SRAM GX Eagle Transmission Derailleur – RD-GX-E-B1 (12sp AXS)

SRAM's GX Eagle Transmission, landed in The Vault. This is the RD-GX-E-B1 — the wireless AXS T-Type rear derailleur, 12-speed, up to a 52T cassette, 1x.

It's the Transmission party trick: a hangerless Full Mount design that bolts straight to the axle on any UDH frame — no derailleur hanger, dead-simple setup, no limit-screw fiddling. Steel inner cage for durability, plus replaceable skid plates, a two-piece outer link, and a tool-free cage and clutch, making it the most rebuildable derailleur SRAM builds.

Needs a UDH / Transmission-compatible frame. The AXS battery and Pod controller are sold separately.

Condition: Brand New in Box

Included: Derailleur only — no battery or AXS Pod controller.

Local pickup in North Van, or we can ship.
