MONACO - Seven-time champion Lance Armstrong went out early and put up a solid time in the opening stage of the Tour de France, then was upstaged by Fabian Cancellara of Switzerland.
Provisional results Saturday showed Cancellara with the fastest time over the 9.6-mile time trial, beating 2007 Tour winner Alberto Contador by 18 seconds to capture the yellow jersey.
They led 180 riders who set off one at a time along the winding, hilly roads of the tiny Mediterranean principality of Monaco.
The race against the clock offered an early shakeout of potential title contenders for the three-week race, which covers 2,150 miles and goes through six countries before the July 26 finish in Paris.
