Reviewed - Dual sided Power Meters

All the power meters featured in this category can measure power from both sides. These products offer true bi-lateral power measurement with the exception of the PowerTap C1 which estimated left versus right power contribution. If supported by the monitoring device these power meters can provide feedback on LEFT and RIGHT power balance. These top end power meters are capable of calculating a TRUE Total Power figure as both legs are being monitored independently.

If monitoring the power generated by each leg is a little OTT then I’d recommend a SINGLE sided power metering system, often almost half the price of these dual metering systems.

    4iiii Precision Dual sided

    This is the dual sided power meter from 4iiii with strain gauges hidden away in both LEFT and RIGHT crank arms.
