Myths in cycling: wider tires are slower
Case on aerodynamics is weak. I realize their analysis might make sense for extreme endurance events, but they don't generalize to road cycling. They did not test at common race speeds for cyclists. It's 5 watt at 30km/h. That might mean 14 or so watts at 50km/h. It doesn't seem like much but that's significant enough in a road race. And then there are sprints that take place at 60-70km/h
