Compatibility

SRAM GX Eagle AXS Transmission Upgrade Kit (RD-UPK-GXTE-A1) is a SRAM rear derailleur. It uses Electronic (AXS) shifting. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.
