- In this video we remove the worst stuck seatpost I have ever seen. It did not look that bad at first but things escalate once we start to try to remove the post. Tools required are oil, determination, hacksaw blade, blood and sweat and If all else fails...... Some adjustable reamers from Chadwick & Trefethen, INC.

Stubborn man meets stubborn seatpost. Nice job there 👍
Your video is the only one that mentions/ demonstrates this inexpensive reamer tool. Your comment, “19 out 20 stuck posts aren’t so bad” or similar motivated me to give my stuck seat post another go, bike upside down in a vice. Using ATF & Acetone 50/50 mix as penetrating oil. It let go with a loud metallic sound! Followed by more penetrating fluid, 20 min soaking, repeat, repeat. Until out. Happy days. Thank you for sharing, it helped. Best wishes.
Goodluck👍
Great video, had the same problem. Great job
Thanks for the upload/great instructions. This was one of the worst things I think I ever had to do, had tried everything you mentioned like letting it soak for days, making a mark and banging on it with a hammer, trying to cut slits in it.. it was an aluminum post in a steel frame, I guess some special kind of corrosion can happen there. Went searching online every day, finally found a random post by someone who said they had stuck the bike upside down in a sewage drain (I guess also with a rod through the post). Put it upside down in the vise with a rod through it, and like magic it started moving. I don't think I would have ever gotten the idea with the reamer, will keep that in mind but hopefully won't need it! :) Glad you finally got it removed
I'm glad you got it out. Putting a rod in the post and putting it in a vice was half way through the video. That was when the post was so stuck that it was twisting. The video was supposed to show how easy it was to remove a stuck seat post but turned into a nightmare. I already put too much time in the video and I was going to get it that is when I thought of the reamer. Thanks. I'm glad you got it out.
@@alloutbikes Thank you for the reply! I did watch the full video, found the channel through the hoarder house cleanup and was looking through some older posts. It just reminded me of when I had to do this, which was a few years ago before this video was posted, and I can certainly identify with 'nightmare' :) Wish I had found it then. Even if it didn't turn out as planned it should help people out alot to see all the steps you went through, ultimately getting it out with the reamer. Cheers!
Thanks!
I just removed a stuck aluminum seat post from a steel frame. Post was so stuck the clamp inside the post started twisting from the force I put on it when twisting. Squirted WD40 around the post left it 24 hours, reapplying a few times.
I then took the saddle off and turned the bike upside down and put the seat post in a bucket of iced water, half filled with ice, topped up with cold water. Left this for about an hour until the post was very cold. Turned the bike over again and held a piece of wood on the top of the post, hit it hard with a hammer and the post slipped down after 2 hits and I could remove it easily.
I think ill just buy a new bike!
The owner only wanted his tire pressure checked!
With those shades J, you look ready to attend a Sublime concert.
Wow, awesome job! Thanks for posting the helpful video! I'm currently wrestling with a seatpost myself and just ordered a reamer set to try and do the same thing. I'll try to stop by the shop next summer when I'm heading down 95 to the beach. Cheers!
Very good job! How much does such a mission cost?
yer have had a few rough jobs with seat posts but never that bad well done getting it out and your right have always managed with the vice technique. Good point putting the shim in to prevent vice crushing the post to much. Helpful video.
Thank you. The video started because I wanted to show how easy it was to remove a stuck seatpost. Little did I know it was going to be the toughest seatpost in my life!
Insane effort here. I am definitely just throwing the bike out haha
The reason I went through so much effort is because the customer brought in the bike for a tune up. He didn't tell me he just bought the bike. I tuned the bike up with new cables and parts. I noticed the stuck post when I was doing the tune.The bill was about $189. When he came to pick the bike up he needed the post raised and didn't want to pay for it if the bike was going to be small. That is how it started.👍
Let that be a lesson to us all: Add an annual removal and lubrication of the seatpost to our regular preventive maintenance. 👍😏
Wow man ,,,you really worked it out...extraordinay .....you give me hope because my is .as welded as your in my KHS ,and l don´ t know where to find a tool in size like that... .great👽
wow that's some great customer service
My local bike shop would have been like "We got your seatpost out. Here's your 600 dollar charge in labor for your 80 dollar bike" 🤣
At that point it wasn't about the money. It was personal......
funny coincident? my stucking seat post is also stuck into a GIANT!
