You'll typically need a set of Allen keys and possibly a chain whip or a chain tool depending on the installation process.

Replacement frequency depends on usage and conditions. Inspect the pulleys regularly and replace them if they show signs of wear, damage, or reduced performance.

While aftermarket options exist, using a genuine Shimano pulley set ensures compatibility and optimal performance with your RD-R7000 derailleur.

Inspect the pulleys for debris or damage. Clean the pulleys and chain. If the noise persists, replace the pulley set.
