- The seatpost on the thrift store bike I bought was completely frozen. Watch my adventures in trying get it unstuck. I eventually got it out. The bike is a Mongoose Sycamore with a Cro Moly frame. The seatpost was aluminum. It appeared to gotten corrosion down inside the seat tube. I resorted to using penetrating oil, ammonia, apple cider vinegar, cold, heat, pipe wrench and a cheater bar.
Here is a new video that I did:

Hahaha.. so very true
Going to have to try this my self I yesterday brought a raeligh Alaska as money is tight and my bike got nicked some weeks ago it cost me ten pounds and all all food but seat post stuck one saving grace is it's a short seat post not a long one
The lovely relationship between steel and aluminium, you can't weld them together but they do it on their own.
LOL!
alu is even magnetic
😂😂😂
Absolutely man, dang. I have one again

Love your channel! Best down to earth, real life repairs and tips.
I just extracted a post which had been stuck since the mid 80s. Mine came out easy... I turned the frame upside down and squirted WD40 from the BB hole. I gave a few squirts every week, repeating for 8 weeks. Then I clamped the post in my bench vice--two firm twists and it popped!
Amazing how calm you are when things don't go right. You are so calm practical and logical. Victory!!!!! Brilliant!!!!
im freaking out, mine is cemented in
This is a true lesson in life. What an incredible video! I've been batting a stuck seat post as I try to restore a vintage bike from my family and just watching this gives me hope. Thanks man!
I applauded at the end! You knew that this was a problem that actually had a solution, and that it was simply a matter of testing them out. This was one of those character-building, transferable trials. I'm so glad I came across your channel, RJ, and you're a lot of fun on FB, too! :)
I just spent the weekend struggling to remove an aluminium seat post from a steel frame. Thanks so much for this awesome video and for your advice. Applying ammonia with a dropper did the trick! Pipe wrench was also helpful for loosening the post. Thanks buddy!
Thank you. Now I know how to protect my seat from being stolen!
I broke a sweat watching this.
try watching the ending with your eyes closed, it's a totally different experience
sounds like sex
Rob Tyler try watching with your ear closed its like he easily took out the seat 💺
Taylor Pearl hahhaahahah lmfao
YEAH lol
Yup... I had to lower it pepole were passing by looking at me funny lol
Worked on turbine engines and in the hot section we used torq CB - kimball Midwest on seized bolts. Works like magic. Remove the BB spray in the frame towards the seat post through out the day, let it sit overnight. Remove saddle and twist on vice. Comes out like a charm. If that doesn’t work, try dry ice to shrink the seat post
This is a man I admire. He always wins in the end.
Amazing how stuck the seat post was - it wasn't even that far into the seat tube. Well done for getting it out!
Thank you sir,I appreciate your demonstration...now at least you gave me some hope of getting my seat post unstuck on my 82 trek .
Note to self: apply anti-seize to all 5 bikes' seat tubes, tonight!

This has GOT to be my favorite video of you. I can relate!
The BEST example that I have seen on removing seized bike parts.
The method you use is exemplary:Patience, various conventional techniques, repeating,repeating,and repeating again + More Patience.
Awesome!
Thank You!
Shaun Blackstock I also appreciate how you did this in "Real Time" Love ALL Your Videos! Very Helpful!
My goal was to remove the seat post WITHOUT damaging the frame. A seat post is easily and cheaply replaced. A frame not so much. Your guess is good as mine. I used ammonia, vinegar and PB Blaster. And lots of muscle to get it broken loose. If none of this works, you can also cut off the seat post about an inch about the seat post, and then hacksaw vertically inside the seat post.
Still looked dry on the bottom... go figure. The pipe wrench has worked for me Wrapped with leather or cloth. Then tapping up on the seat post with a rubber mallet and or board. Keep adding penetrating oil.
So impressed with your zen-like approach to solving seemingly intractable problems. If that had been me, many an expletive would have been beeped out! And where was your victory dance at the end? By golly, I would have strutted unashamedly for two days! Another great video dude
I had the same problem with the handlebar stem and a seat post on a Batteglin frame from the early 80's. I went through all the solvents, external freezing, ammonia, etc. - no joy. Actually, I had to saw out the seat post with a hacksaw blade, and I gave up on the handlebar stem because I did not want to chance damaging the frame. Last winter, the temps were down in the single digits for about a week, unusually cold for my area. The deck and siding on my house was "POP-POP-POP" (firecracker loud) all week long. I Googled about the noise and learned that the metal screws were shrinking because of the cold temps. I left the bike outside overnight and removed handlebar stem the next afternoon with moderate resistance. If I had only knew that when I took 4 hours to hacksaw the seat post with a blade. Hope this helps.
interesting read.
I might have to wait next winter to remove my seized quill stem, then.
So what are we saying cold temperatures makes steel more movable? Cold makes it contract right? Heat makes it expand right?
That video was sooo entertaining!! Thanks for posting. Very informative and a ton of fun to watch, especially if you've had the issue in the past yourself...
after watching this video I used the apple cider vinegar and have since removed 3 stuck seat posts. 2 were aluminum in aluminum and 1 was aluminum in steel. Wow thank you for the tip.
You gave us hope of removing stuck seat post it's been years to find any solution on my steel bike with aluminum post your the guy thanks!
I have the same problem. Now I know how much effort to put in to get the thing out. Thanks for sharing the experience.
Thank you for this video. Like all the others, thorough and helpful.
and people think im weird for greasing everything, even new bikes i check, and always check all of your nuts bolts.
Damn someone put the post on with a jackhammer. You tried alot of things THANK YOU for your hard work Sir
The most satisfying video I've ever seen. Can't wait to do this on my thrift find.
RJ the 'tenacity' guy... love your work AJ love it
This guy's patience is impressive. Had this happen to me before and tried many similar approaches. In the end reverted in inverting the bike and filling seat tube with Drano with some spectacular results! That stuff is evil and should be used with caution and only as a last resort. First it started smoking, then bubbling and gurgling and it all got very hot. The fumes were awful (good mask and thick gloves are def required). The Drano eats the alloy but not steel. Eventually left a thin sliver of seatpost in the frame that I could then remove.
sausage Yep, sodium hydroxide eats aluminum, but not steel.
Wonderful video, learnt quite a lot of new stuff, thanks. Now I will have a go at my seat post which is totally locked.
WOW, well done. great determination.
I had this problem a few years ago with an aluminum post that had been pounded into a steel seat tube that was too small for it!
Had to chain the BB shell to a column in my basement, attach a block and tackle to the seat rails and a second column. It took a lot of effort to add tension to the system, but it did the trick.
Man RJ , I am lost for words. Bravo & hats off again.

