
