Agreed. I understand being "competitive" and this is a race, but it is an unwritten agreement amongst "gentleman". You don't gain time on an opponent who has a mechanical issue, especially when it happens right in front of you and you've been evenly matched all day.
Never been much of a fan of Contador, and I know he'd probably have made up the time over the next few days, but he seems like more of a jerk than ever, now.
In all future editions of every Spanish dictionary, the definition of the word cabrón should be illustrated with a picture of Alberto Contador taken on July 19, 2010.
