Garmin has started pushing a new beta software update for its latest generation of cycling computers. Just five days after releasing beta version 33.20, the company is now rolling out version 33.21 for the Edge 1050, 850, 550, and Edge MTB models.
This release comes as a quick follow-up patch designed to resolve specific performance glitches introduced in earlier test builds.
Fixes for Power Calibration and System Bugs
- Fixed repeating power calibration prompt.
- Improved device stability.
The primary focus of version 33.21 is fixing a frustrating bug that affected riders using power meters. In previous software versions, cyclists were repeatedly hit with power calibration prompts throughout their rides or every time the device booted up. The new patch eliminates these persistent pop-ups so power data syncs cleanly without interrupting the screen display.
In addition to fixing the calibration prompt issue, Garmin applied broader system stability tweaks under the hood. The update strengthens overall system reliability across all four supported Edge models, lowering the risk of sudden software crashes, screen freezes, or sensor drops during live activities.
How to Install the New Update
Riders participating in the official Garmin Public Beta Program can download version 33.21 over the air directly to their device.
To get the download started, make sure your Edge unit is connected to an active Wi-Fi network. From there, open the main menu on the screen, head into System settings, select the About section, and tap Check for Updates to pull the software directly from Garmin’s servers.
