WATERLOO, Wis. -- A small town in Wisconsin helped Lance Armstrong to one of his biggest victories.

Armstrong won his fourth straight Tour de France on a Trek bicycle made in Waterloo, Wisc., just west of Madison.

Armstrong, who called his bike "mean and fast," rode an 18-speed, carbon fiber cycle to his second-largest Tour victory, finishing 7 minutes, 17 seconds ahead of Spain's Joseba Beloki.

The 30-year-old cancer survivor and Texas native is within one of the Tour record of five titles.

Armstrong's bicycle weighed less than 16 pounds, and he is one of nine on the U.S. Postal Service team racing with Trek bikes.

"The Tour is the ultimate test for a bike company," Trek President Mark McCubbin said.

Trek USA, which began in 1976, is the No. 1 bicycle manufacturer in the U.S. and produces more than 500,000 titanium, aluminum and steel cycles a year. The company also concentrates on a lighter fare specifically made for the pros.

Armstrong gave this evaluation of his bike to the company -- "The only problem is for the other guys because this bike is mean and fast."
