For years, bicycle makers have squeezed more speed and efficiency out of their products by shaving weight to the minimums set by cycling's ruling bodies. But to really improve a bike, whether it's for riding in the peloton or the park, you have to reduce aerodynamic drag.
Victories in this constant fight are measured in fractions of a second saved per kilometre. Tiny improvements to be sure, but they add up quickly during a 40-kilometre time trial or a 200-kilometre stage of, say, the AMGEN Tour of California. But you don't have to be Bert Grabsch or Sylvain Chavanel to benefit from this. Aerodynamics is, at the bottom line, about making it easier to go further or faster while riding more efficiently and comfortably.
