Voilà monsieur,Christophe said:How does Wiggins know Nibs is going to crack? He still has to ride judging by his own exertion level, not some number that, while statistically relevant, doesn't necessarily apply in the moment, as you pointed out above.
"When we were riding on the front at 450 watts (of power) or whatever, someone would attack and Mick Rogers would say 'just leave him, he can’t sustain it'." Wiggins said.
