Other Factors to Consider
Some riders may prefer one brand’s user interface or app over another. We recommend downloading apps like Garmin Connect or Wahoo ELEMNT Companion to see which would best suit your needs.
If you are considering using a heart rate monitor, power meter pedals or an indoor trainer, it may be helpful to find a brand that you would like to use across all these products. Of course, these products will work across different brands, but using a singular brand can streamline the data analysis and remove communication variables from using different brands.
It can also be helpful to consider compatible computer mounts. Each of these computers will use a different mounting interface which means a computer mount must be specifically designed for.
