Seat Post stuck in carbon frame

[yeboabe]

So after 3 nights of cutting and cutting i managed to get 2/3 of the post out the bit that was stuck is still in there but have dropped to the botom, so now i can insert a new post but has to be 300mm long max for her leg length!

 

Mine was a bigger problem since the seat tube was all the way in, so on a full hack saw blade i could only hold onto less than 100mm if i wanted to cutt all the way down.

 

Some tips,

 

Make sure you cutt all the way thru the tube before trying to curl it with pliers.

 

I had to cut mine into 1/4's , to help get it loose.

 

Don't rush things, work on it over a couple of nights!

 

but now i can use it again.!

Preventative maitainence is the answer here. Once a month loosen the seatpost bolt, rotatate seatpost back and forth, re-tighten. 1 minute 12 seconds well spent.

agree with Veloce, loosten post once a month.

 

I had some good advice from JB just before this years argus. 20cm of Carbon seatpost stuck in a alu frame.

The grease had emulsified and swelled = stuck post.

No twisting would budge it.

Took many kettle fulls of boiling water, poured over the end of the seat tube where the seat sat, one kettle at a time with a twist and pull between kettle pours. this allowed small increments of extraction 2-5mm, and finally after many hours the seat post came out.

Alum expanded with the hot water, thus allowing the post to twist out a bit till it cooled.

so far all good since.

thanks again JB.

jeez, now you guys remind me that I still got to solve that darn stuck seatpost prob (which I've avoided) as discussed in the previous thread.

After reading all the suggestions above, I first tried the boiling water option before considering the demolition option. 4 kettles later and the carbonpost came loose! Now, deciding whether to stay with the carbon post or fiting the alu one.

thanks for all the suggestions above, it saved me a seatpost!
