Ask a Mechanic: Shimano Di2 Crash Recovery Mode

In this episode of Ask a Mechanic, Greg O'Keefe talks to us about Crash or Protection mode with Shimano's Di2 groups and how to fix it via the system's Crash Recovery Mode. When the derailleur is impacted hard enough, the derailleur will disengage from the cage and prevent the system from shifting. Putting the system in Crash Recovery Mode and resetting the rear derailleur is usually just what the doctor ordered.
