My carbon EC90 seatpost is stuck in my titanium frame (Merlin Oreas). I have managed to move it out about 3 inches but looks like I've got about another 3 to go. It twists and turns but I just can't get it out. Watched on YouTube someone pouring a kettle of boiling water on one. Will it work? Like I say, it's turning round but maybe I'm just not strong enough to pull it out.
Any ideas please.
Warming the frame with hot water or a hairdryer may expand the frame just enough to get it out.
And the hot hairdryer won't damage my frame?
Not unless the hairdrier is a blowtorch 😉
The melting point of titanium is 1667°C so if your hairdryer damages the frame, don't dry your hair with it. Excessive heat will damage a carbon seatpost, but a hairdryer should be safe.
I'm not very mobile at the moment as I'm post surgery (walking wounded) hence the time to fix my bike so I'll try the hairdryer today. If I see the guy next door I'll ask him to help. He's probably stronger than me.
If you can twist it in the frame then it isn't stuck. Not being pedantic, just reassuring you that it will come out with just a bit more oomph.
Also if you take it to your neighbour make sure he knows the cost value of the frame vs. the value of the seatpost before he clamps the frame in his bench vice.
Good option if you have a bench vice is to get everything off the frame, then invert the lot and clamp the head of the seatpost in the vice - you can then use the leverage of the frame to get more freeing force onto it, and pull the frame off the post vertically upwards*. This may obviously cause some damage to that nice carbon head, but of the two the frame is the more valuable, so that would be preferable I guess!
