Also note that the Power2Max power meters do not give “real” L/R balance readings. Here’s an excerpt from DC Rainmaker’s review of the NG Eco:
"So why don’t I care about left/right power balance (which the ECO lacks)? Well because in the case of how the Power2Max measures it, it’s not real. It’s actually not left/right balance, but rather whether you’re pulling up or not. You can easily trick this by simply single-leg pedaling, and you’ll note the unit totally misses that. Compare this to true left/right balance capable units like the Verve Infocrank, ROTOR 2INPower, PowerTap P1, Garmin Vector, Favero Assioma/Bepro, and so on – which actually measure the left and right sides.
As such, since it’s giving you useless power balance data – then it honestly doesn’t matter. Plus, I virtually never look at power balance data when doing ride analysis. The only place I think that’s valuable today is injury recovery, and in that case you really want to have legit left/right numbers."
