Clicking from the cassette/jockey wheels
Discussion
Can anybody offer advice on how to diagnose the problem I'm having?
I've just replaced the rear derailleur cable on my Triban, which went perfectly well, but now there's a pronounced clicking/ticking from the rear when pedalling. It's not there when freewheeling, only when the chain is in motion and getting louder the faster I pedal. I can't see the chain contacting anything at any point, anywhere. The indexing seems fine too.
Any clues?

Well if the only thing you have changed is the cable AND there was no jockey wheel clicking before you changed the cable, then the only rational conclusion is the tension you have set the new cable is not the same as it was before.
It sounds like you need to fine adjust it until it is back to the perfect length (tension).
N.B. Even a quarter turn of the barrel adjuster can make the critical difference.

Start by making sure your hanger is straight. You'll either need a tool to do this or 5 mins in a bike shop. I spent hours on mine over the course of a weekend, eventually giving up in favour of bike shop help. Chap straightened out my hanger and it all came together very quickly and simply.
I've bought myself a tool to do my own now.

Had a clicking noise from the back wheel, turned out to be one of the cogs in the rear mech intermittently seizing and the click was the chain slipping over it.
Annoyingly enough it mostly behaved on the maintenance stand
Took ages to get to the bottom of that one, mech replaced in its entirety under warranty at 160 miles when I finally worked it out.

The chain is in good health. It's relatively new and passes the chain measurement tool. The clicking is constant and in proportion to the speed with which the chain passes through the rear. It isn't limited to one part of the chain.
I'll check the hanger but as the clicking only appeared after changing the rear cable it makes most sense that my indexing isn't as slick as I'd like to think. I'll have a tinker now and report back.

I've fettled the indexing and twiddled barrel adjusters. They were making the noise louder and quieter so that would seem to be it. I've made it as quiet as possible before running out of adjustment. By this point I'd lost all sense of perspective as to what noises were normal and what weren't. I'll take it for a quick spin tomorrow to check but I think I probably need to close all the barrel adjusters right down and then take in the slack before starting again with a bit more range on the adjusters.

Is the end of the cable touching the chain? I've done that one before with front derailleur cable and pedals. Took me ages to find!
Ahhh! The old "gear cable fouling the pedal cranks" clicking at the front derailleur. I've had that one too, and much like you, it took an absolute age to work out what the blazes was causing it.Watchman said:

You can also do this reasonably well by screwing a spare wheel in place of the mech.I've bought myself a tool to do my own now.

This was it. I loosened the cable, reset the adjusters and the started from the beginning. Then I had enough left in the adjusters to pull in the slack and fine tune things. I just went out for a short spin to check things out and bagged a cheeky KOM so I'm taking that as a sign I've done a fair job.Thank you all for your advice.
