- I show how to take apart, clean, lube and put back together a rear bike derailleur. The derailleur I used in the video is a Shimano RD-5600 road bike derailleur. Other derailleurs will be similar, but may have differences, especially where removing the cage from the main derailleur body.

How to re-assemble the pivot bolt and spring starting at 13 minutes was a “life saver”. Thank you!
I used to watch shows like game of thrones and westworld, now I just watch this channel. EPIC
thats so sad mate. Dont you do anything yourself but watch other people doing stuff?
Amen! 😁
hahahaha right
i wish i had an uncle like you and together we would take apart all the bike parts all day long. instead i'm watching you on youtube taking apart the bike parts. don't stop. keep them coming. you're my fav mechanics and step uncle who lives far from my hometown. :)
Uhn,
How funny I feel the same way. I'm over here taking bikes apart and watching these
videos. I have never put one back together but soon.
I feel ya, hell I'm a 30 year old dude who's just getting into MTB seriously and tinkering around and wanting to learn how to take apart/fix/lube my bikes parts. Thank goodness for TH-cam!
Michael Fabian I'm with ya guys on that. Except if he were my uncle there would be a lot of cussing.
I almost cried.
I love watching these videos, they really help shape me into a better mechanic. They help me learn to stay calm while working.
Hello.
I want to thank you enormously your educational videos about the inner mechanisms of bike's parts. In my case, the have helped a lot particularly and generally.
Particularly, to fix a frozen read derailleur Tiagra 4600 b-axle. Thanks to this video, and another one of your dedicated to that particular problem, I was able to understand the working mechanism of this part, understand the root cause and fixing it.
Generally, because by watching your videos and replicating your actions, I grew in confidence in my manual abilities and I began to develop some creativity in how to solve some issues, the most basic one, for example, how to replicate some of your actions when I didn't have your tools with the ones I have. Thanks to that, yesterday, with a problem of a frozen arm bolt unit, I had the confidence to dismount the whole brake piece by piece, lube everything and make it again fully functional.
Thanks to you, besides saving a huge amount of money and making usable again parts that I would have discarded wasting many valuable materials from a limited supply in the Earth, I had a lot of fun and learnt a lot.
Thanks!
Very well done and is a testimony to your attention to detail. You're somehow able to manipulate the body of the derailleur without ever obscuring the mechanical element you're concentrating on at the time. This is a talent that is lacking in many an instructional video and makes your's especially easy to assimilate. Very good hand work with the respective tools as well. Another worthy entry in your series.
Saved my life! Took it apart without filming or photographing and could not get it back together. Thank you.
Life saver !! I dismantled the rear derailleur, thereafter reassembly with the spring to be kept under tension became an issue. Thanks for a Great Tutorial.
Thank you very much RJ for sharing your knowledge. I just destroyed a Tiagra derailleur... I had a spare 105 but needed a long cage for a 34 granny ring, so I swapped them out and now have a free upgrade! Subscribed!
This is really helpful. Will recommend to all my biking friends. YOU ARE THE MAN!!!
Thank you so much for this one RJ. I had to take mine apart because the pivot bolt was seized and so wasn't pivoting! I couldn't work out how to get that part back together again!! You saved the day, and my sanity, seriously!! 👌👌👌
Years go by, new RDs are getting released, yet this video still works. Mine wasn't loose, was completely stuck. Found a random seal stuck inside of the spring rather than sitting on the outside.
Thanks.
This may be the best how-to video I've seen on youtube. Thank you! I appreciate how you pointed out all the little details of what to keep track of. And the camera angle was perfect so I could see all the little details. I would have likely ended up with a pile of pieces and hopelessness without this video. Now I've got my derailleur back together with new pulleys.
I just watch it for a refresher.Thank you for your videos
Thanks for a really useful video - have just removed, regreased and reinstalled a stiff pivot bolt on a year 2000 XT SGS derailleur thanks to you!
Didn't have a vice (limey spelling!) to hand but with a 5mm allen key in the pivot bolt and a 3mm one hooked through the B-tension screw hole, it was very easy to rotate the assembly against the spring to locate it correctly; hope that might help someone out there.
