Don't misunderstand me either Quinn8it. I am not anti Stages and appreciate your review - being a power junkie (now own 4 SRMs ) I am keen to look at a Stages in the future for my MTB...

But given the suggested limitations with measuring one side only and doubling the data due to fluctuations with L/R balance across efforts and fatigue levels, one really beneficial use of a power meter is not possible; that of field testing aerodynamics. I have spent a day in the wind tunnel years ago and found the wattage savings amazing. I can't afford to go into the tunnel everytime the UCI forces us to change equipment or when I try something new with my position or equipment!

As an aside - first issue I have had with one of my wired units was on returning from the States recently was the coil broken in numerous places. Not sure how the luggage handlers managed it as the bike was well packed in the case. Local guy checked it over suggesting it was the circuit board so it was sent to NZ (we don't have a service center in Australia ). Something not necessarily advertised as they would rather have you buy a new unit, but with some wired units they can swap in a wireless circuit board...
