SRAM X-Sync Pulley Assembly is a direct-fit replacement for SRAM rear derailleurs, keeping your drivetrain shifting cleanly and running quietly over time. Designed to work with SRAM's X-Sync tooth profiling, the pulley assembly maintains precise chain engagement through the full range of your cassette. When your current pulleys show wear — a notched or hooked tooth profile is the tell — swapping in a fresh set restores the crispness your derailleur was built to deliver. This is a straightforward, high-confidence service part for riders who prefer to maintain their components rather than replace the full derailleur. Keeping your pulley assembly in good shape reduces drivetrain friction and extends the life of your chain and cassette alongside it.
