Here is what I don't get about Tri athletes and cycling. Why do so many/all tri athletes use aero bars to train and also in races? Most of their training around here is on roads with lots of cars, winding twisty roads, uphill, downhill, downhills with curves. What the heck advantage do aero bars give them on such roads? They're not doing TT on an isolated fairly straight road. And the races 'round these parts on on those same hilly winding roads. Just the places you don't wanna use aero bars. Is it kinda requirement and clique thing. Tri athlete = aero bars even though the training and competition is on hilly road courses more suited to normal road racing set up?