WOW! What a job that was! LIke you, I've also been in the bike industry for a long time (30 years). Quite often before putting the seatpost/bike in a vise, I will use MAP gas and heat the seat tuble/seatpost and have had good luck with that. My last bike that i had an issue was a 1950's bike that had been left outside in the winters in Maine for 55 years! Obviously with a bike being in the weather like that, nothing was working. So I took the bike to a local welder and he used his torch and it did come out. It also took a tad of paint off as well, but then again after 55 years outside... it didn't have a lot of paint left. HA! It seems that quite often a bike that isn't worth a whole lot costs shop more money in labor/time than what the bike is worth. Thanks for sharing!
29 years for me. The customer didn't want the paint damaged. The video started because I wanted to show how easy it was to remove a stuck post. It turned into a nightmare.😣
@@alloutbikes I HATE those projects, but they certainly do happen. I've never had paint issues with using MAP gas, but of course the torch did take some off..but the fact that bike was outside for so long, it had a lot of paint missing.
how about drilling out a post? I have mangled schwinn post that's been banged in chunks (hacksawed it) into the frame (curled in).. seems like drilling is the only way for me
@@RagedContinuum The MAP gas is quite a bit quicker, than drilling it out. I've never had to drill one out, but I've seen others do it, and it seems to take quite a bit longer. But if it works for you that's great.
Jesuz, hardest stuck seatpost on youtube! Maybe in the history of bikes tbh.
Yep. That was the hardest one I have ever had.
Happy Thanksgiving Jason to you and all your family. Thanks for showing this :) Live Long and Prosper!
Now I know that mine will never come out
ha ha ha ha l know the same....life is so hard some times👽
The whole time I was watching I kept thinking that anytime soon Ashton Kutcher would jump out and tell you that you were being punked.
Something I didn't see you try was heat, it may have helped the penetration of the oil, also the different metals expand at different rates which can break the bond.
Theres also the muriatic acid trick, plug the saddle end of the post, turn the bike upside down and fill the seat tube with muriatic acid and wait, the acid eats aluminium but not steel. Aluminium and steel have never been good friends and a coat of grease helps a lot.
The customer didn't want the paint damaged in anyway. Next time I may try the acid trick. Thanks!👍
@@alloutbikes Hope, he paid your extra work ;-). Great job anyway.
Great content so far keep it up 👍
I was getting pretty worried for a while
Great video. What adjustable reamer did you use specifically? Just went to the Chadwick website and there are quite a few listed there. Thanks in advance.
I'm wondering the same thing 👀
Great job, thanks for making the video! I’m struggling with a customers bike and the reamer idea came to mind so I checked TH-cam to see if it’d been done, that’s how I got here. Anyway, do you have some details on the reamer you got or a link to where I can find it? I found a few options online but it’s be nice to get one I know will work. Thanks for any help you can provide!
Thank you for this.
No. Thank you for your comment.
Yesssssssss!🤘
I've got a real bugger here! The post is aluminum on a 1984 Schwinn Sierra. After finally deciding to cut off the top to Sawzall some slits I find the post is almost completely solid aluminum. Only a hole the size of a sweet pea down the center. I saw RJ the Bike Guy drill a hole through an impact socket and the seat post and use a big impact drill. That's my next step but drilling through the impact socket has been time consuming. I also saw a guy using costic acid to devolve the aluminum so that might be an option. I tried the vice but it didn't work.
I haven't tried this yet but I know from a mishap that oven cleaner eats aluminum and seems to not harm steel. If you put a cork in the top of the post and turn the frame upside down and empty the can into the seat tube that might help. Keep in mind I haven't tried it. Goodluck cause I'm telling you its not going to be easy.
