ERG mode is a setting where a device controls the resistance of the bike based on a preset target (such as 150W). This mode can be utilized to maintain a consistent output with changes in cadence. It's most commonly used to perform a prescribed workout that calls for power targets for each interval. We recommend ERG mode for nearly any workout, except those that call for short efforts, such as sprints or any efforts under 30s. Sudden bursts of power or acceleration are not ideal for ERG mode, so we suggest turning ERG off for these efforts. 

ERG mode can be engaged within an app such as the Stages Cycling app, TrainerRoad, or Zwift (while using the workout feature) or by your head unit. Most preset workouts set the target as a percentage of your FTP. Before using ERG mode to complete a workout, ensure the correct FTP is set on your device. 

ERG mode in the Stages Cycling app

From the Ride tab in the Stages Cycling app, select the StagesBike tab and tap on the control mode icon and make sure the lightning bolt icon is selected. Adjust your ERG target with the slider (color-coded by zone), then make micro-adjustments with the +/- buttons.

To complete a workout in ERG mode, select the Workout tab and pick a workout from your scheduled workouts (workouts on a calendar synced to your Stages Cycling app account, such as Stages Link or Training Peaks) or pick any workout from the Stages library. 

ERG mode on the Stages Dash

When using a Stages Dash with your StagesBike, ERG mode can be engaged from the Trainer control page. Press the select button and toggle the setting to the lightning bolt icon, then use the arrows to adjust the ERG target. 

If you've loaded a workout, the bike will be in Erg-w mode and you can adjust your workout targets using the same Trainer control page. Use the select button to toggle the selection to the barbell icon and use the arrow buttons to adjust the target up and down in percentage.
