i think the long descent will rule out anything smaller than 4 0r 5 riders,
of the top 25 I think the following will drop:
Porte, he was a way back on the climbs yesterday i cant see him staying
Kiserlovski (not sure), Agnoli, Efimkin, Gerdeman, Didier, wiggins (not sure) Bakelands, Mayoz,
Karpets (used to much yesterday and is not impressive on steep stuff)
Pinotti, De Greef, Cataldo and Petrov
Mollema, not sure if he stays he really will have confirmed his talent
Therefore i predict a group of 10 really but up to three others may fail, notably Arroyo, Tondo and Cunego
I believe Basso is looking very strong but an attack from him should be ruled out as hes not gona stay away on the descent but he will surely be in the final selection
Only one i see winning on his own is Nibali simply because he is unbelievable on descents
