Migration to 4iiii 

As of July 2021, you will need to download the 4iiii app to pair, link, calibrate, and troubleshoot your Specialized Power Cranks. You should see a notification to download the 4iiii app when you launch the Power Cranks app, or you can find it in the App store or Google Play store.

For more information, see the 4iiii Help Desk at https://4iiii.zendesk.com/hc/en-us/requests/new
