I have a bike with a 2x10 drivetrain; however, I noticed that the chain rings are "9 speed" chain rings.
Does this matter?
I realize the 10 speed chain is a bit narrower. Will the 9 speed chain rings be too wide / cause excessive wear or lack of smoothness?
Or does it not really matter all that much?
