⚙️ What it does
Your rear derailleur has two small wheels:
- ???? Guide pulley (top) → controls shifting accuracy
- ???? Tension pulley (bottom) → maintains chain tension
When these wear out, you get:
- Noisy drivetrain
- Sloppy shifting
- Increased chain wear
???? Replacing them restores smooth performance.
???? Compatibility
This pulley set works with multiple Shimano 10-speed derailleurs, including:
- Shimano 105 RD-5700 series
- Shimano Deore / SLX / XT:
- RD-M662
- RD-M663
- RD-M772
- RD-M773
???? It’s a cross-compatible Shimano design, used across both road and MTB 10-speed systems
