seat post – to grease or not to grease?

had a bit of a nightmare recently with jammed seatposts. (carbon post in allow frame, and alloy post in carbon frame).

Building a cx bike at the moment, and am opting for alloy/alloy to try and prevent and carbon bonding thingmyjiggers.

So with an alloy post in an alloy frame, do you use any kind of grease or other stuff when installing the seatpost?

grease will be fine.

grease it – or coppaslip if you are not going to move it often

what kind of grease?

Had a problem of seatpost slipping when bike was new, shim was too big to solve problem so bike shop gave me some carbon grease……grease with particles of carbon in I assume, never had a problem since. Dont know if this is any help to you though!

I greased a seatpost once. It slipped. A lot.

Carbon grease is not carbon grease but carbon assembly compound it’s grippy because of what’s put in it, some enigneering type on he will explain better. For your bike I would coppaslip it as mention the stuff’s toxic so be careful but it is very resistent to water. I went to a seminar on carbon and how it’s used in bikes by a carbon frame designer and he was laughing at how we get sold tiny little packets of that carbon paste when he had seen it in massive containers in industrial use for next to nothing in cost.

can someone give me a linky to what type of grease I should use for the seatpost, if any?

Ive never greased before, but then Ive got 2 stuck seatposts, perhaps i just need to move them more often?

Any grease will do.

As above, any grease will do. I often just use silicone Bike Spray on my woods bike as I move the seatpost a lot and it gets cleaned fairly regularly. On my other bike which I do not move the seatpost in very often at all and use mainly on roads so don’t clean it as often I use Copaslip.

For a seatpost that is not moved often any grease will not do – coppaslip anti seize compound is the right thing to use. grease willbe washed out over time, coppaslip leaves a residue of copper that acts as an anti seize compound.

which is better park, shimano or finish line?

finish line seems best value?
