He crashed once by himself in the stage when he also had a mechanical, I posted here a picture with him and the equipment is torn on his right side if I remember. He had to finish the Giro, unfortunately the questionable shape from the beginning degraded towards the end.Yeah, 230km long, with a flat part, then the Monticino climb and Cima Gallisterna (the final climb of the WC circuit) before 4 laps on the Imola WC circuit.
About Nibali, I fear that him rushing back to rushing the Giro and being involved in multiple crashes (he never directly hit the deck himself, but was hit by other riders who where coming from behind in both his crashes during the Giro) but still wanting to finish the Giro pretty much ruined the chance of him being in good shape for the WC.
After he broke his wrist, as much as he wanted to be different, everything went downhill. Not sure what can be done for the Olympics, the idea to skip the Tour and prepare a fall resurgence seems a good one.
About next team, rumors still point to Astana in pole position.
