Cancellara has 45 lbs on Levi, and assuming his ftp is 6.4w/kg (which is what world record holders put out), that's 280 watts right there. In his case, it may be better to get more watts out and pay a little more price in CdA. That scrunched-up position of Leipheimer sure doesn't look very comfortable.
Edit: got ninjaed thrice over...
the math's a little off, the 6.4 w/kg is kilograms not pounds. So it would be 131 watts.