Ended up spinning it with a big hammer drill and getting it out with a big rotary chipping hammer. I put up a short video to help anyone with power tools
I thought the truck was more likely to flip over than the seat post move.
Your not kidding. This video was supposed to show you how easy removing a stuck post was but I had to pick the most stuck seat post in history! Thanks for watching!
you can make your own penetrating lubricate oil that I seen on TH-cam. Make your own with 50% automatic transmission oil and %50 acetone. It works well and cheaper than PT Blaster. You had a difficult job with that seat post. Do not reverse the expansion reamer, always rotate in clock wise direction, even when you are removing it out of the hole. Good luck, great video.
Thanks!👍 I have been told how to make my own penetrent before but I forgot how. Plus this post wasn't supposed to be this bad. I had to pick the most ridiculously stuck post in the history of bikes to do a video on. It was supposed to be a how to easily remove a stuck post not how to waste two days worth of your time! Thanks for commenting.🖖
Goo job but still looking for an easier way to i this :) thank you
This by far was the worst seat post I have ever run into. I have never gotten past the clamping the seat post in the vice before. Sorry. I had to cut one post out but all the others I put into a vice and just worked the frame. I would be surprised if you had to go further. Just remember to use plenty of oil. Thanks! Good luck.
I just purchased a surly pugsley with a stuck seatpost I have tried everything I just ended up cutting it down an inch shorter and then I'll put the seat on hopefully good enough.
That may not work. The bike most likely has a seatpost with an integrated clamp. If you cut the head of the post you will have a hard time attaching the seat. On the other hand if the post comes out of the frame but only goes in a certain amount then you can cut it as long as the seat post goes in roughly four inches. A railed seat clamp only works for 7/8 or 22.2 mm sizes and the pugsley post has a larger diameter then that. I hope all goes well. Thanks for watching!👍
i've heard that sodium hydroxide melts aluminum saving steel / iron. Maybe can be another solution?
Where has that been stored?!? I got a bike from my grandpa that was sitting in a shed and completely rusted, the seatpost on that came lose with some lube.
The bike looked great. There was very little rust.
0:28 Please, tell us why WD-40 should not be used, even when it’s the only thing you have. What future problems can come from using WD-40?
Sorry. I should have been more clear. WD40 would work as a penetrating oil It has some really good cleaning properties. In this case we don't want the cleaning properties WD40 provides. It doesn't protect the metal from rusting as well as other products. WD40 evaporates easily and washes off with water. If you do use WD40 you just need to clean the frame and add something that will protect the metal after your done. I have also had less luck using WD40 to free up frozen parts compared to brands like PB Blaster. Goodluck 👍
My problem has been bent seatposts they dont want to move
I have had a couple of those but they always came out fairly easily.
If you have an alloy frame and alloy seat post will rocking the bike on a vice damage the frame?
In most cases it will not damage the frame. The post will get damaged first.
Three hours later and a lot of sweat and my seat post is finally out. All to make a 1/4" adjustment in saddle height. It has taught me to check if the post is frozen on any used bike I consider. Never again, I say!
Your not kidding! Thanks for the comment.
Your video was very helpful and motivated me to not give up after seeing your struggles. Thanks!
Don't bother greasing the new post. How could lightning strike twice in the same place? lol ...
Trust me it can. Thanks👍
Steel on steel stuck post 12 inches down into the frame for going on 40 years now. You think this punny aluminum post was stuck😅
My condolences to you sir. Only 2 ways for that lots of penetrating oil and lots of elbow grease. If that doesn't work it time for some heat. Goodluck sir.
@@alloutbikes Thanks. working on your method. Wont be ableto drill it out. Patience.
Came out real easy in the end. Penetrating oil and atf for a day . Air hammer in a bit to break the bond. Big pipe wrench and out it came. The air hammer made the difference. Guess my problem post was the punny one in the end.
Bike companies, redesign ancient seatpost/frame joint ...we are compeling you.Or we are dumping your bikes and go into backpack rockets transport/sport.