RJ thank you. Your video was exactly what I needed. Your directions were awesome and advice solid. I was able to service my old 105 and get it put back together correctly. Thanks again.
You saved me. Thank you! I'm reasonable good at fixing my bike, but never had a rear derailleur spring pop out on me! I thought I killed my Arabesque 600, because I didn't know how to twist the coil to get sufficient tension. You really helped me out :)
So grateful for this. Took just a couple of mins with brake cleaner, mucoff degreaser and some thick grease. Probably would have taken way longer without this video!
A really time consuming task explained and demonstrated very well.Thanks!
Outstanding video. Very informative and detailed. Nicely done. It was very helpful for me on my 2011 Scott Sportster rescue project
Thanks for the video, it helped me to assemble my derailleur! Using pliers and wise was the key!
Saved me buying a new unit. Thanks 🙏
Thanks for a super instructional video. I have 5 short vintage shimano XT short cage deraillers I need to convert to long cage. I understand now!!
You are amazing, just what i was looking for. Amazing detail. Hopefully I can fix mines now.
Thanks for the videos I have learned so much regards from Mexico
the video is very helpful! Thank you very much for sharing your knowledge!
Excellent video! Thanks so much for sharing that!
Helped a ton! Thank you a lot bro!
I thought the spring of my derailleur was broken. But it was only sprung out of the guidance. With your video it was easy to fix. Thank you! you saved me 40$ for a new derailleur.
Thank you, now I know how to clean the derailleur very helpful
threaded my chain wrong thru the rear deraileur and didn't want to break my chain again, this was very helpful for me, thank you!
Thanks so much!! I wanted to transfer cages between 2 mechs and this was the perfect instruction!!! Clear, to the point, informative! THANK YOU!
Very useful video!! I got hung up on the hanger bolt and that spring-loaded situation!
Once again got my answer from RJ vid. I didnt take note which pulley was guide/tension. So the one with metal axel housing goes guide. Thx!
I would like more videos on different derailures. Very entertaining 😺
The pivot bolt at 13 minutes saved me. Though I had no vice. So I had to get a little tricky. 2/10 wouldnt do again. But leveraging the allen against me worked the same. That bastard. I had to fix it because it lost its C clip. Without this video I probably wouldn’t be riding again fora few weeks. Thank you as always RJ.
super. it helped me reassemble the derailleur. thanks
Fantastic video. Well done!
Awsome, you just saved my day, thanks!!!
really interesting and great explanation
keep up great vids
eternal thanks
Just did this on a Deore M591 SGS. Everything the same as RJ's 105, except, B-spring tension was a lot higher. Even using the same method, getting the B-spring assembly back together was quite difficult. The bike has been ridden 5 seasons on a lot of gritty trails. The outside of the derailer was dirty. The pulleys needed cleaning. (pulleys have been cleaned annually) But, inside the P and B spring chambers was clean! I really did not have to go through that pain at all! Cleaning the pulleys and exterior was all that was really needed. Next time, I'm leaving that B-spring alone!
+Mark Holm Yeah, a long cage would need more tension due to leverage differences.
The P-spring on the Deore, unlike the B-spring, was a piece of cake to reassemble.

You legend!! thanks for the vid, now I can put my derailleur back together lol
life savior - very helpful video thank you
RJ has such a nice voice. I would listen to him do a radio show or podcast about bikes.
I can't stand my voice. LOL
Master Skill!
nice tutorial sir,,,a'm very interestingto learn
I've attempted to disassemble and clean mine(a shimano200)but chicken out halfway......now I'm brave as nuts. Thank you very much.
Mahalo, RJ!
Fentastic sir👍🏼
great video
The Best video ;) thanks
I just finished rebuilding a Schwinn (Shimano) GT400 from a 73 Le Tour. It is amazing how much is the same between these derailleurs.
Thank you very much
brilliant!
Thanks a lot
The tension pulley is directional, so make sure you look at the direction arrow on that pulley.
Thanks for making superb bike repair videos! I'm currently doing a restoration project with my old bike (A 12 year old "Crescent", swedish traditional bike brand) and every time I don't know how to fix something - your videos helps me out every time. Keep up the good work!
Cool! Thanks!
