how much do tour de france riders weigh
The Rca frame and basic hardware weigh less than 1.5 pounds, keeping the bike's total built weight to about 10 pounds. Tour de France riders must add ballast to hit the race's 15-pound minimum. Drag consumes up to 50 percent of a racer's energy when he's in a pack, 90 percent when he's riding alone. The tubes of the Rca frame are teardrop-shaped in cross section, improving aerodynamics.
