Shoulder-width, bar-width and how to measure.
So I've seen written a few times that handle bars should be as wide as your shoulders. Makes sense, but my question is... how do you measure shoulder width? Is it the width between your shoulder blades? Or the width if your shoulder bones at the top of your arm?
If it's the latter, then apparently I need a drop bar 52cm wide... which are simply not available. I have broader shoulders than average but I didn't think I was anything too out there.
