How to Fix a Shimano Derailleur (Even When It Looks Like This)

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. 🛠 Tools & Components Used in This Video Linking to Amazon: Shimano Tourney TY300 Rear Derailleur 👉 https://amzn.to/3INSO9k Feedback Sports Pro Mechanic Repair Stand 👉 https://amzn.to/44QTIul Park Tool Derailleur Hanger Alignment Gauge (DAG-2.2) 👉 https://amzn.to/453skYN Hex Key Set (Amazon) 👉 https://amzn.to/4lJoeMA Shifter Cable & Housing Kit 👉 https://amzn.to/3H6BCeA Park Tool CN-10 Cable Cutters 👉 https://amzn.to/3IQFWiI Bike Chain Tools 👉 https://amzn.to/46s188B 💬 Questions or stuck on a step?
