I'm not sure if a Garmin employee will actually see this.
The Edge 130 Plus is awesome! It may be easy to think of this as an entry tier device, but the fact that it's so small and lightweight makes it an outstanding choice for competitive athletes that are looking for data/metrics to improve their performance without adding unnecessary weight or bulk to their setup. With this in mind, the lack of support for electronic shifting is a pretty serious oversight for the 130+. The hardware is clearly capable of performing this, because the eshift130 app by ekutter has proven it. While this app is great (seriously, the app is fantastic), it also has its limitations, including not recording gear usage for the duration of a ride/activity. I respectfully request that this enhancement be added in a future firmware update.
Thanks for your consideration.
