Get a crash-damaged or worn SRAM X0 Eagle Transmission rear derailleur shifting crisply again without replacing the entire unit. This complete cage assembly bolts into your existing derailleur body and restores full T-Type performance.

Highlights

  • Full replacement cage assembly for T-Type Eagle AXS derailleurs
  • Includes outer cage, inner cage, damper and both pulley wheels
  • X0 specification: durable alloy Transmission cage
  • Tool-free cage swap on the rebuildable Transmission platform
  • A fraction of the cost of a complete rear derailleur

What it is

The cage assembly is the moving section of the derailleur that guides and tensions the chain, and it is the part most exposed to rock strikes and crashes. Because SRAM Eagle Transmission is designed to be rebuildable, a damaged cage can simply be unscrewed and replaced rather than scrapping the whole derailleur.

Damper and pulleys included

This kit is the complete assembly: outer and inner cages, the integrated fluid damper that keeps the chain taut over rough terrain, and the upper and lower pulley wheels. It is a one-box fix for a bent cage, a seized damper or worn jockey wheels. The X0 kit includes two T25 aluminium pulley bolts.

Compatibility and fit

Designed for the SRAM X0 Eagle Transmission rear derailleur (RD-X0-E-B1). The cage assembly is mechanically interchangeable across the T-Type Eagle Transmission family (XX SL, XX, X0 and GX), so it can also be used to service or upgrade other Transmission derailleurs. For 12-speed Eagle AXS Transmission (T-Type) drivetrains only; not compatible with earlier Eagle AXS or mechanical Eagle derailleurs.

SRAM warrants this product to be free from defects in materials and workmanship for two years from the original date of purchase, in line with SRAM's standard warranty terms. The warranty does not cover damage caused by crashes, impact, misuse, improper installation or normal wear (including pulley wheel wear).

For any warranty claim or support, please return the item to Tune Cycles and we will assist you with the process.
