Seat Post Stuck

[IvanM]

If someone could either advise me or point me to a LBS to remove an aluminum seat post which is too tight to remove from a carbon frame. I'm too scared to overdo the force in fear of breaking the carbon frame. Tried anti-siezing spray etc. but to no avail. Slight movement from left to right but that's it. I live in Cape town area

If you have slight movement then keep on with the anti seize let it stand longer atleast it's not seized solid

Get access to the seatibe through the BB and then fill the seat tube with coke and leave overnight

Maybe bomb it with a co2 cartridge?

I think he meant coca cola, not peruvian marching powder.

Bags don't mess as much when they remove them at airport security.

So I will try the ice pack and co2 cartridge. I did feel the seatpost getting warm where it meets the carbon frame and the it almost siezes solid. So the video does make sense. I will post my results. Thanks everyone

I have used boiling water to remove a Pinarello post.

Never had any problems but that said others have had carbon cracking etc.

maybe last option but that would be your call.

Wrap an ice pack around the seat post for 15 minutes. Aluminum has a high coefficient of expansion, carbon fibre practically zero. The seat post will shrink and can be worked loose.

Boiling water will make it tighter as the seat post will expand. Coke will make a mess.

The cause is galvanic corrosion between the carbon fibre and aluminium. Periodically remove the seat post and clean off the oxide, lightly grease and reinsert to prevent seizing.

 Carbon Craft @CarbonNinja is able to remove the seatpost. Your seat post will be sacrificed, however, your carbon frame will remain undamaged. His shop number is 071 896 2231

The correct solution is replace the ally post with a carbon one.... Remember some carbon paste when assembling, and bob's your aunt.

Coke in the frame is the biggest lie ever. 

You want ants? That is how you get ants.

Thanks for all the comments. So tried the freezing thing and can just get the seatpost to turn 15 degrees each way. Just a bit scared about the damage I could create so have phoned carbon craft. Will book in with them. Thanks all
