"Auditory hallucination" is the best term I have for it. Then it's time for a break.
On normal days, if I start hearing excessive chain noise after checking and maintaining things, that's my clue I'm wearing out a chain ring.
If many of my customers claims were correct the noise starting after a number of miles is because the bike got warmed up, really this has been claimed by many over my years of shop work. I wonder if it's more because the rider is getting tired and more ragged in their form. Andy