Good Video as usual, I had a GT MTB that I got cheap with a stuck post. I ended up cutting the seat post off and carefully used a hack saw to cut into the inside of the seat post is several places and that did the trick.
Hey man, I just wanted to say thanks for all the cool videos. They have helped me out on more than one occasion. I thought I'd return the favor by suggesting something that worked for me this week on a chromoly Trek 930 with an aluminum seatpost. In addition to the spray method used in video prying open the seat tube notch, I incorporated a plumber's rubber strap wrench. I was able to get pretty good leverage. That and some cursing under my breath did the trick and didn't ding up the seatpost. Anyway, hope that helps. Cheap tool. About $20 for a pair of large and small ones. Later.
I have strap wrenched, and thew wouldn't have worked on this. Maybe on a seatpost that is only a little stuck.
buit check out a few of my other seatpost vids:

Wow. What a patience you have. Bravo
I know I'm late here, but I've had good luck with clamping the saddle to a table vice, and then leveraging the entire bicycle like a giant key. Then again, I've probably been very lucky and not dealt with anything as stuck as this. I saw one of your quill stem removals, and I have literally never had to do more than hold the front wheel between my knees and give the bars a sharp jerk (no pun intended, lol)
That was so satisfying to watch. I have a frame with a seat that has been stuck for over a year now, and I'd like to finish my rebuild. I'm about to go the acid route.
Check this video. th-cam.com/video/S3ek2GeZzE0/w-d-xo.html
Thx this vid helped so much
Im building a trail bmx out of my old stolen bike co. Casino 10. The bike has been neglected in my garage for about five years. So far the seat post has been the hardest thing to fix
th-cam.com/play/PLxO5aF0sensiVdiClC_JH6OboqFl5Dvay.html
Yay you did it again and now I know what to do if this ever happens to me with my mountain bike
Worked with oil, I dont have the wrench pipe so I took a vice grip and have hit with a mace. Popped out in 5 minutes. Thank you.
Well done indeed! its nice to see a result! When ali and steel rust together its hell
This was very satisfying to watch
I can't wait till I pull my seat post up and out of my bike
Try getting a little vinegar down there to dissolve run. Use a pipe wrench on it like I did and keep turning it back and forth until it loosens up some more. When it gets loose, clamp some vise grips onto the seat post so you can turn it while pulling up at the same time.
Amazing persistence
you are good man... I have the same problem I'll try your techniques.. thanks
satisfying triumph over stuck bicycle!! Bike Guy wins again
You worked so hard on this seatpost...
You really earned this like!
lmfao
Consider selling or passing on this bike to someone that exactly fits this bike, at the "frozen" post height 👍
Or, Irony: new owner has super long legs and raises his new seat post way up to this old height. Thank God, no hernia RJ. 👌
I have a 1993 specialized rockhopper with a chro mo frame and alu seat post, when I got it it was seized stiff, put the seat post in a pipe vice and twisted the frame came off no problem! did the same for my vintage BMX steel post in steel frame
Amazing!!!!!!!!!!!! congratulations from México D.F.
But i realy admire your channel RJ it realy helps others from your teaching methods 😊👍🏼👍🏼👍🏼
Thanks for the tip. I have the same challenge. I will try it
Yeah I felt knackered just watching it !
Very nice! That is determination.
Nice!! I might have removed the seat and poured copious amounts of vinegar into the seatpost until the entire tube was filled 😅
The satisfaction in the end so gooood
I am watching this video thinking the same as what sparkyuiop said! As a lady, I find that trying to loosen anything seems to be impossible! You were putting your full body force into it and it still took a while for it to come free. I will give it a go, but looks like I will need to get a pipe wrench to finish it off. Nobody told me I needed to do body building before attempting to remove this seat post! ;)
Hopefully yours wont be this bad!
That was really satisfying at the end there
Thanks buddy. I was finally able to remove the seat after working 25-35 mins. I just kept twisting the seat left and right then it got to a point where it was so loose I was able to turn it with 2 fingers and rotating it good 360 and was turning in circles non stop.
