I think I was about to round a tight left turn where the photographer was standing when that picture was taken so I wasn’t as tucked in as usual. My point is, the TT bike itself is much more aerodynamic than a road bike, and it allows you to get your body down lower, out of the wind. When I ride my TT bike I’m usually going at least 2mph faster over the same routes I ride on my road bike. (22-25mph on the TT bike vs 20 on my road bike) with the same amount of effort.
