FAQs
What is the diameter of these pulley wheels?
The overall diameter of each pulley wheel is 38mm.
Are these pulley wheels suitable for any Shimano rear derailleur?
No, these are specifically designed for Shimano Tourney 6/7/8 speed rear derailleurs, including models like RD-TY05/15/20/22/30/CT92/MJ05.
What material are the pulley wheels made of?
The pulley wheels themselves are made of durable nylon. The package also includes metal bushings and plates.
How many pulley wheels are included in the set?
The set includes two nylon pulley wheels.
Can I use these on a 9-speed or 10-speed drivetrain?
No, these pulleys are designed for 6, 7, or 8-speed systems and may not function correctly with higher-speed drivetrains.
Do I need any special tools to install these?
Basic bicycle tools such as Allen wrenches are typically required for installation. If you are unsure, consult a local bike shop.
Where are these pulleys typically used (MTB or Road)?
They are suitable for both Mountain bikes (MTB) and Road bikes equipped with compatible Shimano Tourney rear derailleurs.
Troubleshooting
Chain skipping or poor shifting after installation
Ensure the pulley wheels are installed in the correct orientation (check for 'TEETH' markings) and that the derailleur cable tension is properly adjusted. Verify compatibility with your specific derailleur model.
Pulley wheels wobble or feel loose
Confirm that the metal plates and bushings are correctly seated and that the mounting bolts are tightened securely (but do not overtighten, which can damage the derailleur).
Excessive noise during operation
Clean any debris from the pulley teeth and the chain. Ensure the derailleur itself is properly lubricated at its pivot points. Worn chain or cassette can also cause noise.
Pros and Cons
Pros
- Directly compatible with specified Shimano Tourney derailleurs.
- Provides a cost-effective solution for replacing worn pulley wheels.
- Nylon construction offers good durability for regular use.
- Easy installation for users comfortable with basic bicycle maintenance.
Cons
- Not designed for high-performance or competitive cycling.

Setup, Compatibility & Care
Compatibility: Ensure your rear derailleur is one of the following Shimano models: RD-TY05, RD-TY15, RD-TY20, RD-TY22, RD-TY30, RD-CT92, or RD-MJ05. These are typically found on entry-level 6, 7, or 8-speed drivetrains.
Setup:
- Remove the rear wheel from your bicycle.
- Locate the two pulley wheels on your existing rear derailleur.
- Unscrew and remove the old pulley wheels.
- Install the new nylon pulley wheels using the provided metal plates and bushings. Ensure the 'TEETH' indicator on the pulleys (if present) aligns with the chain's direction of travel.
- Reinstall the rear wheel and check shifting.
Care:
- Periodically clean the pulley wheels with a dry cloth or brush to remove dirt and debris that can impede performance.
- Lubricate the derailleur pivot points, not the pulley wheel bearings themselves, as they are typically sealed.
- Inspect for wear regularly. Replace if significant grooving or damage is observed.
