I currently own a Cannondale Synapse. The carbon seatpost is held in place by two aluminum wedges tightened against each other by a stainless screw. As stated in the manual, I greased the screw threads and the faces of the wedges, so that any metal-on-metal is greased. I used carbon assembly paste on the post and seat tube and torqued everything to spec. Everything is holding firmly in place and it's now completely silent (was creaking a lot before using grease on the wedges faces).

I'm wondering if it's really worth it to disassemble all that, clean and regrease it from time to time? I unthighten the post and move it just a little from time to time to make sure it won't seize, but since I don't ride in the rain, I'm not sure there is a point to re-greasing static parts and re-applying carbon paste. As long as it's still quiet, I guess the grease is still doing a fine job, and without water there isn't any reason to worry about aluminum on carbon oxydation?

Well I move it every six months or so. Haven't regreased it in 18 months. Maybe I'll do it before hitting the road this spring. Everything else on the bike has been regreased at the end of the season, I just asked my mechanic not to touch the seatpost during my year end maintenance.

By the way, I already use a piece of tape to mark height but for some reason I never thought of using it to mark orientation too. I always end up readjusting it two or three times before getting it right. I'm as awfull at doing it by eye as I am lining up my putts So thanks for the tip!
