At this point in my training I just need basic power measurement. I don't need the refined measurements individually for left and right legs or a power value that is 100% accurate. The Garmin Rally RK100 single sensing fit the bill. The power measurement I get from actual bike riding seems to match well with the values I get from my Tacx trainer. That is to say that the same amount of perceived effort seems to register the same power values on either.
The single sensor power pedal is good for me
I gives me good feedback at a reasonable price
This is a great alternative to crank-based power meters, and easier to install/swap with other bikes. Haven't had any problems so far. No noticeable difference from my older Look key carbon blade pedals.
