Jusrt bought a carbon seatpost for the rebuild. Never bought any carbon parts before. Is there anything I need to do before inserting this into the seat post? I know I have to make sure at least 100mm is in the post. But does it need to have any grease on it or anything like that?!

    Don`t grease it but use something like tacx paste or carbogrip to stop it slipping and so that that you don`t overtighten it. Although now i`ve seen it that`s a carbon wrap seatpost anyway not a carbon one.

    Grease can be fine.

    contact the post maker for the correct treatment.

    what is the frame material?

    are you running a shim?

    Most of them in your link seem to say absolutely no grease as far as I can tell.
    It pretty much confirms what I said.

    Grease can be fine?! Didn't look like that from those initial comments. Reading further down I can see that certain types of grease can be used.

    There's a web address on the seat post. I'll check this out for info.

    Frame material? ....... erm ....... steel alloy?! It's not carbon or Titanium that's for sure. I'm not sure exactly!

    What's a shim?! :?

    a shim, if the seat post is smaller than the seat tube you may use a shim to fill the gap.

    personally I grease carbon if there is no shim. if there is a shim i grease that.

    But if the maker says no grease then no grease.

    As to FSA I cant remember what they say.

    What kind of grease do you put on it ? Mine slid down without any grease let alone with it.

    from the FSA pages
    How do I install a carbon seat post?
    Before you start you should check the frame’s seat tube for sharp edges. Remove any such sharp edges or
    burrs.
    Check for correct fit. Seat tubes and seat posts come in many different diameters. Make sure you have a
    seat post that matches the inner diameter of your frame seat tube.
    Clean all existing grease from the inside of the seat tube. Apply FSA Installation Compound (included with
    carbon seatpost) on the seat post.
    Insert the seat post into the seat tube. Do not use rotating motions as this may scar the seat post. The seat
    post must be inserted far enough to cover the minimum insertion line.
    Tighten the seat post binder to the torque recommended by the frame manufacturer.

    I guess you got no manual or compound.

    Maybe because it`s an alloy seatpost and not a carbon one.

    Nope! :?

    Thanks for posting that info. I've not even had a chance to look at the FSA pages myself. As I said there's a web address on the post itself. I'll check that out when I get a chance

    Cheers :)

    I got a full carbon post a while ago, I just stuck it in and hand tightened it, worked fine.
