How To Remove Stuck Seatpost In Minutes With Slide Hammer

I show how to remove a seized seatpost from a bike frame using a 10lb slide hammer. I borrowed the slide hammer from a local auto parts store after paying a deposit. Be sure to get a 10lb slide hammer as I don't think a 5lb slide hammer will deliver enough force. The aluminum seat post was likely frozen in the steel frame due to galvanic corrosion. I had been spraying it liberally with Kano Kroil penetrating oil. I manged to unstick the seatpost in just a couple minutes. You may need to connect the slide hammer to the seat post in a different manner. Possibly drilling a hole through the side of the seatpost and attaching a chain on each side with a bolt going through the post. Or whatever works for your situation. It only took a couple minutes for me to remove the seapost. Now I can repair the bike. Your results may vary.

23 wacks not bad💯✊🏾💥

[@darrencady4261]

Galvanic corrosion is real. But to utilise a slide hammer to overcome a seized seatpost is an idea that's simple once you're seen it done. It's thinking up the idea that's the difficult part and that is where you prove yourself again as not only a brilliant mechanic but one with original ideas, improvising a solution to a specific problem. Many thanks for a great presentation.

[@rodenreyes6320]

Those bike companies should be doing this for us while designing better seatposts or metallurgy.

[@lucianonarno1408]

Great method! No damage to the frame or any other parts. Big thumbs up for this one RJ.

[@stevent5050]

Great job, RJ!! That has to be one of the quickest seized seatpost removals ever.

[@kingfiredude]

I like it no heat, cold, vinegar, drain cleaner, acids, and all that other stuff

[@samroberts5114]

I would just like to say how grateful I am for this video, thank you very much. I had a well and truly stuck seatpost, I'd tried everything else (other than caustic soda) and was about to give up hope. I had never even heard of a slide hammer until this video. I ordered one online, tried it and pop, out came the seatpost. Unbelievably simple but effective method.

[@thersten]

I noticed how your energy shot up. I do the same thing when I'm triumphant.That's why I like to repair things too. good job!

[@jmelewis]

Just wanted to say THIS WORKS!! Had a stuck seatpost that nothing at all would move. So bought a slide hammer second hand off ebay for £12. Did exactly as in the video, and after a while it freed it. Thank you so much!

[@WaterHartwellWhite]

Which slide hammer because I am looking for eBay and I can’t see one with an attachment that looks like it will work for the seat post. If you can find it, could you let me copy the link?

[@MikeBaxterABC]

This is one of the best methods I have seen! ... the main point being it saves a seat post and the frame with no damage, not even painting needed ... AND it's fast! :)

[@guskoerner75]

I've watched several of your stuck seat post methods, and by far this one is the best and the one I am going to try! Thank you. I own 6 family bikes, and I'm going to pull all of them, polish the holes and the stems, and put them back together with anti-seize. With proper preventive maintenance (PM) this can be prevented. Thanks again. - gus

[@bhugeloo95]

this felt so satisfying !

[@danieldaszreen9182]

Bhugeloo95 i know right 😂

[@monkrph]

Boogie nights

[@dannyr333]

So satisfying

[@Chris-ny8hv]

This worked for me! Only had access to 5lb hammer so took about 20min of hard work, but it WORKED! Thank you!

[@WaterHartwellWhite]

How do you attach to the seat post?

[@Ronin_Texas]

Hey RJ, this video really impresses me , i have to fight many stuck seat post in my 20 years turning wrenches and I never imagine such and ingenious way to do it. Thanks a lot for this video. two thumbs way up.

[@mingwon3082]

Wow, just seeing this for the first time as I have the same problem on my bike! Never heard of a slide hammer until I watched your video! Thanks for sharing 😊

[@pozr4530]

OMG 10 years ago, I had the same problem. I tried icing my seat post, heating my seat tube, prying open my seat tube opening w/ screwdriver and hammer, all kinds of lube-oil, light grease, WD40, etc. Nothing worked. I didn't try Draino or vicing my seat because I didn't want to destroy my saddle or destroy my frame's paint anymore. I ended up riding it as is. I didn't have that great tool or Kano Kroil penetrating oil. You are brilliant!!!!

[@MustYouHaveAUsername]

Damn cross-fit workouts are getting crazier every day 😅 Joking aside this video has been helpful for a buddy of mine with the same issue years after upload, so thank you very much!

[@tomshiba51]

After watching one of your videos where you had to destroy the seat post, it was nice to see this seat post come out without the need to drill, cut, or mutilate.

