Pair of rolling derailleur rollers P2R

The rear derailleur pulleys play an essential role in the bike's transmission.
There are two rear derailleur pulleys, which ensure the tension and guidance of the chain during gear changes.
The upper pulley is called the "puley" and ensures the movement of the chain, while the lower pulley, called the "string", is responsible for the tension of the chain.
For the precision and smoothness of the sprocket changes, the rear derailleur pulleys must therefore be in perfect condition