RJ The Bike Guy Do you know the kind of derailleurs that swing around with a cage and a hangar hook like thing that is labeled index system at the bottom?
Huh? You lost me.
They're labeled index system. Look at Huffy Superia bikes and you'll see one called Power Index System. That's the kind of derailleur I'm talking about.
Jonathan Chuck Huffy are cheap bikes with cheap components.It's just a really cheap derailleur.
Because the pulley wheels are of slightly different width (size) I found that the length of the holding screws differ also (ever so slightly) - so best to keep track of which screw/axle belongs to which wheel, to save messing around :)
thanx for sharing, cool vid.
That does not make sense. The width of the plastic pulleys is different so that the G pulley can slide on its metal bushing a bit to adjust to the position of the sprocket. The length of the metal bushings is the same, and the screws are the same, the difference if there is any is unimportant since the bushings are the same size.
Thank you!
very good
I am currently doing a Road/commuter bike build for a friend and this helped me alot. Since i am trying to do a good job.
But i dont think il be touching the pivot bolt. :D
thank you so much! Btw you don't necessarily need a vice to do that. A 2nd person or a screw clamp to hold the allen key is fine.
thank you for your helpful video.do you know how to remove the cage from the derailleur in an Ultegra derailleur? (i.e. the equivalent from the 2:55 mark?) many thanks
Hi RJ, nice video, nicely in detail explained. At the begining you named the guide pulley as the lower one, or at least it is what it seems. And at the end you named the upper one the guide pulley. I'm confused now although I've always thought that the guide is the upper one and the tension is the lower one because it mantains the chain tension while the G guides the chain onto the sprockets. Thanks RJ
thanks my friend!!!!!!!
with a pointy metal tool, you can remove the parallelogram spring (and get it back on), makes it a lot easier to clean the inside of the paralellogram.
You are very observant taking things apart, maybe You could do the same with Shimano optical light action advanced shifter for rear dereileur thks
Am Filipino new sub
Hi, thank you very much for the video! On Shimano Altus current rear derailleur there is a kind of hatch or trap door instead of the 2mm screw you mention at 3'. Would you know how it works? Thanks again!
As usual - nowhere to find? nah! RJ has everything, I owe you half of a liter of Polish Vodka!
Thx sir
Thank you so much
I have a question I have a Rd6500 rear derailleur 9speed.
Can I disassemble rd 6500 the same way?
20:25 do you recommend using medium threadlocker to keep things in place without the added friction of overtightening the bolts?
imagine getting your bike serviced by this guy
Jeez, how many different lubes u got?
I'm impressed, great vid RJ
vicsimmonds I try to use the best lube for the particular applications.
One for each hole ;)
Hey, sorry for the late question. For the spring in the derailleur, what happens if you insert the spring into the second plate hole, and not the first?
My shifting for my ultegra 6700 isnt very good and I was wondering if I could engage the spring in the second plate to have it under more tension.... alternatively, I would replace the spring.
Merci for the ''how to reload the pivot spring '' at 15:10. My cheap Altus explode all around just when I simply unscrew-it from the frame hanger ... very poor circlip shimano !
Please make video how to diasasembly n assemblied RD shimano alivio m4000 or M3100, thanks b4
hello! have u experienced getting the thread hole of the b screw loose? if yes how did u repair it? thanks
I have a Shimano Alivio 4000 derailleur, can it be disassembled like the video derailleur?
Thanks
Can you please do a video about replacing a bent rear derailleur cage? Particularly swapping out a short cage for a long cage?
Just buy a new (used) derailleur. Easier.
are all rear derailleurs the same as i should maybe replace the one on mountain bike ??
Just how do you get your bike chains and derailleurs so clean?
This newer 105 RD looks very similar to the 1050 model from the 90's
Hey RJ. I seem to keep stumbling upon your videos and always find them helpful. So I finally got around to subscribing.
Did you ever work on any of Microshift’s derailleurs? I’m playing around with a 9-speed Advent RD on a 20” bike and would like to shorten the cage to clear the ground a little better while hopefully maintaining the shifting ability.
Wondering if Shimano cages would fit the Microshift derailleur.
Not yet!
What lube to you use for ceramic bushings?
