How To Adjust Shimano Nexus 3 Speed Hub Shifter Cable
HTML-код
- Опубликовано: 5 ноя 2020
- I show how to adjust the shift cable on a Shimano Nexus Inter 3 three speed internal geared hub. It's a fast and easy adjustment. And you pretty much just need a 10mm wrench.

Hey rj my quillstem expander doesnt fit with my 1 1/8 steerer tube.what should i do?
@@simplecyclist9214 Get one to fit your steerer.
How about i sand the expander. Is it ok?
By the way my steerer is too old like 90s
Please i need 1 ancient bike please 😞😢
I miss your weekly videos. you have a great way of explaining everything down to the little details. there's always GCN however all the bikes and tech are all new and expensive. there was the bikemanforu silly but one could still learn repair from him. if you stop where will I go for such great content videos ???? lots out there on the web however most not worth watching unless I can't fall asleep. I also watch park tool however they are trying too hard to be funny and miss out on the small details. hope to see many more of your repair videos soon . keep up the great work
Haven't posted in a while. Hope everything is fine and you're just lazy or fed up of it all, lol. Best wishes for 2021 to you and family. Cheers.
Great video! World needs helpers like you. I bought a second hand bike and the gears were messed up. Got them fixed thanks to you!
This works for the later plastic-housing Nexus 3-speed clickboxes as well. Also, it is always a good idea to cycle the shifter about 5-8 times during adjustment - a few times more than you'd expect. Occasionally you'll find the adjustment won't hold it's initial position. If anything sticks, undo the clickbox using the 10mm wrench at the back (cable will stay on) and check the hub pushrod for grease or a kink in the spring.
Hi I have one of these 2nd doesn’t work so the method you state should fix this?
Bought a Priority and had it "professionally" assembled and inspected. Besides assembly delays, the front wheel wasn't even aligned with the handlebars. I'm new to bicycling, and that's probably a pretty minor thing since I imagine most people would adjust the saddle and bars anyway, but it made me question what else they missed.
Of course, the bell crank needed a lot of adjustment. Thanks for the quick and concise video, much unlike this comment. 🙂
That was a perfect explanation! I'm back on the road. Thank you.
I bought an urban bike with nexus 3 last year and I'm so happy with it! I usually do this adjustment every 10 or so rides (I usually commute with it so my rides are always the same).
Although I know how to adjust it, I watched this because RJ's videos are satisfying.
Plus, repetition is the mother of knowledge!
same, and honestly I've thought this is something a normal person can figure out by just looking at it.. but I guess common sense is slowly going extinct
Sweet! I needed this!
Just what I needed to know for my Nexus after changing the tyre. Thank you very much!
That was a huge help. THANK YOU.
Thanks RJ! Great help!!!
Friend from Santiago del Estero Argentina I greet you and congratulate you for your tremendous contribution to those of us who like this sport and understand little about mechanics. I see you more and I admire you more. Hugs and good luck.
Thx! My 3-speed is shifting now!
I seldom work on three-speeds but this was an interesting video to watch, so thanks RJ.
Very informative and addictive videos. I just continue to love watching all your videos. Very clear and correct techniques .. waiting for the next one.. It helped me install rear and front disc brakes from your previous videos. hope you come up with more..
Great video! Thanks!
That is excellent video. So, adjust the tension's cable is a thing that a good biker must be aware of. Thanks, RJ. ( Pascal, from FRANCE ).
Very helpful many thanks.
Great vid, so informative! Thanks our lad. Much appreciated 🤙
Ty I just got a nice bike to fix it has the nexus 3 hub newer model it rides great like a dream just had some noise when I go out of first I noticed gonna try to adjust tomorrw thanks 😊
Thankyou, just saved me taking my bike to a shop
As always, you give a concise and understandable explanation of how to do something. Much appreciated, RJ, keep the tutorials coming!
Suggestion: a video on how to disassemble the nexus 3 and dip it into shimano oil for maintenance. And reassemble. I suspect some people would be interested, that would get clicked quite a lot, i don’t see clear tutorials out there. I thought about doing it for my mother’s bike but was put off by the lack of info, i didn’t want to end up with a bunch of small parts on the table and being unable to reassemble. Just suggesting.
