I fitted a new KMC chain to my MTB commuter as to old one had got to 0.75%, I now get a loud clicking/whirring sound that seems to be coming from the lower jockey wheel (as far as I can tell when it's on the workstand). The noise is there in all gears, and is constant when the chain is rotating, what I mean is that it's there all the time the chain is moving, not just once per revolution or whatever. The idexing is good and changes are smooth. I haven't lubed the chain as it came fairly well lubed, but I will try this.
This is the first time I have changed the chain since I replaced virtually the whole drivetrain last year (including cassette and rear mech), so the bits are only 1 chain old. Is it possible that the jockey wheel has worn out, even though the cassette is fine?
I gave everything a good clean including squirting with muck-off and rinsing, is it possible I have borked the jockey wheel internally somehow?
I thought it might settle down after a few miles, but it's no better after one 20-mile round trip commute. I've changed quite a few chains before, never had this problem though! Any help gratefully received.
