- The aluminium seat post had corroded inside the steel frame of this fixie bicycle. When I tried to grab it in the vice and twist the frame off it just sheared down inside the tube. So I cut a slit with a hacsaw and padsaw and then folded the metal inside until it became loose and fell down the tube. Then I cleaned out the frame with a wire brush and subsequently a file and eventually I was able to get a grip on it and pull it out.
No, penetrating oil did not work, I tried that first, WD40.

I did the same with a stuck handle stem, but I've had to cut a strip, both side to clamp the tube and "shrink" it to get it out
Well done....where there is a will there is a way .
I've seen an Indonesian video where the mechanic used a couple of nuts locked to the end of a threaded rod to pull the post out. My own recent experience was that sawing internally worked pretty well. By cutting the seatpost off then cutting a slot in it with a metal disc on an angle grinder, right down into the frame slot, I ended up with only about 6" of the post to saw through.
Fair play to ya for sticking at it. I've had a few over the years that were flippin nightmares ! . ...
You'd think they'd stop mixing aluminum with steel at this point. Just make steel posts!?
Persistence improves resilience, remote upload in the absence of brute force, cheers
Thanks for the vid! I was honestly thinking of buying a big drill bit to bore out the metal little by little😂 but I’ll attempt this. My mission now is to go to Home Depot
Well done 😊. I’ve got some corroded headset spacers to remove now!!!
6:22 some of my teeth loosened when exposed to that squeak! Metal fingernails on a Mr Muscle polished blackboard stuff! Great job getting the seat-post out, I'm going to have to try something similar on a bike I picked up for free!
Excellent work! The only thing I would have done differently is take the bottom bracket out before the sawing. I'm at this point right now with mine. Sawed on it for a couple hours. Now I'm letting is soak tonight with penetrating oil (probably won't help at all, but it's time to take a break anyway). Tomorrow this thing is coming out!
great, I now know what hell to look forward to
I think cutting and sawing out is the best way to go when it’s really corroded like that.
the most hardest way I've ever seen
Im not envy you man coz I passed through all this by myself 😊
i have a broken Carbon fiber post break at the edge of the seat mount, will try your cutting method indeed, thank you
Maaaaan. I am doing the same. Mone is going to be a bugger though
I'm having similar struggle...2 hours into it so far...I must win
did you win?
@bootsowen not yet...it's totally mangled inside the seat tube now so it's going to be caustic soda I guess 🙈
If the aluminum seatpost and aluminum frame are stuck, how do you remove it?
I would try the same way, but I would be a bit more careful.
@@bootsowen it's too risky, I don't want the frame to be damaged, it's a pity if that happens, but I'm confused 😭
Why not just saw it out gently?
@@bootsowen oke I will try
What is the name of the red tool that you used at the end called ?
What time?
Needle nosed pliers
a bit of lye will do te trick, or maybe some galium
Slide hammer it out
Slide Hammer with a toggle bolt attached to the end. Trim back the sides of the toggle so that the face catches the bottom of the tube.
