Nibali’s performances on 5 major climbs in 2014 Tour de France were at the same level compared to Froome last year (also 5 major climbs). I think the difference between Nibali and Froome is that a British rider was more impressive and his attacks more powerful. Contador reached higher avg. power output on major climb in 2009 Tour de France compared to 2013 Froome and 2014 Nibali. Also Armstrong 1999-2005 and Contador 2007 higher power numbers on climbs. Nibali’s values are higher than Pereiro in 2006, Sastre in 2008, Evans in 2011 and Wiggins in 2012
