It means calm and reserve to me, perhaps coupled with a careful observation of one's manners. It's not exactly a manner of dress or speech- more a way of behaving. Bashfulness and modesty doesn't bring anything but good.
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.
At 30 years, six months, the average age of Tour winners in the past 10 years skews slightly older, thanks to Lance Armstrong (32 to 34 when he won in 2003 to 2005), Carlos Sastre (33 in 2008), Cadel Evans (34 in 2011), and Bradley Wiggins (32 in 2012). THE BOTTOM LINE: The average age of Tour de France winners is 28 years old. But that doesnât mean that guys in their 30s are destined to domestique-dom. Firmin Lambot became the oldest winner at 36 in a Tour that ranks among the longest courses ever, covering 3,340 miles in just 15 stages in 1922.
