Bring crisp, precise shifting back to your SRAM XX 10-speed rear derailleur with a genuine factory inner cage assembly in the medium-cage length. Worn pulleys or a damaged cage rob you of shift quality and chain control - this service part restores both without the cost of a whole new derailleur.

Highlights

• Genuine SRAM XX replacement inner cage assembly (medium cage)
• Includes the carbon inner cage, upper and lower pulley wheels and cage tension spring
• Restores accurate Exact Actuation shifting on a tired or crash-damaged derailleur
• Medium cage suits tighter-range, race-oriented gearing
• Lightweight carbon construction in keeping with the XX groupset

What it is

This is the inner cage assembly (service part) for the original SRAM XX 10-speed mountain bike rear derailleur. It carries the chain through the upper and lower pulleys and holds the cage tension spring that keeps your chain taut, so replacing it as a unit returns the derailleur to factory shift performance.

Medium cage

The medium-cage version is matched to tighter-range, race-oriented gearing where a shorter cage keeps the chain crisp and controlled. Match the replacement cage length to the cage length your derailleur was originally built with.

Compatibility and fit

Designed for the original SRAM XX 10-speed rear derailleur using SRAM Exact Actuation (3mm of derailleur movement per shift). It is a service component for that derailleur only - it is not a complete derailleur, and it is not compatible with Eagle, XX1, AXS or T-Type Transmission systems. The outer cage and cage pin are a separate part. If you are unsure which cage length your derailleur uses, check before ordering.
