"False shifting" I'm stumped...

[Panter]

I think thats what it's called isn't it? the chain keeps half shifting to the next cog up and then back down again.

I thought it was a dodgy cassette, but I've just fitted the new one and it's no better.
The chain looks Ok, no obvious kinks and it's fairly new.

Only thing is the jockey wheels seem to have a fair bit of play in them, could it be that?

Indexing needs some attention is my guess.

I think it's unlikely to be jockey wheels. Unless they are the jobs with bearings in them there will be a bit of play.

 

[Panter]

Ok, thanks for that. I've just checked the Enduro actually (brand new derailleur) and that has some play too although not as much as this one.

I've followed this guide for indexing, as I always do, but it just doesn't seem to be working.

Derailleur alignment? Are both jockey wheel directly vertical beneath the cog?

Checked for play in the rear hub?

dodgy Free hub causing the cassette to wobble

Cables or Cable outers have had it

No, no play at all.

Doesn't seem to be any wobble in the cassette now.

New cables unfortunately.

I think Palinurus had it actually, there's a problem with the shifter.
If I feed the cable into it, and hold it under tension, it shifts the cable in and out smoothly without fault.
As soon as I reassemble it all, it sort of half-jams and doesn't click smoothly up and down.
There is a very slight kink in the new cable where it goes over the nylon roller in the shifter, could this be the cause of the problem? it is a very slight kink.
Should I get another new cable or admit defeat and get it into the LBS?

Thanks again for the help

once you've exhausted what you can do with your own/borrowed knowledge and tools, the lbs is the best option, if you have a good one.

 

[Panter]

Thanks for that, at least I've tried everything.

Well, nearly everything. I'll grab a new cable from Halfrauds on the way home from work just in case it is that.
I hate being beaten....

You deffo adjusted the cable tension because I've had that commonly and it was just cable tension adjustment that sorted it.

I think thats all Ok.
As I say, I followed that youtube guide and I've never had any problems doing it that way before.

Really? Some grown men pay for that sort of thing at the weekend... so I'm told.

Not me, I have a natural pain allergy

If I'm exposed to pain, I get all angry and flustered
