Product Information
Full details
The Shimano Tourney Jockey Wheels Pulley Set (RD-A070) is designed for budget-conscious cyclists and commuters who need to restore crisp, reliable shifting to their 7-speed drivetrain. This genuine replacement kit offers a perfect fit for Shimano RD-A070 rear derailleurs, ensuring your chain tracks smoothly and shifts remain consistent. While these pulleys are highly durable, they are specifically engineered for the A070 series and may not be cross-compatible with higher-end or non-Shimano derailleur systems.

FAQs
Are these pulleys compatible with 8-speed systems?
No, this set is specifically designed for the RD-A070 7-speed system.
Do I need special tools to replace these?
You generally only need standard hex keys or screwdrivers to remove the derailleur cage plates.
How do I know which is the guide pulley vs the tension pulley?
The guide pulley is usually marked and has a bit of lateral float, while the tension pulley is often more fixed.
Should I lubricate the new pulleys?
A very light application of bicycle chain lube to the central bearing area is recommended for smooth performance.
Will this kit fix skipping gears?
Worn pulleys are a common cause of skipping, but it may also be due to cable tension or a worn chain/cassette.
Troubleshooting
Derailleur makes a clicking noise after install
Check that the guide and tension pulleys are installed in the correct positions; the guide pulley typically has a small amount of side-to-side play.
Pulley does not spin freely
Ensure the dust covers are seated correctly and that you have not overtightened the mounting bolts.

Setup, Compatibility & Care
To install this pulley set, you will need a flat-head or Phillips screwdriver (depending on your bolt heads) and a 3mm or 4mm Allen key. Ensure the bike is in the smallest cog before starting to reduce cable tension. Simply remove the outer derailleur cage plate, swap the old pulleys for the new ones, and re-secure the plate. Always clean the pivot points of the derailleur cage while the pulleys are off to ensure maximum efficiency. We recommend applying a light drop of bicycle-specific lubricant to the center of the new pulleys to ensure they spin freely without attracting excess grime.
