I see a few posts on here where people complain that someone overtakes them and then doesn't keep up the speed, which got me thinking about my own experiences. I tend to use the gears so that I am at a constant effort and cadence whether I'm going up hill, on the flat or down dale, varying my speed accordingly. I sometimes encounter cyclists whom I overtake on the downhill when they are often free-wheeling, and then they overtake me on the uphill, out of the saddle grinding away. I'm sure each of us thinks the other is being a pain. What are others' experiences on this?
