Setup, Compatibility & Care
Before installation, ensure your derailleur cage is a short-cage model as defined by the X0, X7, and X9 manufacturing years listed. To install, remove the mounting bolts on the derailleur cage, replace the old pulleys with the new set, and re-torque the bolts to the manufacturer's specification. Use a light, dry-film lubricant on the bushings to ensure smooth operation. Avoid degreasers that penetrate deep into the bushing assembly, as these can strip away necessary internal lubrication.
