Seized Seatpost

[BigTom]

Long story, but a recently acquired bike has a seized seatpost. It is a KCNC Scandium seatpost in a carbon frame. Anyone have any magic tricks for getting it out? I've read a lot of the online articles, but haven't had any success as yet. Hoping to be able to get away without having to cut the seatpost out.

I overheard someone recommend unicorn spit as well.

Hacksaw and lots of patience is the only remedy. Been discussed plenty of times on here.

Just in case you need it, this is strike 3 for the hacksaw method. One of the other methods may work sometimes, and on not-too-seriously-seized posts, but surgery is the only way if it's properly stuck.

 

Edit: There is actually another way - it involves a shaft clamp and a brace and some bolts, clamps the seat post and braces against the top of the seat clamp so you can use the bolts to jack the post out of the frame. I think it was mentioned in the thread that's been linked to.

 

I can't guarantee it'll work since it's not something I've tried myself, but I'd give it a good chance at least. The hacksaw method will probably be cheaper and quicker though.

Thanks for all the suggestions. I FINALLY succeeded in getting the seatpost out last night. Many days of pounding and twisting and different penetrating lubes. But it is out. I’m not sure if it was the combination of everything or just finally got the right one in the end. The last one I tried was Q10 (not Q20). I put lots of it on and let it sit overnight, and then lots more and was finally able to get it out. I removed the saddle attachment which left a good size hole on either side of the top of the KCNC post. Inserted a long screwdriver through the top and hit the handle with a rubber mallet. With all the Q10 in there, it worked!

Now, does anyone have any suggestions for how I might be able to remover all the "gunk" on the seatpost without removing the gold finish?
