Not having much luck with bikes at the moment.
Hub on commuter road bike went on Monday morning, took it to bike shop to find whole drive train, headset, cables and front brake are gubbed!
So now commuting on the MTB. felt like the saddle was a bit low so tried to raise it when I got home ( not quick release, but double Allen clamp), only to find the seat post ceased in the carbon frame.
I've wiggled it, jiggled it, wrapped it in an ice pack but it won't budge!
Not tried coke yet, but not sure how doing a few lines would help, except from an imagined sense of strength.
So any tips?
Jam the seatpost in a vice and twist the frame.
Tap the seatpost down (a little!!!) with a plastic/soft mallet to break the "join".
carbon frame? Be very careful 🙂
Try tapping it down, try holding he saddle in a vice ad twisting the frame
Rubber mallet crap...metal will provide greater spike.
If it won't come out, cut and slot it and stick a smaller one inside.
Shall we all chip in and buy you a maintenance book?
Lots of WD40 or similar penetrating stuff and leave overnight.
Then take to LBS.
Sheldon Brown suggested that oiling a carbon frame is ill-advised:
[Bad idea: oil expands the resin binder of the composite material and can deteriorate it.]
Have a look on his page for a variety of options:

I had the same problem, tried all the suggestion I found on the web but no luck. In the end Argos Racing Cycles sorted it for me, cost £30 and they got it out with no damage to the frame or seatpost.
