Ok so im sure this has happened many times before but I have a Renthall seatpost that came with a bike i purchased the other day & it's  severely stuck in place in the frame  , i've tried spraying gt75 every day for the last 4 days where it enters the frame & also down inside the post in to the frame & then turning the frame upside down in order to get the oil to soak in from the inside . Then i've had it in a vice but it will not move at all.

Any methods that have worked for you guys wold be greatly appreciated as this is annoying the hell out of me.

Cheers :daumenhoch:

Ok so melting it out gradually with caustic soda is a final option  :D

First try giving the post a sharp smack down further into the tube with a hammer to break the "seal" then try it in the vice again
If its slipping in the vice drill a hole throught the top of the post big enough for a decent sized alen key or something similar and try in the vice again

Other options are:
Cutting down the lenght of the post with a hacksaw blade, a ballache!
Drilling out with the right sized bit, difficult  :(
Heat? not the greatest of ideas usually
A bigger vice  ;D
