Overview
SRAM S1000 Eagle Transmission is the OE-only, wireless 12-speed T-Type derailleur that brings Transmission shifting to more affordable e-MTBs and MTBs.
Eagle Transmission is SRAM's T-Type 12-speed 1x system: Full Mount derailleurs bolt directly around the rear axle with no hanger, and cassette mapping plus X-Sync tooth profiles give, per SRAM, the best shift under load – even with the added power of E-MTB. All T-Type components can be mixed and matched.
The S1000 Eagle Transmission derailleur is the wireless entry point to the Transmission ecosystem, sharing the GX Transmission architecture in a black-on-black finish with a new drag spring cage damper. It is available as original equipment on complete bikes only.
