Garmin rally RS100

The Garmin Rally RS100 is a single sided power meter. A single-sided power meter is often cheaper to purchase than a double-sided power meter. This is because the power is only measured on one side. This measurement is doubled to calculate the total power delivered. It could be that the wattage supplied on the racing bike differs slightly per side. That is why the measurement of the double-sided power meter is even more reliable. In addition to power, this power meter also measures cadence.

Nice to know: Do you own the Garmin Rally RS100 but do you want a dual system with two sensors? Then you can easily upgrade. You then purchase a Rally RK100 upgrade pedal.