Anyway, video liked as usual.
Always wanted to grease one of these up with 00 grease to see if it's equally effective. Sturmey uses that stuff in their modern hubs.
nice ! timely add to the Sturmey Repair vids. this is my Winter project
Super! Thanks for the nice explanation!
This is right on time ! I went to some shops to buy parts for my bike and true my rear wheel and I saw a bicycle with a 3 speed shifter , I am so curious but have no idea how to find one or what to search for
Search for 3 speed bikes.
Thank you very much for your bike Technology talk
Back in June I picked up a Marin beach cruiser bike with Nexus three speed for low cost. After changing to a more normal seat and handlebars, I'm planning to use it as my winter bike this year. With all the gears and even the brake inside the rear hub, it should survive winter better than most bikes with caliper brakes and external gears.
totally. a low-ride bike with fatter tires keeps you upright on the ice & snow
many many thanks.
Thank you.
The one I have uses the stamped steel bell crank with a plastic cover that has to come off for adjustment. In your video you can see a black line on the push rod through the window. When that line is even with the end of the axle in second gear you have it right.
Thank u
Hvala
Thanks for all the content. I have been binging a lot on your channel. Favorite so far was the 22 thrift store adventure. Question. Can you tell me where you get most of your parts from? Keep on teaching!

Why don't you do anymore of those bigger overhaul videos? Somehow they don't ever get repetitive and always fun to watch
Great mr jr, keep that great job, i kkeep learnig, thanks for sharing, old suscriber, joe, say hello from panama, joe. Thanks
I have been to Panama once, and also through the Canal. Hoping to go through the Canal again next year. Beautiful country!
Hi friend,
If I removed the bell crank assy. ( the module that contains the yellow indicator mark) and re-installed it but didn't quite fully seat it towards the bike's dropout, will the yellow mark be off?
thumbs up!
Hi do you know whether nexus 3 speed and 4 speed are the same spoke length, I have a working 3 speed hub on a wheel and a non working 4 speed hub on another wheel and wanted to swap them over, thanks
Hey rj I really need your help. I have these old bike with 4 speed on the crank and 8 speed on the rear. Where can I find derailleur that will be compatible with this set-up. I can send you the images of the crank and the rear. Thanks a lot
Hi Mate,
Super nice content as always.
Can you please make some content on cross chaining problem with front and rear derailleur in bikes.
Desperately waiting for this.
Don't cross chain.
Nice video dude! Thank you very much for this, it’s very useful. Can you make also a video on how to adjust/service the rear hub and the gears on a batavus internal gear rear hub?
Is it actually made by Batavus? Or it just on a Batavus bike?
@@RJTheBikeGuy to be honest, i don’t know who makes the hub but i’ve seen the same rear hub on almost every Batavus bike and i’m pretty sure it’s not made by Shimano. The braking system is very smart (you have the brake on the hand but the brake is inside the hub and the gears also)
@@RJTheBikeGuy found it!! This is the one ruclips.net/video/jTOYKHD5nI8/видео.html
@@mitzij Okay, I have never seen one of those. So I can't really do a video of one if I don't have one. LOL
@@RJTheBikeGuy while working in Netherlands, couple of years ago, i’ve used a few Batavus bikes and i have to tell you they are something else. I’m not in Netherlands anymore but i’m planning to buy a bike like that (second hand - and i’m pretty sure it needa some adjustments and tlc) and i have doubts because i don’t know how to adjust anything on the rear wheel (gears, brakes, etc). Thank you very much for your support RJ, you’re doing a great job! And by the way, i found some great tips on your channel everytime i didn’t knew how to fix something on a bike (and i used to work in a bike factory in Netherlands) cheers!
When will you post a video?
My adjustment could be an internal issue? Maybe the cables too tight? I need to move the yellow indicator further out but I already have the adjustment screw screwed all the way in and I confirmed that the adjuster mechanism is pushed all the way onto the hub nut. So what's my next move?
Damn, this really worked.
