SRAM Red E1 AXS 12-speed Rear Derailleur

The Red E1 AXS rear derailleur from SRAM for efficient and smooth shifting

The SRAM Red E1 AXS rear derailleur with electronic control is suitable for 1x and 2x road bike drivetrains with cassettes from 10-28 to 10-36 teeth. Large X-Sync pulleys are dirt-resistant and keep the chain exactly where it belongs, while Orbit chain management, with its rear derailleur damping, promises quiet, smooth shifting even on rough surfaces. Thanks to the AXS connection, your drivetrain can be conveniently connected and personalised via a smartphone app.

Technology:

AXS
AXS is SRAM's electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows you to view battery status, change component behaviour, adjust controls, receive maintenance reminders and update firmware.

eTap
SRAM's eTap is a simple, unambiguous and intuitive shifting logic. With the shift lever on the left-hand side you move the rear derailleur inwards to a larger sprocket, with the shift lever on the right-hand side you move the derailleur outwards to a smaller sprocket. With the shift lever pressed down, you can directly shift several gears. Pressing both shift levers at the same time causes a front derailleur movement in 2x shifting systems.

X-Sync
The X-Sync tooth design is characterised by long, rounded and slanted tooth edges with a narrow profile. Derailleur pulleys with X-Sync technology support the chain guide and remain unaffected by dust and mud.

Orbit
Orbit technology is an innovative form of rear derailleur movement control. It uses silicone fluid as part of an elegant and ultralight damper system. Compared to a conventional friction clutch system, the Orbit technology generates no additional resistance at the rear derailleur spring during slow or light movement. This results in easier shifting and removal of the rear wheel. During the ride, the liquid damper holds the chain back in a sophisticated and elegant way. With the highest reliability and chain tension, for 2x and 1x systems.
