Clicking noise on biggest cassette gear
I have a Ultegra SL rear derailer, it is a 20 speed bike.
The bike shifts smoothly and is quiet except for when I am in the smallest ring up front and the biggest gear on the cassette. Does it a little less when in the big ring up front.
Then it makes a clicking, almost baseball card in the spokes sound.
I cannot replicate this on the stand, it has to be when under a lot of power. I cannot replicate it by pedaling backwards.
I removed the plastic spoke protector thinking that could be it.
The bike is a few months old and just started doing this.
Anyone have an idea?
