is this chain borked?

[Salty seadog]

Afternoon all, out on a ride the other day all of a sudden my chain started to try and jump gears, it was only on the higher 3 gears on cassette and happened on both chainrings. It was every 5 or so rotations of the peddals and upon checking today i found one link with bent outer plates.

It is when this gets to cassette that the chain wants to skip.
Is it borked or would some plyers do to try and straighten it. I have a feeling the chain may not be the correct length as I can't get thetop jockey wheel closer than about 10mm from the cassette when in big ring big ring combo. Would my thinking be right with this? It also looks like the derailleur does not hang straight in the big ring in some gears.

Any thoughts out there?

Many thanks,

ssd.

Ok , all sensible answers which i agree with. No idea how it's happened and although i'm ....aaahh..eerr 15 stones, i almost never get out of the saddle and have always been concious not to put too much strain (in my opinion) through the drive train. Cannot have done 500miles on it yet, probably a lot less.

It just happens. I snapped the chain on a brand new bike that had just about done 15miles once.

If you are mean and the chain isn't too worn just take out that link.

If it is relatively new, just replace that broken link with a removable link.

That link popped off its rivet most likely because of a bad shift under power. Like the others said, don't ride it. That open Y is just waiting for the right moment to catch on the rear derailler and rip it right off the frame, into the rear spokes.

As the others say.

Somethings in life needs "Balls" to do, if I rode on that chain and it snapped whilst going up hill, I'd be wishing that I did not have any "Balls" to have attempted it.

In the bin.

Thanks for the further replies, @User9609 chain is joined with a quick link and measured at only .5 wear measured in 3 different places. @Yellow Saddle , you always present sound advice to my mind, if I did replace with a quick link I don't suppose it matters that it would then have two on it?

Replace it you tight-git!

No it won't. You can build an entire chain from quick links if you have enough money. Well, half a chain in anyway since you still need some "slow" links.

I'm not sure what 0.5 wear is, probably a proprietary unit from one of the chain measurement tools?

Yes .5 on a park tools chain wear tool, I believe it is a percentage value.

Probably not a good idea to ride a bike with a chain in that condition
Especially if you are planning to have children in the future.

So two thirds of the way to replacement, assuming wear is liner. (whole new can of worms)

For the sake of a tenner I'd replace it, as a ball saving temporary measure I'd take out the bust link.
