Grease aluminum post on my carbon bike?
I heard of don't grease carbon posts but what if I have a carbon bike with an aluminum seat post. Should I grease post with anything.
What type of products are safe for my post or because it's aluminum it doesn't matter?
you don't want to use grease. your seatpost will always slip, that is, until your post absorbs all the grease and then becomes one with the carbon. you want to use a carbon compound. it's designed to use specifically with carbon & whatever other material you throw it's way. you should be able to find it at your LBS.
