Shimano Nexus 3 Speed Adjustment | Internal-Gear Hub Bike Shifter Adjustment

I show you how you can adjust the Shimano Nexus 3 speed Internal-Gear Hub Bike Shifter easily. The problem on this bike was that it was jumping gears and going to the third gear although the shifter was set to second gear.
Steps for adjusting:
1) Set the shifter to the middle gear (second gear)
2) open the lug nut on the shifter with a 10mm key
3) turn the barrel roller (turn with pliers if tight)
4) adjust until you have the yellow dot between the white lines
5) close the lug nut again - DONE
If you have trouble getting the yellow line into position perhaps the shifter unit is out of place like in my case so I also show you how you can take the shifter unit off and position it correctly.

Thank you. Your video helped me understand a little more about the Nexus hub.

[@Homeneer]

Great to hear that.

[@mickyg51]

Thank you, you made it so easy to understand how to adjust the gearing. I have an issue with my new bike which should have been sorted out by the bicycle shop. After watching this video, I will do it myself. Keep those videos coming and take care.

[@Homeneer]

Thanks for the positive feedback 😊

[@ToPanPawel]

Thank you! I have same Nexus shifter and Im struggling to shift. I will try your method!

Did it work?

[@ryanhoyer]

Hello I am unable to keep the nexus system from popping off the frame. The hex screw spins and spins and will not bite down. Please help.

[@Homeneer]

Sorry to hear that. Sounds like the threads are worn on the hex screw. Dont have experience with fixing threads. I would just replace the whole shifter unit. Price should be 15 usd or even under.

[@920rookie]

Great video, presented like clockwork including intentional drops and recovery. I've just done a basic service of my Nexus 3sp, now I want to strip it back like you did. I'm not game to get into the planetary though. Probably just soak it in oil and put it back in?

[@scottdevore6218]

Thanks!!! 😁I was able to fix my jammed up 3 speed myself...which saved me time (taking it ti bike shop) and $$$. This is the best video because it is the only one I saw that mentioned removing the whole shifter, which is what mine needed. Mine got messed up when front handlebars got turned all the way around after transport - it pulled the whole cable too tight all the way to the end.

[@Homeneer]

Great to hear that. It's always so rewarding when one can solve something like this by one self.

[@paul6925]

Thanks bruv this is a confusing adjustment to make and you covered everything.
Shimano specs says it isn't waterproof! Explains why mine is now seized after riding it in -20c through salty slush for 5 years. Sometimes it would freeze solid too because it got moisture in it. Surprised it didn't die sooner

[@Homeneer]

Thanks for the positive feedback 😊

[@buffalomind6838]

Are you serious that it is not waterproof? That does it I can’t get that igh. I seen on another video that it is noisy as well, so this new information seals my decision on passing on purchasing a bike with it.

[@paul6925]

@@buffalomind6838 Yes if you go to their site you can dig around and find the specs. It worked fine in rain for me but once it flash froze it would seize up. I rode it a lot though and parked around outside. Still....

[@buffalomind6838]

@@paul6925 Thanks for the speedy response. I’m thinking it more thoroughly now that I am concerned with igh’s possibly not being waterproof, and the sound is also a big concern.
Another up question have you ever hit the shister box in the back?

Have you ever had the problem of the shifter popping off the wheel but while riding ? Keeps popping off

[@Homeneer]

Not really. Did you tighten the hex key and still popping off? If yes, I suspect the hex bolt or threads have gone bad. Could that be the case?

Super clear video. Thank you. In my case for some reason I can not even shift. Just bought bike with Shimano Nexus and shifter is stuck on gear 1 (shifter on the handle bar) and i can't turn the rubber wheel. I don't want to brake it so I don't turn with all the force but it doesn't seem to work. Can you help?

[@Homeneer]

Sorry not familiar with that issue

[@nubret]

thank you, it helped alot! now i can fix the shifting on my 16" folding bike :-)

[@Homeneer]

Great!

[@TheMrHoody]

Hi I have a little question for you: the bell crank (this grey thing you are showing in your video) of my Nexus 3 is cracked. If I buy a new one, do you think I can replace it without changing any other part of the shifter? I not good with repairing stuff but I think if i only have to replace that grey thing, it shouldn't be so difficult.

[@Homeneer]

Hi, sorry I'm not familiar repairing that part. The grey thing I call a spring in the video should be easy enough to change if you can find the part somewhere. So I would recommend trying it if the part isn't expensive. Still wondering is something stuck on the other side if that part in between cracked.

[@TheMrHoody]

@@Homeneer Hi, sorry that actually the whole thing that you call the shifter unit that was cracked. I brought my bike at the bike shop tho change my rear tyre and one week later the shifter just srpung out of my bike.That part is a little bit cracked so it can't be fixed on the bike again. I have to buy a new unit, what a shame.
Anyway thanks for the info!

[@Homeneer]

Oh okay. I think those are sold for around 15eur as a package including the shifter on the handlebar. Most likely you can just change the "shifter unit" and use the old wire and shifter. I would expect it to be a quite easy DIY fix.

is it possible to replace the twist grip shifter with bar end shifters? I just got a bike with this shifter but want to restyle the cockpit

Sorry I don't know. If they sell them for that model then yes. Otherwise wouldn't mess with it because shifters are often very precise about the cable pull amount.

Question, I have an old folding bike,a 3 speed sturmey archer that has a pin going in the hub. Would this Nexus one fit my bike? It is a universal uni sport fold up bike, maybe from early to mid 1980s

[@Homeneer]

Sorry I dont know. I recently fixed a 11 speed and discovered that the different brands have different distances between the sprockets. So my guess is mixing brands will not work. If the bike has a sturmey archer rear hub most likely it needs a shifter unit from the same brand.

[@Homeneer]

The principal for adjusting might be the same.

[@justmadeit2]

@@Homeneer Its a shimano hub,made in Japan, 3 speed with a part that screws on to the hub. Does this nexus one screw on?
