An aspect I admire about the Tour de France is the respect and sportsmanship between the riders. Riders obey many unwritten rules for the sake of sportsmanship.
One of these rules is that you do not attack when or if the Yellow jersey has a problem.
In 2010, Contador took advantage of Andy Schleck's mechanical problem on the climb.
In 2013, Contador thanked the Team Movistar riders for not waiting after he caused Froome to go off the road.
Sorry, Alberto, you might be an excellent cyclist, but you are terrible sportsman !
PS: When you are finished with cycling, you should join the Australian cricket team.
If you are lucky enough to have DSTV and follow the Tour de France, then the best commentary and insights are to be found on DSTV Channel 431 - BVN
It is in Dutch, but with a working knowledge of Afrikaans you should be able to follow.
They do use some strange words, like "ploeg" for "team" but you quickly pick it up. in any case, most of the Dutch cycling terminology is borrowed from French, for example they would use "etappe" for "stage"
The have very knowledgeable studio guests, ex and present riders, ex and present team leaders. Listing to them even highlights how uninformed Paul and Phil are.
It also comes on late at night when there are no contests for the remote, else use the PVR.
