Reviewed - Single sided Power Meters

All the power meters featured in this category acquire their power measurement from one side only. These power meters provide an average total power output by doubling the power output from the measured leg. What can’t be measured with these power meters is LEFT and RIGHT power balance. The best way to do this is with power meter pedals or one of the other double sided power metering systems.

However, for a vast majority of cyclists this averaged power figure is more than adequate. These single sided power meters are some of the most popular on the market due to their ease of fitting, accuracy and low price (compared to pedals/chainring power metering systems)
