Bring a worn XX1 Eagle rear derailleur back to crisp, quiet shifting with a genuine SRAM service kit. This is the complete cage rebuild package - matched X-SYNC pulley wheels, the alloy inner cage plate and the correct hardware - so you can refresh a tired drivetrain instead of replacing the whole mech, with a grey inner cage finish.

Highlights

  • Genuine SRAM XX1 Eagle 12-speed rear derailleur service part
  • Includes upper and lower X-SYNC pulley wheels plus the inner cage plate
  • Grey inner cage finish
  • Restores smooth, quiet chain tracking on a worn or damaged mech
  • Supplied with titanium pulley bolts and cage hardware

What it does

Pulley wheels and cage plates wear over time, especially in gritty conditions, leading to noise, sloppy shifting and chain slap. Replacing them with the matched X-SYNC set returns the derailleur to factory chain retention and shift feel. The X-SYNC tooth profile uses tall, alternating teeth to grip the Eagle chain securely and resist drops on rough ground.

Inner cage and hardware

The kit pairs the alloy inner cage plate with an upper and lower pulley wheel and the matching titanium pulley bolts, so the assembly goes back together with the correct spacing and tension. Note that the lower pulley is the larger of the two and the pulleys must be fitted in their correct positions.

Compatibility and fit

Designed for SRAM XX1 Eagle 12-speed rear derailleurs. This is a mechanical drivetrain service part. If you are unsure whether this matches your exact derailleur model or generation, contact us before ordering - the cage assembly is specific to the XX1 Eagle platform.
