Nibali headlines Giro amid mechanical doping concerns (The Associated Press)

Vincenzo Nibali knows exactly why he struggled so much last year, and this year the Sicilian is determined to return to cycling’s pinnacle when he lines up as the main attraction in the Giro d’Italia, which begins Friday in the Netherlands. Nibali’s 2014 Tour de France title made him the sixth rider to win all three of cycling’s Grand Tours – the others being Jacques Anquetil, Alberto Contador, Felice Gimondi, Bernard Hinault and Eddy Merckx. ”At this time a year ago I was struggling,” Nibali said.
