According to the product specialist
Pros
Mounting is easy. |
6x stronger signal, so reduces the risk of interference |
Cadence measurable through magnet. |
The AA battery in this power meter lasts very long and is easy to replace if needed. |
The crank is very rigid and light. |
You can choose the set-up. |
You don't need a magnet for the cadence measurement. |
Compatible with Shimano SPD-SL cleats. |
The Garmin Rally RS measures advanced data, including power and performance analysis, cadence and left-right balance. |
The sensor shaft can be transferred to other versions of the Rally (XC or RK) and Vector 3 pedals. |
Full integration with the Garmin Ecosystem, including Garmin Connect, Edge cycling computers and Garmin sports watches. |
Available in a single-sided version and a double-sided version for the most advanced and accurate measurements. |
Cons
Single-sided measurement doesn't give the complete picture of your effort. |
This meter only looks nice at a Dura-Ace R9100 crankset. |
The measurement is one sided giving a less exact representation of total power than a double sided power meter. |
Has no internal battery, so you will need to replace the button cell batteries from time to time. |