I used 50 50.ATF and Acetone for penetrating oil on a outboardmotor tilt shaft which was badly seized. That worked better than any store bought fluid. Try that on your next seat post. The air hammer to break the bond for the win.
,i got my hands on a Cannondale F1000 wth a snapped post.. I can't wait till I get to actually ride it!!😣
I hope you have no problem removing the post. Thanks👍
After cutting socket type slide hammer??
I had many ideas. It just ended up the way it did due to how things played out.
Lesson learned - don’t use Gorilla Glue in the first place!
Just ask the you tubers watching to hold things for you.
Why didn't you mention that earlier. Thanks for watching!
Do they rent that tool out? Very pricey for maybe a one time deal. Lol
No rental. Luckily since I work at a bike shop I can recoup the costs. Eventually........
It could take.............some............................time...............🕛🕐🕑🕒🕓🕔🕕
Some say that Jason is still trying to get that seatpost out of the frame to this day.
Just found.
Boil water poor on frame expansion??
I was thinking about that while plugging up the bottom of the post and putting dry ice into the seatpost. Never happened.
O only want to know if the customer paid the massive amount you deserve?
No. It became personal. Me and that darn bike! I was not going to be beat by a stupid seatpost. Thanks for posting..... no pun intended.
Or bring bike to a machine shop and pay to have it reamed out if all else fails.
The problem with having it reamed out is you have two similar metals. You can't tell when you cut through the post and into the frame. With the Giant bike I was working on. It was an alloy post which was a soft metal and I could feel it it the frame that was a harder metal. Good luck on getting your post out.👍
Ammonia, or lye, or even Cocoa Cola should dissolve the post. Sectioning it out should not be necessary.
The problem was penetration. The post should not have been that stuck. I have removed close to a hundred stuck posts with no problem. On this I used a little heat (not on video). I used lots of penetrating lube with no effect. After I was knee deep in it it was to late to try other things. Of course its easy to say what I should've done afterwards. But I have never run into a post this fused to the frame. After all was done the penetrating oil barely made it into the frame. Keep in mind this was The Post from My Nightmares. It should have been easier. The video was supposed to be (How to easily remove a stuck seatpost) Oh well. Thanks for contributing.
ever try 40 percent vinegar;if you do send notification
Yes, but I haven't had good luck using it on stuck seatposts. It's great for getting rust off parts.
Vorrei che la spiegazione sia in italiano
U literally hand drilled out a seatpost
Bro this might be what I'm needa doo.... Tomorrow I will come on here and let u know if my seatpost got removed prior to the drilling
I loctited my seatpost a couple yrs ago cuz I'm dumb. It's a carbon fiber. I'm letting wd soak over night from the bottle cage access as well from the top... I have wd, breaker bars, sledge hammers, pipe wrenches, gloves, and some perservence.... It will get removed!
I wish you luck. Cutting out the seat post is not fun. I think you might be OK because carbon cuts so easily. It will not work if its in a carbon frame. Its got to be a softer seat post going into a harder frame otherwise you cut the frame as well. Goodluck and Thanks!
@@alloutbikes hey my dude thanks for reply.
Well I'm in FL its 230. I started at 1130.
So I had to go in there like u did. I had bits from my dad tools he worked body shop for yrs and yrs.
I have it so a seat post can go about 3 inches into the frame. But there still carbon stuck to the frame down there i cant get out. I was shaving carbon ounce by ounce and the fibers I never worked with carbon except sawing a frame head post but there very very splintery
When I first started today I used no gloves than I cut my finger with exacto blade wore gloves but I feel little splinters in parts of my hand. Dude the worst thing that happened happened. Same as u. I didnt do a perfect job but about 85 percent i feel if a person put some blue loctite not red like i dumb dumb did. It shouldn't have issued of be worried about a seat post fail mid ride.
I mean if a seat post can go 3 inches into the frame that shuld be okay? What ur thot?
Alls I know that sucked. But I feel pretty good about how it is now.
