Sigh. Once again.
Nieve, the Euskatel domestique came into the climb with a 2 32 minute lead. Usually a 2 minute lead will evaporate quickly on such a clim. Yet Nibali came in 1.56 behind Nieve. They were always around the 2 minute mark behind Nieve. In other words Kreuzigers "super pace" was only sufficient to take half a minute from Nieve, while we would have expected a high pace to catch Nieve.
Which leads us to 2 options.
1 Nieve is a super climber and Euskatel made a mistake giving the leadership to Anton and not him.
Or far more likely 2 - Kreuziger wasnt going as fast as you make out.
