I have never lubed a seat post and never had one stick :shock:

Reading all the posts regarding stuck seat posts I am coming to the conclusion that I have just got lucky!

Prudence has come calling and I now intent to grease my Al seatpost in my Al frame. Can I use any old synthetic or lithium grease for this task or is one better than others?

Any help greatly appreciated

    The main problems occur due to corrosion with dissimilar materials i.e. an alloy post in steel/carbon or a carbon/ti post in aluminium. For your alloy post in an alloy frame, a normal grease or anti-seize will be OK but for carbon, many manufacturers now recommend a proprietary 'carbon assembly paste' which is a non-petroleum lube with glass beads for added friction. Taking out or tweaking the post monthly as part of regular maintenance is a good preventative measure.

    For metal post in metal frames I just use the same pot of grease as I use on the cars, and as Monty says, take the thing out and redo it every so often especially in the wet.

    In my new Alu frame the carbon post kept slipping down till Epic sent me a little sachet of carbon assembly paste. Kind of red goo with a slightly gritty feel (plastic beads apparently) which has completely eliminated the slipping at a much lower torque setting.
