Hi all, i have this wear indicator and i am unclear what it exactly measures. I have a 11 speed chain that i am trying to measure and it almost fits. On other wear indicator tools i see they put 0.5 % / 0.75 % / 1 % annotations on it, that would have been helpful here too.
I looked at the documentation but it is not mentioned. When i put it next to a ruler, it think the indicator length is about 89mm.
