intermittent ting-ping- issue.
I have an intermittent ting-ping noise on my Surly LHT. It seems to be coming from the crank area. It is happening quite often but seems completely random. It happens in any gear combo and is not coming from the derailers. I have just changed cassette and chain. I can't get it to repeat itself while on the bike stand. I would appreciate any ideas about what it could be or how to find the issue.
