Genuine Shimano Dura-Ace jockey wheel set designed for RD-7900/7970 rear derailleurs. Both guide and tension pulleys feature precision sealed bearings that maintain smooth, friction-free drivetrain operation under load. Periodic pulley replacement is essential for preserving crisp shifting response and extending derailleur longevity, as worn wheels compromise indexing accuracy and increase chain wear. These OEM components restore your drivetrain to factory performance standards.
Set comprises of two pulley wheels and is a genuine Shimano replacement part
