Everything is lighter and stronger, and computer technology has made it possible to fine-tune bike and rider to an amazing degree—particularly female riders’ breasts. Due to a law enforcement neck injury, my bike racing days are over. I can’t get on the drops (the lower portion of road bike handlebars)—it’s a pain in the neck--so I ride recumbents. In bike racing, the tiniest technical detail and rule is usually rigorously observed. Female riders tend to be among the leanest female athletes in the world with very low body fat percentages, which means less - ahem - prominent breasts.
