Wireless rear derailleur
SRAM RED AXS E1 Rear Derailleur
The flagship 12-speed wireless rear mech from the 2024 RED AXS group, lighter and quicker than before with a carbon cage that handles 1x or 2x set-ups up to a 36T sprocket.
Highlights
Why we rate it
Faster, lighter mechanism
The E1 redesign trims weight over the previous RED and speeds up each shift, so changes under load feel crisper.
Orbit chain management
A fluid damper keeps the chain calm over rough roads without the heavy spring feel of a traditional clutch.
1x or 2x
One derailleur covers 10-28T through 10-36T cassettes whether you run a double or a single ring.
Ceramic pulley bearings
Top-tier bearings and a carbon cage keep drag and weight to a minimum.
AXS app control
Pair it with any AXS shifter and tune shift logic, button mapping and battery alerts from your phone.
