You only train indoors on a smart trainer that already measures power, or you ride Shimano SPD-SL cleats. For SPD-SL, see the Assioma PRO RS-2 or the Rally RS210.
Both quote the same plus or minus 1 percent accuracy. Favero is simpler and works with everything; Garmin adds more cycling dynamics data, mostly useful with Garmin devices.
Garmin lists the Rally as a power meter for compatible Garmin cycling computers and watches. Check compatibility on the listing if you use another brand.
Dual-sided pedals measure each leg directly. Single-sided power is fine for most training, but dual-sided gives left and right balance.
The Assioma DUO listing includes Look Keo compatible cleats. Check the Rally listing for contents.
