After opinions on best practice when using a carbon seatpost is an Alu frame. As I'm about to stick one in for the first time. :shock:

Carbon paste (or could it cause seizing with the aluminium)
Thin layer of grease (to avoid seizing)
Or go in dry :oops: (and check for seizing often, say bi-monthly)

For info the previous post was alloy, and was inserted dry, but comes out without too much fuss.

    Carbon past , IF you mean paste with small particles ....io reduce the clamping force and to prevent seizing.

    Finish Line fibre grip or Morgan Blue assembly paste are the options.

    Carbon paste will be fine.

    A carbon post in a metal frame shouldn't have seizing problems. Most seized posts are metal on metal and caused by some form of corrosion (steel to alu is particularly bad for this). I've heard of a few examples of carbon posts expanding when greased and sticking because of that but I don't think it's common.
