Clicking from the cassette/jockey wheels

[Gruffy]

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?

I have done this and it looks right. I'm new to bike maintenance though so I'm sure there's room for improvement.

Makes very good sense. I'll have another tinker. Thanks.

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.

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.
