Exactly my point!To be clear it is the power-to-weight ratio that makes the difference. If you loose 2kg that you don't have to lose and end up lacking
the power to cash in on the weight loss then you will still end up at the back. When Wiggins lost weight it was under very controlled condition.
Returning to Pantani it was this ratio that helped him, in the movie he stands nest to Indurain and looks like a midget by comparison
but still beat him up Alpe d'Huez.
