So .... I have an old frame from which I hoped to remove a fluted seat post to use on another bike, but its stuck fast :(
Have given it a good old heave ho whilst the saddle was on and, in frustration once the saddle was off, a good tw*t with a lump hammer - which moved it further in by about 3mm.....
how the chuff do i get it out guys???? :-[
-
Put the seat post in a vice and use the frame to twist it out, if you don't have a vice try clamping a stem to the post to give you a bit of leverage :daumenhoch:
-
Drill a hole (near top) through the post, push metal bar/screwdriver through.. Twist n turn til out.
-
If all else fails you can saw it off and use a strong caustic mix to melt it out.
-
Maybe you can heat the tube a little ....
-
If it's an aluminium frame drill it out as all the twisting and tuggind will probably snap the frame :crazy2:
-
as above. in the worst possible case a few devilocks may help !
or you can try bendys advice and leave it in coca cola overnight ! ::) :LolLolLolLol:

My stuck post wasa alloy renthal and it has fused to the metal frame - snapped the top trying to drill a hole in it to twist the top (it was fused)
if it has moved 3 mm then i would put it in a vice and twist it out using some man power :knuppel2:
got it out in the end - just got to get it welded up from the previous owner