My problem was that in 1st and 2nd gear the bike worked well but in 3rd gear it would keep sliding kinda like if the chain got loose. Turns out it was jumping back and forth between 2nd and 3rd gear.
which speed position needs that yellow marker to be centered? 1 2 3 or which?
Any idea what would cause it to slip while pedaling and feel like going from 1st to 3rd for a few seconds and then kicking back in?
My bike doesn't change gears at all but I will try this
Why some said have to adjust from down side first then tighten or loosen cable
Hi, the yellow indicator dot is stuck at 1 position for Gears 1 & 2. just off to the right of the 2 yellow lines. i loosened the lock nut & tried turning, but it can only move inwards, towards "Gear 3". Gear 3 is fine, it can be engaged. any help? thanks.
Hi R. J just checking in see if you're good bud 🙋👍
I am doing okay.
I trust the Shimano Nexus 3 IGH is, by an order of magnitude, more reliable than the Nexus 7/ 8 IGH Hubs? I can't even even imagjne the Alfine 11s and NuViolo CVTs. If you were building a bike for world wide adventure touring, would you personally trust a ROHLOFF 14 IGH and a PINION 12/18 with a GATES Carbon Belt Drive for foul weather reliabilty? Still prefer traditional cassette geared drivetrain for bulletproof reliability and ease of service? New subscriber here. You disassembly and reassembly of that NEXUS 8 was flippin mind blowing. Def designed by Aliens. That the human mind can conceive, design, and fabricate such a complex device is astounding. Great job!
Hello RJ and thanks for the valuable knowledge.i have a sparta bike with the 3 gear nexus system.1 and 2 gear works like a charm,but when i put the 3rd gear the system blocks,the axxon blocks with the wheel and the axxon screw(where the shimano silver thing is screwed on) goes loose because the silver thing and the gears wire act like an opposite force.i tried lubricating and loosing up the cones a bit,everything seems to work ok and nice until i put the 3rd gear...any help would be highly apreciated!
Sorry, I can't diagnose the problem without working on the bike.
Hi RJ, i have a pair of shimano sl m315 7 speed shifters than i took out my bike and i´m putting on other bike but the right shifter screen doesn´t show the actual gear, there is any way of making it work again? thanks cheers from colombia
Maybe yes, or maybe no.
My nexus inter-m doesn't have that dial and when I shift to a high gear and try to ahift to low gear again, it takes time to make it shift, the cable housing is also loose on the shifter side, it moves while I shift.
Nice video! I love these kind of hubs. I have a random question for you rj (or anyone in the comments): do 12,5 inch pneumatic scooter tires (the xiaomi type) fit on a 12,5 inch bike rim? They're way more durable than normal kid's bike tires. It's for my recumbent bike, so I need something that also can handle my weight.
No idea.
Do you have an old 70s volkcycle you could do a totorial on
I do not.
when are you going to to do repair on new bikes i need your knowledge to fix my bikes
knowledge (your knowledge is very helpful)
I am guessing this bike is from 2010-13. I have other videos on newer bikes. If you are looking for videos repairing brand new bikes, forget it. They generally don't need to be repaired.
Hey Rj I have a cassette that has healthy teeth but has movement side to side I tightened it up and it didn’t work. I checked the freehub and it doesn’t seems to be damaged. But when the cassette is inserted it looks like the cassette doesn’t fit perfectly
I can't diagnose your bike without working on it.
Hi, i want ask whether my current 10 speed freehub can fit a 12 speed cassette, i already done my research about that , but i could not find any proof that it will fit.
Probably not.
Is there anyway you could overhaul a srsuntor air fork they are great forks but they get sticky after time
I am sure there is. I haven't. I don't have any lying around.
Hey rj i just got new chain which is 11 speed and a old 11speed cassette i think almost a year and its still in a good condition. The problem is whenever i use 1-4 cogs its jumping and making a loud noice when i use 6-11 its good tho. Please help me how to solve this problem.

