Ergomo Pro power meter
I might write this puppy up in detail at a future date. For now, let me just say that after 9 months of use, the Ergomo Pro power meter has really grown on me—without a doubt the most useful training tool I’ve ever used, and in spite of having to run the irritating Cycling Peaks software on Windows.
Why do I still use the Polar S720i? It offers slightly different data, and is useful for skating, running, etc, so it’s a catch-all for tracking all workouts, not just cycling ones. Plus it’s easier to deal with intervals on the Polar, and the Ergomo temperature readout is often off by 3-6°F.
