seat post stuck

[Bruce D]

Can anyone please help, my seat post is stuck. The frame is carbon and seat post is aluminum. 

 

Thank you.

The short answer is, coke.

CO2 Fire Extinguiser. It shrinks the aluminium and not the carbon. Had the same problem. See you tube video about it

This.  Seal top of seatpost, turn frame upside down and pour coke into the seat tube.  Leave overnight, will probably still require a bit of force but the coke should loosen the corrosive grip.

Coke and pipe clamp

Also clean the next(yes buy a new one)  seatpost very well and use carbon paste when inserting into frame.

 

Then also take it out every 2 months and clean well again.

 

You should not have any problems if you stick to that.

 

good luck with the removal.

If one of the surfaces is metal (any kind), use grease, if both are carbon, then use fibregrip/carbon paste
