Just ordered a new carbon seat post to go with a Ti frame. Should I lube the post before inserting and if with what? Any other tips to ensure post doesn't move but doesn't seize either?

Cheers.

    carbon assembly paste. NOT grease. Apparently it can do funny things to the resin.

    Just shove it in.

    If many years down the road it is seized remove the bb insert an can of coke and presto it is free
    Don't know the Rules?

    Thanks guys,

    Have read mixed reports about various pastes / compounds etc. Carbon assemby paste appears recommended where both elements are carbon, but not necessarily when carbon is mated to Ti as far as I can see.

    Not sure I follow Rule74Please. What do I need to do with the can of coke to unseize?

    Seat post on order from CRC so hopefully guidance will be supplied.

    my wife's carbon fibre wrapped seatpost was slipping down her old alu framed bike. carbon paste sorted it.

    I now use this paste on seatpost and stem parts on our alu and Ti frames. You need less clamping force with this type of paste.

    FWIW I seem to recall reading somewhere that Carbon seatposts can seize up and there have been lots of people chiming in on this forum about just that happening. However, I disagree that grease or oil of any kind will damage carbon and or it's resin. I do know for a fact that one of the few things that WILL damage it is paint remover. I used grease for years when I had a carbon post without problems of any kind and never had one stick or seize.

    Appreciate everyone's comments. I checked with manufacturer (FSA) who were less than useless. My LBS recommended carbon assembly paste too. Didn't have any for sale so gave me some from his workshop in a little bag for free. This is why we like LBS.

    All fitted now and seems fine.
