Clothing can't be ignored at the Tour de France as the rider's body presents the most surface area - and thus the biggest potential for aerodynamic gains.

As the 2012 Tour de France heads to Paris for its finale, we'd like to show you the bikes that the pros have been racing around France for the last three weeks.
We've already shown you many of the time trial bikes - which will again be used in today's 19th stage - but most of the race is ridden on road bikes.
In the first part of this two-part gallery, we'll run through Ag2r-La Mondiale's Kuotas to Liquigas's Cannondales. Simply click on the gallery at right and let our eagle-eyed tech editor James Huang give you a real insight into the machinery underneath the riders at the Tour.
