Negative chain stretch?
My current chain seems to maintaining a negative chain stretch of less than 1/16 inch. The chain is correctly tensioned by the rear derailleur (does not sag a bit) and I'm using Stanley branded rule. I even used no-brand made in China rule and gave me the same measurement.
I measured it upon installation from the box and did have negative stretch back then but now, over 1000 miles later, it still had negative stretch. In fact, the amount of stretch did not seem to change at all.
No chain skipping, no issues, no problems just thought it seems weird because the Parktool channel in YT did not mention anything of that sort.