Hi RJ my name is Martin and I have a bike I am working on and I can not get the nut for the rear wheel axle to undo so that I can remove the freewheel. No matter how tight I make a locking nut on the opposite side they undo instead of the nut I need off. Is there a tool that will fit past the nut and hold the lower part past the spacer or is there a way to hold the spacer so that the nut can be removed? If you are not sure of what I am trying to describe I can take a photo with what I am trying to describe pointed out for you if want.
Regards Martin.
How to change brake cable on condorino handlebar
You change brake cables on brakes. Not handlebars.
Hey rj do you do personal bike work? As in if I were to take my bike to you would you fix it for the right price?
I do not.
Hi RjtheBikeGuy kinda random question but how will i know if my freewheel needs to be replaced? Keep up the good work!
Because the chain will jump and skip under load because the teeth on the cogs are worn.
What he said.
Hey, RJ! I have a project and im planning to use a nexus3, but I cant use the standard shifter with my bars... Do you know about any shifter with the same amount of pull? I dont wanna waste the gears with the wrong shifter.
Not sure. You will have to do research.
@@RJTheBikeGuy Thanks anyway!
Indicator should fall between lines in 2nd gear.
Loosen locknut.
Counter clockwise: in toward the hub
Clockwise: away from the hub
Tighten locknut.
Anybody know what happen to RJ ? Miss all the great video's..
I heard he moved to Tibet and became a monk.
@@RJTheBikeGuy lol!!! Glad your ok.
Hey RJ..... I have a 2001 Royce Union ST 150 blue and white 26-in wheels the frame is a 17-inch..... Just wanted to see if you know anything about these bikes it shows on the front that is made in China
I know nothing about it other than what you posted.
Wished I could send you a picture of the bike
i use to own a vintage dunelt and thats why my 3 spd shifter worked sketchy sometimes .
Um...I don't get why your shifter would have problems because of a bike you used to own....
Hey RJ I'm holding 18 loose bearings in my hand, (building a time trial bike)
"Have you ever thought of chopping up and drilling out an old bike?"

How do you remove it?
How to fix wobble freewheel
Hello ,so a unrelated topic . I was going to change my bottom bracket with cage bearings to a sealed bearing cartridge .
Until I found out the spindle is 145mm . I only see up to 127.5
I have about 10mm inside room for the smallest chain ring . X 2 sides that's 20 mm
From 145 mm . Do you think a 127.5 would be long enough ?
Measure the spindle. Not the threaded part.

Can u put a 8 speed freewheel cassette on a 7 speed freewheel ream
Anything above 7 speed freewheels are junk. And the axle would need to be longer. Get a cassette wheel.
@@RJTheBikeGuy ok thanks that good to no. I have a mtn bike with a flex frame that older and I really like it but the arms that hold the back wheel is bent a little. Can I take arms from a nother bike. Is there bearings in the flex joint or just a bushing
@@shevyman6430 Uh, you would probably need to take off the exact same model of bike. They are not universal.
Any cheap brake cables for MTB Shimano brake shift levers you can recommend, please? I read reviews complaining about the barrel head size, either too big or too small. I don't know which one to get. Thanks. Happy Thanksgiving!
Go to your local bike shops. I buy them in boxes of 100, as many of the shops do.
@@RJTheBikeGuy thanks RJ. But the bike shops here are not in the retail business for cables. They sell them for 8-10 bucks apiece, for which I can get 10 sets on Amazon.
So when I pedel it pedels but my back wheel doesn’t move and I have a se big ripper

*Hi sir RJ! i have a question. Can i use triple crankset in my vintage bike? because my shifter is 3x7. i hope you notice my comment*
ps. your vids are so great!
Probably.
@@RJTheBikeGuy Thank you so much sir!
Nice video. Now my mom has no excuse not knowing how to adjust the gears on her bike.
I had a rsx sti, i want to upgrade to 8s is rsx is 8s? Because when im in a smallest cog ang keep shifting it it stills clicking. Anybody can help?
Can't tell you without working on your bike.
Why don’t you post anymore?
I have been. This video wasn't too long ago.
Sir i accidentally using outer brake cable for outer shifter cable, is it ok?
I know that inner shifter cable is thinner than brake cable
Shifting won't be as accurate.
