I haven't read "Changing Minds".

I have no idea, actually, what gears I should use for gravel + downhill, which is surprising since about 6 years ago I biked from Pittsburgh to DC, which had a fairly long downhill section. I remember mostly coasting on that section. I might've stopped a few times to make sure my brakes could cool down. I don't think there is a wrong gear on a bicycle when coasting down on gravel?

Perhaps I am the user who does need a nightmare bicycle with a gravel + downhill button.
