Tour de France: Top-five general classification contenders

There’s much uncertainty leading into the 2012 Tour de France, with recent injuries and quiet showings throughout the season catapulting some of the favourites into the ‘unknown’ category. Alberto Contador is of course absent from this year’s race and this may instil confidence in a number of contenders, while others will hope to turn around a year of poor form. Some, like Bradley Wiggins will be arriving back at the Tour after being forced out last year in the crash-marred first week or from skipping last year’s race.
