Ok so I was JRA and I came hoppin' off this root on my favorite trail, maybe about three or four mile in on a 13.5 mile loop and SNAPPP!!!! there goes my CT2 carbon seat post right at the top of the tube. I'm ok (could have been the worst sadle-sores ever), but now I've about 6in. of carbon-fiber stuck in my seat tube. And it's in there good.


Anyone have any ideas how to get it out??????????

Thanx;

The obvious one would be to invert the bike the seat post should pop out (don't forget to slacken the seatpost clamp).

If that doesn't work have a go at what I just thought up seconds ago...
- Get a cork from a wine bottle and tie a piece of string 2/3 along the lenght of the cork.
- Lower the cork with the shorter end first (short end from the point you tied the cork), if its too fat trim the cork down and try again.
- Pull up and the cork should rotate inside the tube to grip the post and gently pull up.

You either get the post out or have both the broken seatpost and cork stuck down the seat tube.

As stated above "it's in there good". The post has always been a tight fit, I've always had to twist the seat back and forth to side it up or down. There is only the smallest bit still above the seat tube (not even enough to gab with vice grips, it just crushes, only about 1/8" or less). I've tried a bent (fish hooked) wire (super duty coat hanger) w/ no luck.

This is fairly frustrating, any other help would be great.

Thanx

Use a hacksaw blade.

Cut the seatpost from the inside using a bare hacksaw blade.

I came up with another untested idea:
1. Remove the cranks and BB.
2. Invert the bike and spray a ultra slippery lube down (or is it up) the seattube.
3. Give a good shake.
4. If that doesn't work, use something to ram the seat post down into the BB area.
5. Using the 'saw idea' from above and saw the across the seat post.
6. Tie some string around one of the notches, with the string inserted first from the entry of the seat tube.
7. Again gently pull up and seatpost hopefully comes out.

Yes this is a slow method, hell while doing this you can check the crankset and BB for wear.

If that fails, you can take the slower but more effective method of sawing the seatpost an inch at a time at the BB area.
------------------------------------------------

And the epoxy idea from steve3 is great for your situation where the seatpost is jammed at the top. Just epoxy your super duty coat hanger to seatpost, cure and yank it out slow.

If the 'weld' fails after you move it out a couple of millimetres, keep repeating until you can either vise-grip it out or drill a hole big enough to fit a piece of solid metal into and pull out.

Damn that seatpost is a bastard to get out!

Just tap another fancy carbon seat post in on top of it...

Just tap another fancy carbon seat post in on top of it... assuming your seat post tube is longer then 12 inches you should be fine -- problem solved.

Thanx guys

I think the epoxy/JB W. idea sounds the best, hopefully i'll have time to get to it tomarrow. I'll post and let ya'll know how it goes

Where is your mind at?

You also might be able to find large carrier bolts from Home Depot nearly the size of the post. If they're close, you can try to BJ Weld it in there ( i would use the overnight and not the quick stuff becasue it's not as strong). If you can thread it in there carefully, then try it. I think the epoxy method is safer.

It is JB weld, not BJ weld. (Whatever THAT is...?)
