Display of the currently engaged sprocket only on the rear derailleur. The derailleur index is taken universally from AntPlus (Shimano Di2, SRAM AXS,...). The application is independent of the number of sprockets. The display of the number of teeth on the sprocket is optional in the application settings. When changing gears to another sprocket, the color is gray. The outer sprockets are displayed in dark red. Application use the standard Garmin API for sharing data from electronic derailleur shifting regardless of brand. Localization EN, DE, CZ, PL, SK, IT, FR, HU.
