1;
is there any easy way to remove a seat post thats stuck solid its been soaking in wd-40 for about a week and it just wont budge.

2;
has anyone found a source of decals for the gs as mine came off in about 500 bits as they were scuffed to buggery to start with.

i would settle for good copies or nos would be much better although I'm not fussed either way

cheers
Rob

Re: Seatpost

I think most of us have had this problem.

Obviously WD40 is the first step and youve done that with no success.

Next step have you clamped the seat on and twisted to high heaven to try and budge it.

The you can always..now this may seem daft but try knocking the post in a bit further to try and shift the rust that is holding it, then soak again with WD40.

After that its the vice trick. use a heavy duty vice and clamp the seat post into it obviously ruining the post in the process, the grab the frame and twist like mad, this works on most occasions.

If still nothing and proceed with caution on this one, you can use gentle heating of the seat tube then twisting. this is a last resort and be careful as you can damage the frame.

Lastly send to an engineers and get it drilled out Shocked

Any other pointers from other members they may have done something else that has worked Wink

As for the stickers i dont know if stuey has sorted any but if he has i want a set too Very Happy

try driling a hole through both side of the seat post, stickin something like a screwdriver through both holes, find a "slot" that wont move ( a crack in the ground), stick the screwdriver in the slot and move the frame until free. This might sound daft, but I have removed 2 unmoveable seatposts this way Shocked

This is pretty obvious, but hasn't been mentioned in this thread yet.

Take the clamp off the seat, tighten it onto the post.
Next get a large wrench attached to the clamp and try twisting (you only need to get 1/2mm of movement before you know it's working).
This way gives you much more leverage than twisting just the saddle, and it doesn't damage your seatpost.

Now restoring an old mk 1 tuff burner, bringing back memories of my youth. anyway the post was stuck well in the frame and was vertually all the way in Exclamation previous owner had already drilled a hole in the post but couldn't get it out.

I removed the crankset, seat and clamps. with the crankset out theres a hole where the seat tube joins the bottom bracket. used a can of "plusgas" which is a dissmantling fluid, spray post round the top and bottom through the hole, leave abit then get physical.

and
-clamp the offending post, with a handle bar stem
-use an old one, as it will fit on the thin part of the post
-do it up tight and you will be able to twist
insert longer bar over stem for leverage
