Ketchell himself admits that the rider produces the bulk of the total aerodynamic drag – roughly 80 percent, in fact. But while common sense would then suggest that rider position should be the main focus in the wind tunnel, Ketchell says the opposite is true. Given the UCI's increasingly stringent rules regarding such minutiae as arm and saddle angle, equipment optimization has actually increased in importance, particularly for time trial specialists whose positions are already highly refined.

"Equipment is really where we can pick and choose and make sure we have the right bearings, make sure that crank length is correct, make sure wheel and tire choices are right, handlebar and water bottle placement, everything," he said.

According to Ketchell, the five most important equipment categories are the frame, clothing, helmet, wheels, and tires, with nearly 30 percent of recent gains coming from the team's latest skinsuits on account of the enormous surface area involved. The other four categories in total combine for another 50 percent or so with other smaller factors filling in the remainder.
