FAQs

What tools do I need to replace the inner plate?

You may need a hex key set, a chain whip (if also replacing the chain), and possibly a torque wrench for accurate tightening.

How often should I replace the inner plate?

The lifespan of the inner plate depends on usage and conditions. Inspect it regularly for wear. Replace when shifting performance degrades or if the plate is visibly damaged.

Where can I find the correct torque specifications for the screws?

Check the Shimano technical documentation for your RD-M772 derailleur, or consult a professional bike mechanic.

Is the inner plate compatible with other Shimano derailleurs?

No, this inner plate (MAD01-5W7) is specifically designed for the Shimano RD-M772 SGS model.

What does SGS mean?

SGS stands for "Super Long Cage." It refers to the length of the derailleur cage, which determines the maximum cassette size the derailleur can accommodate.

How do I know if my RD-M772 needs a new inner plate?

If your shifting is sluggish or imprecise, and you see signs of wear on the plate, it's time for a replacement. Also, check for any bending or damage to the plate itself.

Can I use a non-Shimano inner plate?

It is recommended to use genuine Shimano parts for optimal performance and compatibility.

Troubleshooting

Shifting is not smooth or precise after replacement.

Check the derailleur alignment and cable tension. Adjust the barrel adjuster on the shifter or derailleur to fine-tune the shifting. Ensure the derailleur hanger is straight.

Chain is skipping or not engaging properly.

Check the condition of the chain, cassette, and chainrings. Replace worn components as needed. Verify the inner plate is correctly installed and not damaged.

The derailleur is noisy.

Ensure all bolts are tightened to the correct torque. Check for chain rub against the inner plate. Lubricate the derailleur pivot points.