[@NUNU37]

this also the reason I lightly grease the post of every bike I ever touch (excluding carbon) It's like my gift to humanity lol

[@RixterNow]

Impressive! I had a stuck aluminum post in aluminum frame. The LBS could do whatever they deemed necessary. They drilled a hole in seat post, put long carriage bolt through. One guy held bolt, another turned the frame. Seat post did come out. 2 person job though

[@nowthenad3286]

I have never heard of a slide hammer. Fantastic idea.

[@Pawelism]

Every time you start with 'Hey Viewers' I heard 'Hey Dears!'. Thanks for doing these videos - they are great!

[@KevinCarney]

EPIC CONCLUSION!! You're panting through your subscription plug. lol. And the moment it actually comes out.... most satisfying thing ever.

[@bigd835]

These kind of videos are extremely helpful. Thank you for sharing. its in my memory forever.

[@y2fmc]

Nice work RJ. You've earned yourself a Pepsi :P

[@robinwas-miles4641]

The main task is to break the corrosive crud between frame and pillar. The vibration alone is probably part of the success and pull hammer effect deals with the extraction process. Must be the safest, least expensive, least destructive way to win out.

[@primarulgiurgiului]

I love how happy you are when you finish such a job. It almost makes me satisfied! Great job!

[@tad2ik]

I spent days fuffing about with stuck seatpost. If only iknew about sliding hammer. Thank you

[@crumplezone1]

Who needs MC Hammer when you got RJ Hammer :) good work man

[@michaelkirwan177]

Although it involves a tad bit more prep and should the Morgan Hammer not budge the seat pipe it might be worth removing the crank-set and inverting the bike then "Liquid Wrench" the lower end of the galvanic adhesion so as to facilitate removal with less actual trauma to the seat mount assembly. With something less viscous like Liquid Wrench the added saturation greatly enhances the friction reduction component of the problem. By giving the bike a gravitational edge for the fluids propensity to run down hill once the two fluid levels meet a simple twist will often do the trick. The galvanic response can be mitigated to some degree by rotating the bike from inverted to upright and vise versa a few times with an occasional gentle tapping of the exterior of the seat tube with a rawhide mallet. More time consuming and perfect for overnight soak times when feasible. A hair dryer, or heat gun on low would also enhance the likelihood of success whilst lessening damage potential.

[@freemoneyforahome]

It worked for me thanks - after about 20 hits it unfroze and a pipe wrench twisted it out

[@KowalskiVanishing_Point]

Frickin great video as I have a seized thud buster seatpost in my Salsa Fargo.

[@hernanyteles]

Also happened to me but in the aluminum frame and the carbon tube. I put wd40 between the tube and the aluminum frame (enough) to let it absorb and then fastening the frame and turning the seat it released. After taking off, I cleaned and re-lubricated both the carbon tube and inside the frame with wd40 and it was perfect. There was no need to cut or break anything.

[@BSS22193]

Great video as always. 👍 I'm going to try out two of your methods on my steel frame BMX bike with an alu seatpost that is completely stuck tomorrow. First i'm gonna try this method with my slide hammer if that dosn't work i'm going to go for one of your other methods using my impact gun to get it loose.

[@domgdesign299]

I've had a few bikes with this issue. Seriously frustrating. Well done with this.

[@HDsharp]

Wow look at all that rust, and it still popped out, great stuff.

[@PrabuddhaDasGupta1966]

I have two frames with this problem. The twist method did not work mainly because I was scared of putting too much pressure. This method will most likely not damage the alignment of the frame. I shall try this and see. Thanks for the idea.

[@leqin]

Well there is no argeument is there... RJ is 101% commited to the job and, the last video I watched on the tube trying to budge a stuck seat, they spent a edited 30 minutes failing. Thanks RJ.

[@wheeleyguy]

Great Job! Ingenious solution to an all to common problem......Thank You!

[@njm3211]

Man RJ you need to stop buying these junkers at your local flee market. Hope you are you fixing them up for a good cause😂 Bravo for using slide hammer. Was afraid you weren't pulling in line with the tube but were offset by the seat clamping mechanism. But it worked.

[@chiangui24]

Your reaction at the end is the best thing I've seen all week

[@jerryavalos9610]

Good job. You worked you back end off on that one. This would also possibly work on a stuck quill stem.

[@dylankennedy8140]

Brilliantly done. Useful and very entertaining.

[@mochamadmulki7615]

that must be very exhausting. love how you do lots of method to fix seized stems & seatposts. thx for sharing 👍🙏

[@fernandogopro]

GREAT idea mate, thank you very much for sharing

[@gc5643]

Great video, thank you for this. I have been looking for a sotution and brute force succeeded.

[@med10n]

i had a seat post that was really stuck tight, felt like it was welded. went to numerous hire & hardware shops. they never heard of a slide hammer. i had to describe to each what it was & what i wanted it for. must be only available in the USA. i gave up & tried heating/cooling down the post. worked perfectly with a pipe on a wrench & no paint damage... you must have a garage full of bikes ....

