polybikeuser Don't think that would have solved the carbon to carbon binding problem though and thats what really freaked me out. Anyway I now have a nicely shimmed down USE Alien aero seat post fitted to the Pedal Force which is super lovely and a plastic shim between the post and the seat tube which I'm hoping will prevent binding from occurring again.

That should do it !

I am sure you are aware, but in case your not, you do know you must not use grease (of any kind) on carbon parts, it causes them to delaminate - which to me and you would appear as the carbon swelling (and binding).

On my carbon parts I use assembly paste, it stops carbon from slipping and makes it easy to slide carbon parts out (seat posts especially).
