Yes that was an interesting explanation, and makes sense for this situation.

Of course I always think it's good to remember now and then that probably 90% or more of the world's active bicycle riders are neither leisure OR competitive riders- but are riding their bikes for basic transportation and for transporting things. Few of those people ride with their handlebars lower than their saddles- they ride mostly upright and they really lay on the miles on a daily basis. These are serious bike riders, not leisure riders (as most of us actually are). They would be bewildered and bemused by all our endless fussing about aerodynamics, knee position, CO2 cannisters, clipless shoes, aerobars, and carbon seatposts. I like thinking about this from time to time to put bike riding in perspective in my mind.