[@RJTheBikeGuy]

+med10n It's a tool commonly used in car repair shops. For pulling bearings, pulleys, or pulling out body dents.

[@mtlnascarfan]

Perseverance pays off!

[@miorieser3210]

So geht`s auch bei Backenzähnen! Super.

[@ReclusiveMountainMan]

Slide hammers are great! Congrats on getting that post out! You owned it!

[@gamerdude0]

Neat solution, I will bear it in mind if I ever have a stuck seat post. Thanks.

[@TheRenolero1]

RJ always Beats stuck posts.bin every posible way. Love seeing and Learning from It ☺

[@RJTheBikeGuy]

I love the challenge. Did you see my impact wrench vs seatpost video?

[@pentuprager6225]

I had the answer to my problem. Thank you. Knowing about proper tools is important.

[@budchestnut9303]

Remove the crank axle first and invert the bike and spray Croil, WD40 or Blaster in the seat tube to get it to the bottom of the post. It will brake free easier.

[@stevesimmons6685]

The best of all solutions and no marring!

[@dblaps]

man I wish I had a garage like you. I live in a top floor flat where I have neighbors all around with the worst sound proofing ever. I wish I had somewhere where I could crash and bang while working on my bikes. One day!

[@crazycraigy01]

same, I live in a rabbit hutch.......

[@danpisula3531]

I have a stuck seat post on Burley Tandem,I am going to try this method. Thanks for the informative video.

[@TheBRad704]

New bike day for me... means a trip to RJ's channel for help. :\

[@RJTheBikeGuy]

Fun!

[@RobBastien]

WoW! That's a good tip. For a minute there I was going to suggest to take it easy and have a Pepsi break...but "Bam" it came out. But keep those cases handy, you never know.

[@Jeanboglietti]

Man I"m so happy you managed to take this off! I can relate

[@rixretros]

Great Idea, RJ !!! BTW, if you want to use a good penetrating oil, use either Seafoam Deep Creep or Liquid Wrench penetrating oil with the yellow label. Check out testing of penetrating oils on the Project Farm channel on YT. That guy know his stuff....and shows you the evidence. I prefer the Liquid Wrench stuff myself and have used it for years. It came in #2 on the Project Farm tests.

[@RJTheBikeGuy]

I have probably seem them.

[@stevejeffries1603]

That was another success.

[@timsmith9758]

Good job.... I'll try it now....slide hammer....never heard of one

[@6ryba6]

Now that is a gamechanger

[@jimmymal]

A W E S O M E. great thinking, and thank you for sharing. 10 THUMBS UP!!!!

[@greg1268]

I’m hitting the auto parts store this weekend! I have a ‘62 Schwinn racer and that seat post is STUCK!!!

[@hookerjl1]

You got it...well done😃😎i will keep it in mind!👍🏻

[@adrianoadriano4730]

great job guy 👍

[@eruetifoster5162]

It sounds like you got a good cardio workout too. This might be the genesis of the next fitness craze to sweep the world.

[@rezjrprod]

This worked for me! Got wd40 penetrating spray and to big knocks it was out

[@zhen86]

A great workout

[@frannelk]

This technique is very clever 👏👏👏👏

[@jeffbrunton3291]

First time I have seen this technique, and I have looked all over to remove seat posts. Excellent job. I really did not think it would come out - I realise the direction is good, but I thought some twisting would be necessary to break the bond. Do you think this is the best method for posts that are stuck the worst?

[@RJTheBikeGuy]

With this method, and movement is in the direction you want to go. Out. It's always worth a shot.

[@robertmihalyfi4901]

It was so satisfying to see it actually moved. I was not so lucky about a year ago. I've had a same type of seatpost, but it doesn't came out. We used chain hoist, rubber mallet, we heated it cooled it, and finally we pulled out the head of this seatpost from the actual tube. (the tube doesn't moved a hair). Then we lost the mounting hole, so we drilled one on the seat tube. (It was out about 1 1/2 inch) AND we managed to tear out this holle as well! At the end we unfortunately ruined the frame.

[@RJTheBikeGuy]

+Robert Mihályfi I would have loved to have a go at that. I think I could have gotten it out without ruining the frame.

[@robertmihalyfi4901]

+RJ The Bike Guy Well it was a good lession after all. Next time I will be more patient, and much more gentle.

[@RJTheBikeGuy]

In this case, I can clean up and reuse the post. If it hadn't come out, I would have tried something. I would have sacrificed the post to spare the frame. I could have dissolved the post with drain cleaner (lye) which eats aluminum but won't hurt steel.