It must have been so satisfying to finally get that apart after all that effort!
Your great RJ!!
Like Wile E Coyote trying and failing to catch the roadrunner each time he comes back with Acme Supply kit - Hilarious
You do very good job with that seatpost.
Had the same problem once. To get more leverage I took the seat and wheels off and clamped the seatpost in a vice on my workbench. Then, along with liberal amounts of WD-40 , rotated the whole frame around. As I did this the seat tube got red hot and it made a loud screeching noise. This way I was able to pull and rotate at the same time. It still took me a good 45 min but it came out.
Anyway , just one more option u can try.
cool 80`s mtn bike!
Hats off to you Sir...
Fantastic effort. Good video
Most satisfying vid ever
Dude, I would just give up and take it to a bike shop! You've deserved my respect
Fangyao Huang he did it without wasting his money
Crazy man..Destroyer.
epic battle. nice work.
God!! *Hooh* *hooh* that was really hard...pulling a stucked seatpost...I had the same problem too
thank you ! helpful vid
So satisfying
Congratulations... finally can open....😂👍👍👍
Leave the tires on. I had the wheel off in part of the video as I was going to work on the wheel. But ended up putting it back on. If a magnet sticks to the seat post, it is steel. If not, then it is likely aluminum.
RJ u rock
Drop penetrating oil, vinegar, moonshine or whatever down the post just just as you did and leave it overnight.Take the saddle and wheels off and put the seat post cradle in a BIG vice. You'll be able to use the frame as a large lever and find it easier to pull up at the same time. Has worked well for me in the past.
rj beast mode
I was rooting for you the whole video.
Well done, dude.
No one looks more like a man than RJ the Bike Guy just removing that post. Nor should they!
LOL!
you got it because you didn't give up. both thumbs up
Patience and persistent pays!
RJ... but how do you rust proof the steel fork, and other tubes of the frame besides the seat tube? Any recommendations? Thank you... I have a modern 2018 steel frame from Specialized.
Felicidades!! Al final se pudo!! :)
it took me around 2 hours to remove using the same method but I actually had the frame on the ground flat for more leverage.. Crazy hell of an experience!!
Keep in mind they are not all stuck the same.
I do the same thing with the pipe wrench but with the bike laying down and use my weight to turn it , it works
mine is exactly the same i gave up put seat back on ,seeing your vid makes me want to have another crack at it fool that i am.
I got a Fuji bike frame that had been sitting outside for a while and I soaked it in PB blaster for a few days, heated it with a torch and quenched it with PB and it came loose with a pipe wrench.
haha it worked with the hot water !!!! thank you sir ;)
Just purchased a used Giant with this issue. Oh boy it looks like it’s going to take me more time and effort than the bike is worth lol. Great video thank you.
th-cam.com/video/S3ek2GeZzE0/w-d-xo.html
Well done!!!
had the same problem with a road bike and i took the bottom bracket off and i've filled the tube with vinegar with the bike upside down, also you can pour the penetrating oil or vinegar tru the cup holder screws if u don't want to take the bottom bracket off .. and used an adjustable wrench on the top of the stem so I can reuse it!
Then your seatpost was not seriously stuck.
This video actually helped
Thanks for watching Bobby!
I love how we go from WD40 to heat to Defcon 5, to into the trash after a while!!!
I have the same problem right now hope it works well for me
Wow that was incredibly stubborn :-o
That was epic! I had a problem getting a seat post out of a early 80's BSA 10 speed. It was a chrome steel post into a steel frame, not too rusty either. The damn thing would move up and down, but i could not get it out. After much lubrication and brute force it came out. Turned out that there was a small burr in the frame. I put that right with a file. Great video!
I just did the same on a Raleigh mountain bike. took me and to guys. few pointers. . have someone pull up on seat while turning with the pipe wrench. 2. Continue turning in the same direction after it breaks free (also while lifting up). 3. Heat the frame, maybe dry ice the seat post but overall steps 1 and 2 are critical to keep it moving out. add lube anytime you can.
"Eh, that's a wasted effort." I LOVE IT !!!
