contador assumed the race lead after winning the ninth stage to mount etna. contador continued to increase his advantage by riding well in the remaining stages and winning the stage 16 individual time trial, which allowed him to win his second giro d'italia championship. contador raced the 2011 giro despite having an ongoing trial about his possible use of clenbuterol, a banned substance. on 6 february 2012 the court of arbitration for sport decided that contador should lose his 2010 tour de france title and his results since that race, which included his giro victory in may 2011, and receive a two-year ban. after contador's conviction, runner up michele scarponi was then delegated the overall victory.
