Stage 4's team time trial featured a short, hilly, twisty course. Although race officials banned the use of time trial bikes, disc wheels and aero helmets, equipment choice was still a factor.

The teams used their standard road bikes, though many used the deepest-section wheels in their inventory. Race winner Slipstream-Chipotle pushed the limits the furthest, using deep section Zipp wheels and even trying to sneak aero helmet covers past the commissaires.