One of the easiest things to take apart. One of the hardest to put back together. The last spring is the most difficult and need a vice.
OK let's say I want to take a riveted derailleur apart, how would I put it back together? Are there screws I can use to put the derailleur back together?
The section about b-axle reassembly (starting 12:55) should only be followed if you've got a RD-5600. While reassembling a RD-6600 (same period, roughly), I made the mistake of blindly following this video's advice about which spring tension hole to use and will need to buy new parts for the assembly. RJ generally gives good advice but it needs more disclaimers when giving specific advice when there are many different versions of derailleur with varying construction.
Also, I'd recommend against using vice grips on the tab as RJ does - I almost screwed up the threads for the b-limit screws.
Pro tip, if it seems like you need to rotate the spring more than 90 degrees, you're probably using the wrong hole.
Great video RJ. Question, can the cage plates be replaced with longer plates to allow for a larger rear cog, I.e. more capacity for lower gearing? Or do I need larger capacity derailleur? Thanks
They used to do stuff like that. The parts would need to be compatible, etc. Easier just to buy a longer cage derailleur.

Question: why do you use oil on the pulleys and not marine grease?Love your videos... thanks
+Bicyle Man Grease makes them more sluggish. I use a synthetic oil. You want to make sure whatever you use is safe for the plastic.
what size are those high low adj screws ? (size and pitch?) And B screw too - I piked up a bike with Acera and some gorilla mangled the screws, thanks so much love your videos!
I do not know. There is probably not a standard size.
thanks, I imagine installing it on frame and lining up the smallest 3 cogs (2 pulley) and smallest ring RD should give me straight cage line?
+attila elekes Not sure. Make sure your derailleur hanger is straight first!
I have been using my road bike with a Shimano 105 rear derailleur for about 4 years already but I've no idea how to service the rear derailleur. It's embarrassing that I haven't disassembled it to clean and lube. It's a good thing that I'm not having any problem with it but I have to clean it. How often do we need to service a rear derailleur? Thank you so much, RJ The Bike Guy. This video is really helpful and informative.
+Michael Angelo Samson I usually just clean them with soap and water. And drip a little synthetic oil into the pivot points. I rarely disassemble them to the point in this video. I will however remove the pulleys to clean and lube those. I service as needed. Though it never hurts to clean and lube them once in a while.
That's the only thing I do with my rear derailleur regularly, clean and lube the pulleys. Thanks, RJ.
That's usually enough.
For some reason my old Shimano Deore RD-M591 derailleur has its pivot bolt really stuck in there. What should I try?
please help me ; i have a saiguan index rear derailleur and i can not take off its cage to put it on another derailleur ; i mean there is no bolt to unscrew
Hey! Vincent's girlfriend again. I'm only 1/2 way through but thank you! Things are making more sense. I'm dealing with a really nasty rear derailleur on a 2000 Trek 4500. I rescued it from a neglectful and abusive owner. ($35 fee) lol
One question!
Do you have minions? That's what I call the things I can't see that come and take small parts like screws and washers and especially springs! They really love stealing those.
It will be sitting right next to me carefully placed, I look away, work for a bit and sometimes when I go to get the screw,for example, it's gone! And it never comes back! (Vincent says I'm delusional. 🙄)
My point? If you don't have any minions, I'll be glad to send you mine!
Okay back to my restoration project! I'll be back! Be afraid, be very afraid. 🤭
LOL! Not generally. Will often have a box and put the parts in the box as I remove them, so they don't get lost.
@@RJTheBikeGuy A box. That's a good idea. But they'll just steall the whole box! Lol
I am careful. Well, careful-ish.
Okay in all honesty I just kind of set things beside me on the floor and I have a bad habit of jumping up to get a tool or something and...🤷
Note to self: Find a box.
How do you remember exactly where each piece goes without writing it down? Its almost impossible... Great video by the way.
Thanks
Lay the pieces out in order. Maybe take photos. make notes.
Thanks so much for this video. I was doing it for the first time with my 105 RD 5800 and it worked, everything's fine. I just have one question - how did you clean the non-separable part of the derailleur? Just with brush or you have used some solvent/benzine?
Probably soap, warm water and a scrub brush.
@@RJTheBikeGuy Thank you!
