Installing / Adjusting your Rear Derailleur

[waiotlonewolf]

Perfect video. I'm dealing with an old '79 Peugeot and couldn't figure out the Simplex derailer, but this video helped out a lot. Thanks for this. Sweet 'stache by the way.

what if its a rapid rise?

[joeman3429]

I've been wondering youtube and the internet all day and yours is the most detailed and informative video I've found on derailleur adjustment. Plus you seem like a nice person.

[gsteptoe]

ah yeah. get bumping and grinding on the cassette

[Grantham777]

Great Video! Thanks.

[Cyclocyclops]

Just saved my race tomorrow! Thanks!

[rickfuzzy]

Great video, best on rear derailleur adjustment i have seen so far

[ender52]

Awesome video. Thanks so much for helping me get my new derailleur shifting perfectly.

[puredead77]

i kinda figured what the b-screw was for but i over screwed it thinking that was ok and it messed my gearing up without me realising.

Cheers mateyou have saved me some pounds and a trip to my LBS

Also i have noticed he uses the right lever to brake the back wheel, is that down to personal preferance?

[TheRealEmskiHelp]

@puredead77 Here in the UK, our right lever has always the back.

this video was very helpful

[Ninja238]

still don't quite get it. do the limiter scews actually effect the allignment of the chain or just how far the derailer can travel?

[wsmac7]

@Ninja238 Limiter screws only affect the lateral (side to side) movement of the derailleur. H or High (usually the upper screw) adjusts how far the derailleur moves the chain when it's closest to the largest gear on your rear cassette. L or Low (usually the bottom screw) adjusts how far the derailleur moves the chain when it's closest to the smallest gear. So, yes it affects the travel of the derailleur, which also affects the alignment of the chain from the derailleur to the gears.

[wsmac7]

@Ninja238 To add... the overall alignment of the chain comes from differing factors... derailleur, wheel dish, bottom bracket/crank adjustment, rear stay alignment, etc. I'm not sure if you are talking about this type of alignment. or just the derailleur adjustment.

[wsmac7]

@wsmac7 Oops... I shouldn't have said wheel dish... cog spacing is more like it :)

[Dannyisgreatful]

thanks! :)

[CineGolem]

Great tutorial but where should the high and low limit screws begin? Should they tightened all the way in or out...?

[wsmac7]

@CineGolem Neither all the way in or out. With the chain moved to either extreme (High or Low gear), moving the screw in small increments should move the derailleur arm left or right. You should be able to see the movement easily. When the adjustment is close to being 'wrong', you should start hearing mechanical 'chatter'. Look at the derailleur & cassette from behind the bike, you can see the relationship between the two and line up the 'top' gear of the derailleur with the gear above it.

[here2there4life]

can someone please tell me how to make the arm thing of the derailleur go higher on the lowest cog so that the upper cog doesnt touch the lowest gear. On my bike they are touching so it gets stuck when i back pedal

[wsmac7]

@here2there4life I'm assuming you are talking about the gap between the teeth of the upper "cog" and the teeth of the gears on the rear cassette? I'm trying to use terminology here you will understand, going by your choice of names for the parts you mention. If it's this gap you are referring to, then it's the B-screw you need to be adjusting... it's the adjustment screw that sits by itself on the derailleur. You open or close the gap depending on the direction you turn it... try it and see.

[here2there4life]

@wsmac7 yeah im new to this stuff, but everytime i screw it all the way in, nothing moves, it doesn't do anything, even when i unscrew it all the way out, it doesnt do anything

[wsmac7]

@here2there4life You can still shift gears though? It's sounding like you need to check your cable tension. The derailleur should pivot freely where the B-screw adjusts. Check that also.  When you back the screw all the way out, you should be able to rotate the derailleur body by hand and see the tiny set-screw move away, then back to the little ledge on the derailleur body/hanger. Look at the screw and follow it through the body to see where it exits and you should see what I'm talking about.

[wsmac7]

@here2there4life Basically, meaning without other complications, there are four adjustments for the rear derailleur... 1- High limit 2- Low limit 3- Body angle or B-screw adjustment 4- Cable tension. Four simple steps... that seem to be more like 400 to some folks! I think this is one of the most problematic adjustments people have when trying to work on their own bikes. Good Luck, keep trying, and find a good mechanic... just in case ;)

[125TVThird]

thanks man this is way better help then the expect-village crap

[hpotter1097]

Great tip on using the "cable itself" [rather than the handlebar shifters] to make/check shifting.

Also, best explanation on what the "b-tension" screw adjustment does.

Many thanks!

[wiganmadlad]

to hard this shit im gonna have to take it to a shop

[TheWildheart68]

I have a rear derailer that has been installed wrong on a bike. I need to know

how to install it correctly. None of the gears work at all. Thanks

[MrdacPrdeli]

youre the best!

[biotechcancer1]

thank yyou, good job

[mrwilliwizard]

very well described thanks

[ihatemuckdjs]

I don't know what it is about these derailleurs, I just don't get it! This lad made a good video but I would like to see the movement on the derailleur as he is turning the screws! B tension? I still don't even know what that is! Fuck sake, I wish I was blessed with a decent brain

[hymen0callis]

FIRST vid I found on here to mention the B tension screw. Not perfectly explained, but I guess I know now how to fix my shifting problems.

[vulpes02]

Best version of rear derailers I've seen. Provides background and theory, not just steps. Well done ;)

[freedomtakesaction]

This is a great tutorial. Thanks for the quick reference, it helped me fix my shift issues in less than 10 minutes.

[Pioter80]

sweet, best explanation I found so far

[Bhousm76]

UGH...my fuckin high limit screw isnt doing a GOD DAMN THING! the cage is rubbing on the chain like a mofo, and ive been working on this stupid fucking thing for an hour.

[jsblgb65]

Great video, doesn't have music playing while he's talking like so many dumbasses on Youtube.

[ihatemuckdjs]

@jsblgb65 Yea man, I am fucking sick of the poxy music

[CactassDupree]

My Ferrule is missing and the cable end is starting to fray. Do they make a ferrule that is slotted so I can just slip it on or do I have to replace the whole thing? Thanks VERY GOOD VID dupree

[bobamatic0]

@CactassDupree I work on bikes and no longer use ferrule ends. What I would do is I cut it back from the fray so I have a nice clean cable to work with.Then twist the end just a little bit (not a lot, just enough to get all the wires to stay together) then put a small amount of solder on the end with a soldering iron. If you don't use a lot of solder usually you can still easily slip it in and out of the little hole it goes through. Once you perfect that you'll never use ferrules again.

[Pioter80]

@bobamatic0 did you try some sort of "super glue" maybe?

[MaghoxFr]

@bobamatic0 thanks mate, I was just thinking about that but was kind of hesitant about actually doing it.

[bobamatic0]

@MaghoxFr Glad I could help.

[blokeinthekitchen]

Very helpful

Best video on youtube for adjusting a rear derailleur! Subscribed!

[pauloasis]

Thanks for posting this video . It has helped me out a lot . Cheers

[mferna08]

Marc, I'd like to know where you bought your jeans.

[lkiller123]

you really need to learn how to talk louder.

[pseudocube]

Thanks, man, you're a lifesaver!

[shoobedoorocketship]

wow, i got lost, i am going to have to watch this several times before i completely get it. thanks!

[RoPiris]

That was very clear and easy to understand. Very helpful and concise. Thanks!
