guys,interesting discussion,my look...imo Nibali will lose about 2'15 - 2'30 in Saltara TT because this TT is more like 1st TT of Tour12 not the 2nd,probably even more technical and uphill but longer,so just under two and half minute on Wiggins is fine.Important part of the race imo should be the hilly stages where Nibali can do real damage to Wiggins(1+minutes),cos of downhills,crazy attacks,weather etc.

In real mountains he has to pick up at least 1 minute through the whole 3 weeks - imo its hard,but its possible.And on top of that he should pick up 20-30 secs in MTT on Wiggins...if he does this he will be the winner of Giro d'Italia 2013