Lmk what ya think
Peace dude
I am saying someone need to put a seat post on this frame is cuz only reason why I needed to get seat post removed is cuz I'm gonna sell the frame it's a caad 10 58cm if u know anyone looking for these bad boys let me know... but yeah I'm think about the next owner cuz I even told myself keep going further down for if I felt safe riding it also. I felt how far down (the broke seatpost) I had I used to.slide down in it
I felt like it would be more than safe or suffice
The time it has taken to do this job, means the cost is probably double what the customer paid for the bike! Silly light duty vices are of no use for this job, and penetrating oils wont help when parts are stuck due to galvanic corrosion,
No. I charged $50 for the job. There was no chance I was going to be beat by a stupid seatpost. It normally is no problem. I quoted no more then $50 due to past experience. This is by far the worst stuck post. It was personal at that point.
@@alloutbikes Yes I can understand that. With a heavy-duty vice, and a steel bar that fitted inside the post exactly, to clamp onto, it would have probably come out much easier?
@@humourless682 Nope. I put a socket inside the post and tightened the living daylights out of it and the post actually twisted but didn't break free. I have never seen a post twist like that. But thanks for your ideas. I already tried it before going through that mess.👍
@@alloutbikes I get the feeling that some sort of fixture that would securely attach to a stuck seat post, which a slide hammer attached to it, would work very well? Also working out the best thing to soften the galvanic corrosion, and leaving that to soak in overnight, would be useful.
How much is he charging for this? $1000
I charged him $50 as a favor for letting me use his bike to show how easy it is to remove a stick seatpost. By the time I figured it was more then the normal stuck seatpost I was not going to give up. $250 for tool minus $50 I got for the work $200 in the hole and 6 hours editing the video (Priceless). At least I still have the tools for next time I need it. Thanks for watching!

You forgot to calculate the sweat and back and arm pain! I had to go this route once to remove a seatpost - never again!

RUST SUCKS!!! WHY NOT USE HEAT TO TAKE OUT THE POST???
Because I didn't want to damage the paint for the customer.
@@alloutbikes Three more tricks to make this work before drilling it out with an obscure tool:
1: Use a soldering torch (~3300°F) to heat the post above the frame (so the paint is safe), and a large bucket of very cold water to cool it down afterward. The expansion from heat and sudden shrinkage from coldness should break the bond between the iron and the aluminium oxide.
2: With the bike upside-down, poor vinegar in the frame to dissolve the aluminium oxide.
3. Use a pipe wrench on the seatpost and a ratchet lashing from the end of that to the steering stem. This way you can continuously pull with a massive force (600+ lbs) and still have your hands free for a 10 lbs hammer to also hit the pipe wrench with.
Also the thermal expansion coefficient of aluminum is 2.5x steel so heat will only make it more stuck
@@hughpatterson5048 The cold water afterwards is essential and really does the trick.
alum expands more than steel exacerbating the problem
Someone had to have put a bigger tube on there than stock.
No it happens all the time, alum post steel frame
It probably doesn't matter, but just fyi, someone can get you address from you neighbors plates. Wouldn't matter unless some pyscho cares.... 🧐
You can get my address from the business. There is only one All Out Bikes in the world.
All that time and effort for a 10 dollar bike...🤦🏻♂️
All that effort because I told him that I would have (no problem)....(I do this all the time). I do this all the time it's just I had to pick the worst bike of all time to video. If I wasn't doing a video I may have told him that it was stuck. Also it really got under my skin. It kinda got personal. I don't know exactly the reasons. I just hope I never run into this again. This was the first in 29 years like this. Thanks for commenting.👍
It's the wrong size seat post. Meaning that post is a couple of hairs bigger then it's suppose to be. It slides in, but gets stuck immediately..
No. It was the right post. A chunk came out that said 30.2 and that is the proper size. You sould remove your post every year or so to clean and grease it. Thanks for watching.
@@alloutbikes I started putting a thin layer of antiseize on my posts, but yes you are correct taking it out would be a good idea.
