But for the Tour I see they are only running the non drive side.

These are rubbish IMHO, they are using wind speed and accelerometers as a calculation so if you do a session indoors then it doesn't have anything to factor in...unless you get the indoor package upgrade...?

 

Rather get a PowerTap POwerCal heart rate strap, still not 100% accurate but certainly a LOT more accurate than the ibike thing...I have had results within 3% compared to a direct measurement hub system on averages.
