Chain fell of Derailleur ...

puresav

chain was skipping a bit.
I thought indexing was off, then I geared down and then the chain fell of my rear derailleur in a way I have never thought possible.
pictures in the next links





I managed to put the chain back in using the tire lever and expanding the derailleur.
it felt like i was violating the rear mech...

needless to say, the chain still skips,
So is my rear derailleur dead?
any thoughts? tips?

I'm not seeing any pictures.

Unfortunately without them your explanation makes little sense.

k-dog

I can't see the pictures.

How old are the chain/cassette? Have you checked the length of the chain for wear?

cooldad

Bit of a PITA but if you 'quote' and follow the links, you can see the pics. The chain came off the lower jockey wheel and caught between that and the cage. Possible low chain tension (small/small type ratio), and a bump in the road.

Or worn bearings/loose jockey wheel.

Why it needed a tyre lever to fix I'm not sure.

Is the derailleur/hanger bent?

WTH is the gear cable doing? It exits the cable stop then bends through 90 degrees.

I can't see any pictures either, but I can snoop through source code, and paste them in





EDIT: well that was a fail and half, I hope it works this time

as above, that cable path just looks wrong, couple wider shots showing the rd side on and from the rear might help (with the chain on and wheel mounted

i think the images aren't working as the service is generating url per user, i.e. whoever pasted them can see, but no one else can

That's getting worse - now you can't even just look at the link in the code.

sungod

yeah, i tested and then edited to remove them, it's google generating per-session links, presumbably to avoid people using it to share this way

op, use postimage.org instead, no need for a login, just upload

Here are the original images






Agree it would be better to have some wider angle shots from side and rear - how about it OP

And, another fail.

You can't hotlink from Google images.

cooldad

But it's amusing until the OP returns...

Only time I've seen that happen is with FUBAR lower jockey wheel bearing/bush, it can be very expensive!

As above - WTF with that cable line from the stop to wherever it goes!

Thought it was all about not being able to embed the OP's original images into the post. I just right clicked the little "Image" rectangle in his original post and selected "Open image in new tab". Once the image was there in a new tab I right clicked it and selected "Copy image address". I then pasted this address between the [img][/img]

sungod

because it doesn't work - you can see the images ok, but no one else can

fwiw i did the same as you describe, i can even see the images in my post that was quoted by k-dog, no one else can though!

if you've got chrome, open an incognito window and view your post

cooldad

Because we can't see the pics...

cycleclinic

could the jockey wheels be worn. look for spikey teeth or no teeth.

cooldad

Look at the pictures and see.

Weird. Worked when i originally edited, now logged onto a different computer and it's all f*&ked up again.

Edited post, should work now

I can see pics. Gears might work better with back wheel in and bike up right way; it'll certainly ride better.