[@robertmihalyfi4901]

+RJ The Bike Guy I didn't even thaught about the chemical aproach. This is another good idea, thanks for that!

[@drmodestoesq]

This was way more satisfying to watch than those blackhead removal videos.

[@user-xu5uc6oz9d]

Great idea! Thanks for sharing it.

[@battistaverardi1240]

Oh nice! I may have to try this although I have a carbon fibre seat post into a 7005 aluminum frame and it’s literally welded in there but I’m going to try this.

[@chaichotechanchiew3155]

Good job!

[@christippett8581]

I love the sound of a slide hammer in the morning -lol

[@OmaBike]

I find these stuck "post" videos really interesting.

[@RJTheBikeGuy]

Me too!

[@lionden4]

You’re a legend!

[@ramiansyamal]

Good job 👍

[@williamensign1408]

I think that should work on handle stem. Great idea, thanks.

[@RJTheBikeGuy]

The problem is all that force would be going into the headset bearings.

[@Sooperhans3636]

RJ, you never disappoint!

[@AspectRatioPolice]

Best Method so far.

[@sm870621345]

Those seat posts are the bane of your existence, hey? haha Good job!

[@marloncabintoy4592]

Good job rj.. ☺

[@honda200twinstar3]

Lol i had a nice GT mountain bike with the same dam seat post .had it on the bike stand upside down .had the vice grips on it and hammered on the vice grips down ,and usually if its going to work thats how its going to work ,but not this time ,i hammered and hammered to no avail ,then the cradle seat portion popped out .then i hammered down (bike right side up on the floor ) hoping it would move down then i could hammer it up but again to no avail, of course by this time the post was pretty much mangled ..so then i had to move on to making slices in the post to try and twist the pieces ,then i had to move on to grinding it ..i had to get a drill exstention to put my grinding bit on ,my hope or plan was to grind it right down passed the fused section then i might be able to use another post to hit it ,knock it down .then i used a hock of sorts (your slide hammer might have worked here.)to bring the rest of it up . So it only took me 3 days of hammering and cutting and grinding but i got that 3'' bastard out lol . Man i just cant understand why they put an aluminum seat post in a steal frame ..tale about your chemical reactions

[@Albanez39]

Aluminum parts on steel frame are the standard. Aluminum is a very light and very strong metal that works great for small parts, tubes and similar components. Nowadays aluminum has been replaced by carbon or titanium in the professional peloton, but it's still the most used metal for such parts. As for the frame, aluminum is not a good metal in my opinion. Light and sturdy, but uncomfortable and not fixable. Steel frames are very elastic, can be welded anywhere, by anyone, for a cheap price and steel still is one of the strongest alloys out there. Steel frame, aluminum components make for a great bike that doesn't cost a fortune and lasts decades...

[@kevinsmith9836]

Well, it worked, but that looks exhausting. I was reminded of the crushing discouragement of a pull-start tool that won't start. Nonetheless very impressive!

[@f4e621]

I would use adjustable wrench or pipe wrench to rotate it first.

[@RJTheBikeGuy]

+g rg Here any movement is movement in the right direction.

[@ramskrall]

That’s the best way I’ve ever seen it done 👍👍👍👍👍👍

[@RJTheBikeGuy]

kzbin.info/www/bejne/hl68oaB6rZ1pmpI

[@Maik1968]

These parts as well as a seized stem or bottom bracket can sometimes take you hours to get them lose. On the other hand kind of aggression treatment ✌️😎💪🌞have such a patient in my vise right now. We’ll see who wins the game 🤣

[@Joaoguica]

It was an hard job !

[@jerryquintana2508]

Going to give this a try thanks

[@NugeFireball]

Wish I had seen that 2 years ago! My 94 GT Timberline had a frozen seat post, I tried a bunch of things, ended up hacking at it to try and peal it out from the inside and basically ruined the bike.

[@kiranjshedge]

Good Workout 😂👌👌👌

[@FS-wd3hu]

I'm gonna try this

[@abj14u2c]

so happy for u right now

[@orangestoneface]

slide hammer cold be homemade from pipe and well here l have weightlifting weights that fit around a pipe , or tape some heavy bolts in a circle or anything heavy, , og might try to beat on the end to push seatpost down first to get movement, or just remove top piece on pipe and put a thinner seatpost inside old pipe and cut a slit in old to put a fastener clamp around.

[@shafi420]

I was thinking of doing that. You have shown me that it does work

[@davidrogers7137]

I was so hoping this would solve my problem. Trek 520. Less than 3yrs old. Post stuck. Currently going into second hour with 10lb slider. 15-20 whacks every few minutes. 😡

[@stevejeffries1603]

Interesting Never seen or heard of a slide hammer b4