@@RJTheBikeGuy thx sir
Aaaaaaaaaaaaaand : be sure to pour in some quality car oil into it too ! SA E 30 is fine . To get access, remove bell crank assembly and push rod then dribble oil into hollow axle end-----ten to thirty drops is good. Bring back oiling ports!!!!!
❤❤❤❤❤😊😊
I had one of these . The gear box kept popping out every time I shifted out .had to hold it down with zip ties
The bell crank? It clamps on with the bolt on the back side.
Why won't 3 gear shift my wheel locks up
Gear slips to higher wat is the solution
Adjust it like in this video. If still an issue, take it to a shop. I can't diagnose your bike telepathically.
Mr RJ, another great video thx,
I have a Question,
I made a short video of myself testing my tallbike for the first time.
I'm thinking of posting a 'build video'
But I feel obligated to Show Respect where it's due ( in the form of a shout out, A thank you, with a link to your channel)
The video will be safe and clean for all ages,
Is this ok with you?
Is this normal? Idk,
Also I only build freakbikes so we don't really compete for the same audience.
If the answer is No!
I understand thx anyway........Rock On
You can post whatever you want as long as you don't copy my videos. I probably wont be building any tall bikes.
@@RJTheBikeGuy, You know!....Most tallbike builders just kinda slap them together,
Annnnñd You sir, build such clean and professional bikes,
it would be awesome to see a tallbike by RJ....huh huh huh.?
(I never thought I'd build one either lol)
Hi RJ, I really enjoy your videos. I have learned a lot. I no longer have an active Facebook account, so will ask my question here and hope you will see and answer it. I want to modify a 3 x 8 derailleur system into a 1 x 5. Can't find individual cogs anywhere, so my plan is to take a 10 speed cassette, disassemble the cogs, and mount them on an 8 cog cassette. I have an SHIMANO HG50 8 Speed Mountain Bike Cassette
with Cogs 11-13-15-18-21-24-28-34. I want to disassemble this cassette as well and restack and rivet the cogs thus: 11-13-(16)-(20)-(28)-(36)-(50)-34, using only the cogs in parenthesis. My question is "will the derailleur be capable of making a smooth shift from the 36T cog to the 50T cog". I have looked but have not found any information that says what the maximum number of link variance a derailleur can handle.
Another question I have is will a SRAM X.4 8-Speed Trigger Set work on the Shimano HG 50?
Thank you for any help you care to send my way. Have a good one!

hello rj, i'm fernando from argentina, i would really appreciate if you could translate your videos into spanish, maybe it is possible for you to do it, i'm telling you as an idea, thank you very much, i love your videos
I don't speak Spanish.
Turn on subtitles bro
Finally a derailer I can figure out how to adjust.
Barrels or screws bro,just look up you're derailleur and figure out which one moves which way.
i have never seen a Sturmey Nexus adjuster box. looks better protected than the ball-chain adjuster
My son, 6'5", raised the seat of an Electra, too small for him. Sitting on the seat, he toted his toddlers everywhere, but the seat pole bent the frame backward. How would that be possible to fix if salvageable? Dispose of bike?
He has a new bike for his size now. The previous bike was a $300 bike. Grease the seat bar and slowly attempt to reinsert it into the frame. The frame in front of the seat, joins to meet the frame of the seat right at the bend.
So 90% of the seat bar was pulled out of the frame, and tightened for his leg length, meaning as he rode the bike with the elevated seat, it bent the frame so the seat bent back toward the back wheel, putting a significant bend in the frame.
One guess was to brace the frame with a clamp for pipe that slowly tightens the frame back enough to get the seat post back into the frame. Who would I donate it to.
If the frame is bent, it is probably junk now. Get a new frame, and swap the parts maybe.
No vids. Hope The bike guy is ok
I just posted a video a few days ago.
Why did you stop posting
I just posted a video.
Are you planning to do a teardown and overhaul of one of these hubs some day? Learn so much from your videos.
No I’m not
Maybe one of these days. I have done 3 speed Sturmey Archer hubs.
@@RJTheBikeGuy I opened and refurbished my Nexus 3 speed the other day and it's actually very similar to the S/A 3 speed hub.
