Front derailleur isn't working, noisy motor, broken arm...

A two part guide how to repair Shimano front derailleurs FD-RX815, FD-R8050 and FD-R9150.
In the first part I'm fixing a faulty servo and in the second a broken polymer linkage.

As 11 speed Di2 components becoming more scares, I think more people will try to repair their broken components. Either fix it, or face inflated cost of replacement components, or upgrade to 12 speed. Whatever you choose to do, repair is always worth a shot!

Please take extra care when working with power tools, knives, and soldering irons. Always wear appropriate PPE. If in doubt, please contact professional.
