I am considering a carbon seatpost for my raleigh airlite 400 - bike fit has been checked by lbs but I still suffer from lower back pain on longer rides, meaning I have to stop frequently to stretch out. I don't expect a new seatpost to be a magic fix but hope that it might help smooth things out a bit.

Are carbon posts ok in alu frames? Do I need carbon paste or grease? and finally, does anyone have any experience with this easton post, which seems cheap atm?

    You will get more benefit from running a wider rear tyre at a lower pressure if you think vibration is causing soreness.

    I used to get lower back pain due to running too large a frame. Now that I can move my saddle to the correct fore/aft position it has magically disappeared.

    And, to answer (some of) your questions, CFRP posts are fine in aluminium frames, they usually come with a tube of paste but grease is fine too.

    If it's happening on longer rides, it could be a core strength issue. And I would still look at bike fit as a possible cause even if the lbs has checked it. I use an alu Thomson seatpost on long rides and it's fine. Do you feel as if you're over-reaching?
