Overview

The SRAM GX Eagle Transmission AXS Cage Assembly Kit is a full replacement cage for a SRAM GX Eagle Transmission (T-Type) rear derailleur. It includes the outer and inner cages, the damper, and the pulleys, so it rebuilds the moving part of the derailleur after a crash or normal wear. It is the GX-tier, steel-cage service part for a 12-speed Eagle Transmission drivetrain.

Why we love it

We love that this kit brings a crashed or worn GX Transmission derailleur back to life without replacing the whole derailleur.

01It is the full cage assembly: outer and inner cages, the damper, and the pulleys, so it replaces the part that takes the hits.
02It is built for the SRAM GX Eagle Transmission (T-Type) rear derailleur, so the derailleur goes back to a factory setup.
03A bike shop can fit a cage for you.

Why it makes the cut. A cage assembly kit puts a GX Transmission derailleur back into service, and it uses genuine SRAM parts.

Confirm before ordering

This is a service part for the SRAM GX, X0, XX, and XX SL Eagle Transmission (T-Type) rear derailleurs. You can ask your bike mechanic or Hammer & Howl before ordering.

SRAM's Eagle Transmission, also called T-Type, is the direct-mount mountain-bike drivetrain that bolts on without a derailleur hanger. This is a service part for that derailleur, not a chain or a complete derailleur. This GX kit also fits the X0, XX, and XX SL Eagle Transmission derailleurs. To move to a carbon cage, see the SRAM Carbon Eagle Transmission AXS Cage Kit. That kit fits the GX, X0, XX, and XX SL derailleurs and reuses the damper already on yours.

Questions

Which derailleur does it fit?

The SRAM GX Eagle Transmission (T-Type) rear derailleur, model RD-GX-E-B1. This kit also fits the X0, XX, and XX SL Eagle Transmission derailleurs.

Can I upgrade to a carbon cage or the Magic Wheel?

Yes. The SRAM Carbon Eagle Transmission AXS Cage Kit is a carbon cage that fits the GX, X0, XX, and XX SL derailleurs, and it reuses the damper already on yours. For the Magic Wheel lower pulley, see the SRAM XX Eagle Transmission AXS Magic Pulley Kit.

Does it come with pulleys?
