I have a charge plug 3 bike that I'm repurposing for touring. So I changed the cassette to a 11-36t and bought a m592 rear derailleur.

How ever I adjust it, it still has some kind of chain rubbing.

I took a short video of it (the clunking noise is just me spinning the cranks at uneven speed):

I also tried with another older version of 9 speed deore derailleur that works fine, so itīs not the dropout thatīs bent. I need one for my GFīs bike as well.

So it seems to my reading that you should use the older der

But to the problem- Hard to say but it sounds like the chain isn't completely under the cog and the soft noise is it catching on the portion of the cog dedicated to shifting (shift gate). If so then better adjustment/alignment is needed. Try to do this with no cable attached. As you're in the small cog a too tight cable could be pulling the der a slight amount. Andy.

I need one derailleur for my girlfriends bike as well. And I have really tried all of that.


Could the chain length be wrong? (itīs on the 50t front chainring in the video)

dsbrantjr

Is the chain threaded properly through the derailleur? It is an easy mistake to make. Can't see much in the video.

Wressen

I think so:

That is a 10 speed derailleur - is this a 10 speed setup with MTB shifters?
You refer to a 9 speed derailleur working fine - 10 speed MTB derailleurs and 9 speed derailleurs do not work together and are not compatible.

Wressen

Are you sure? The guy i bought it from said it was this one: Shimano Deore M592 Shadow 9 Speed Rear Mech | Chain Reaction Cycles

gsa103

The M592 is a 9-speed mountain derailleur. It is compatible with 9-speed MTN shifters and 9/10-speed ROAD shifters. It is NOT compatible with 10-speed MTN shifters. Given the OP has road style bars, I suspect the combination he's trying should work. It does sound like an adjustment issue.

Slash5

My mistake, you are correct - the Shimano page doesn't say how many speeds but shows the 590 group to be 10 speed. I'm pretty sure the derailleur would say Dynasys on it if it was 10 speed.

Wressen

So thatīs not the case then. The 10 speed looks quite different from what Iīve seen.


Whats up with the weird hanger for the derailleur. The older deore I have is directly screwed on to the hanger. It does not have that "hinge thingy", the older deore looks like a standard road derailleur mount screw. Is that a problem perhaps?


And yes, I'm using road brifters(Sora 3500).

Is that brake housing you are using?

jimc101

Good spot, + the routing is terrible; that's before you get to the possible incompatibility issues with 9/10 (Dyna Sys) speeds

Wressen

No itīs shimano gear cabel housing.

The routing is what it is, I did not want to cut the housing because the routing to the older deore derailleur need more housing.

And I don't really se how the housing routing would impact me not being able to tune the derailleur when itīs the same gear the whole time. But maybe that is the case. I will try later to se if that improves it.

Itīs not a dyna-sys derailleur, itīs the older generation. As far as I can tell.

jimc101

Getting the routing right will help with the shifting, it really should be as straight as possible as you are using a shadow RD.

If you are using old housing, is this corroded? I find that the RD cable outer will corrode much quicker than any other cable outer due to it's location on the bike.

cobba

You have a 'Shadow' rear derailleur and it shouldn't be the problem.

Shadow rear derailleurs don't stick out a much as conventional rear derailleurs.

cobba

If you aren't using the old Deore derailleur you won't need the longer housing.

The cable housing should look like this:

Wressen

Yes, I'm using the old one since the new one does not seem to work. But I have two bikes that needs a new derailleur.

But I think i might have an old piece of cable housing that I can use to test the effect of a shorter cable housing.

RubberDuckie

Have you tired to run that setup with no gear cable? u would isolate the issue, see that without the cable connected if its still making the same sound on the high and lowest gear.

Wressen

Yes. I forgot to say that. That is my proof that itīs not a cable/housing problem. I could not index it then either.

cobba

Have a look at the derailleur to see if 'RD-M592' is stamped on it, the 9 speed RD-M592 looks very similar to the RD-M593 which is a 10 speed derailleur.

I don't think that the RD-M593 has 'Dyna-Sys' written on it like later model 10 speed derailleurs have.

* post a side on photo of your setup like that last image I posted

RubberDuckie

What chain are you using?

Wressen

SRAM PC-971 if I'm remembering the number correct.

RubberDuckie

Pc 971 is a 9 speed chain... pc 1071 is a 10 speed chain. If you used pc971 on a 10 speed cassete, that could be the cause of the noise.

Wressen

No, itīs a 9 speed cassette, 9-speed chain.

RubberDuckie

Sorry. This whole time I thought it was a 10 speed cassette
