Around 1980, “aerodynamics” became all the rage in bicycling. Certainly, there are advantages in shaping parts to minimize air drag for some riders, particularly time trialists. But studies have revealed that, for the most part, the benefits of aerodynamics accrue only to cyclists riding at more than a certain speed—45 KPH, if I remember correctly.
Still, that didn’t stop bike and component manufacturers from making “aerodynamic “ bikes and parts for loaded bike touring or even “aerodynamic” versions—which looked as if they’d wandered into a vise—of Huffy and Columbia ten-speeds sold in department stores.
Now, it seems there is a trend in the opposite direction. At least one European team is making part of its rolling stock less aerodynamic.
I’m not talking about the bikes. Rather, a new anti-aerodynamic principle is being applied to the team cars and vans that follow riders during major races. Typically, these vehicles carry one or two spare bikes and, perhaps, some wheels and other parts. But, lately, some teams have been stacking five or more bikes atop those cars and vans.
The reason, apparently, is to create a slipstream for the riders ahead of them. Not only does a taller stack, like a higher wall, blocks more wind. But, because the vehicle is moving, it pushes air ahead of it—in the direction of the riders.
As far as anyone knows, neither the Union Cycliste Internanationale (UCI) nor any other governing body has a rule against this practice. If the UCI were to pass such a rule, I have to wonder if it will do as much to deter bad behavior as, oh, their anti-doping rules.
