If your Shimano derailleur is bent, broken, or just not shifting right—this video will walk you through exactly how to fix it. I’m working on a donated bike where the rear derailleur is completely destroyed: the cage is bent, the jockey wheels are gone, and shifting is nonexistent.
In this step-by-step tutorial, I’ll show you how to:
😎 Diagnose a broken rear derailleur
😎 Safely remove the damaged derailleur
😎 Install a new Shimano Tourney derailleur
😎 Set your limit screws
😎 Adjust cable tension for smooth shifting
😎 Test the final setup on a repair stand
Rear derailleurs get damaged all the time, usually from tip-overs, poor storage, or simple accidents. The good news? You don’t need a bike shop to fix it. Just a few tools and the confidence to wrench.
