Cog Display


This app calculates the gear ratio that you are currently using based on your cadence and your speed. Since it is impossible to determine what chain ring you are using, the app will display all the estimated cogs. For instance if you have a double chain ring 34/50, it will display the estimated cog for the 34 chain ring on the left and the estimated cog for the 50 chain ring on the right. It wo...

What’s New

Bug fix (1.0.4): On Edge 520, the display was very small. I believe it is now fixed with this version, but it is hard for me to test it since this bug does not appear in the Garmin simulator.

J'étais un peu septique au début au téléchargement et puis après 3 secondes d'utilisation bluffé marche..... génial quand on voit que pour avoir un capteur certe avec plus d'info mais chez shimano pour le DI2 c'est 80€ génial

Increíble! Aunque me gustaría recomendar una mejora estética en el sentido de que el título de la cuadrícula y el dato ofrecido deberían estar separados, así como aumentar el grueso de la fuente.

Bluffant ! Apporte vraiment une information supplémentaire et intéressante sur le Edge. On passe une vitesse et en moins de 2 secondes le nouveau braquet est affiché à l'écran. Fini de devoir baisser la tête pour regarder sa cassette. Je recommande vivement. Bravo et merci au concepteur pour ce partage.

The app work well, I have the only problem that I can succeed to save my chainring and cog. I modify them but every time I connect garmin 520 i found the stock entries.

Hi Nico, Sorry about this, that's an issue to address to Garmin actually. I suggest that you use always the same device when you sync your Garmin. For instance, if you use only your phone, you can change the settings on your phone in the Garmin app. If each computer and each phone that you use has the correct settings then it should fix the problem.

The app worked very well on my Edge 520 (running v10). The label and numbers didn't quite have the same spacing in a five-row page as the built-in data fields but it was close enough. The update to v11 appeared a few days ago and after loading that, something broke with this data field. I deleted and reinstalled it and the issue persists. The small ring field shows only 000 while the large ring field is displaying a number with a decimal place.

Hi, Sorry about this, I suspect your settings got screwed up. Can you try to reset your gear teeth etc?

Genius! Accurate and responds very quickly to gear change.

All is OK with my edge 1000, 50X34 11 v 11-28 La première appli du genre qui fonctionne !! Thank you

Très sceptique lors de l'installation, j'ai été bluffé lorsque j'ai testé cette application lors de ma sortie du jour. Lors du changement de pignon, 2 secondes suffisent pour que mon Garmin affiche le bon rapport. De plus, chaque fois que j'ai contrôlé le le pignon par rapport à ce qu'affichait mon Garmin, c'était juste! Bravo à son développeur et surtout merci!

Works great on my Edge 1000. Didn't need to count the teeth on each cog of my Dura Ace cassette. Shimano publishes that information: Simply click on your cassette and then on "Detailed Product Page" where it lists each "Sprocket Size." Shimano shows detailed cog information for Dura Ace and 105 but, oddly enough, not Ultegra. Possibly the cogs for Ultegra are the same as for Dura Ace (although there's no Dura Ace 11-32)?

So far I have not found any problems with the Edge 1000, works perfectly and is very visible in any size of field.

Sorry, no statistics available yet.
