What is the SRAM X-Sync Pulley Assembly?

The SRAM X-Sync Pulley Assembly is a replacement jockey wheel assembly for SRAM rear derailleurs. Pulley wheels wear over time and contribute to drivetrain friction, noise, and reduced shifting precision when they become worn. Replacing with a fresh X-Sync Pulley Assembly restores optimal drivetrain performance. Confirm your specific derailleur model compatibility before ordering.

A cost-effective way to extend the life of a quality SRAM rear derailleur without full replacement. Regular pulley maintenance is a simple part of keeping any mechanical drivetrain running smoothly.
