SRAM RED AXS™ 12-Speed Rear Derailleur

The RED AXS™ rear derailleur is the master component of your AXS™ groupset and the latest version is lighter and more efficient than ever before. Without this interactive piece of engineering art there’s... no way forward!
This is where everything comes together. It is through the rear derailleur that all components of the AXS™ system can communicate with each other. Yet, it is not only responsible for the interaction between the single AXS™ components, but it also communicates with the SRAM AXS™ app and many compatible bike computers via Bluetooth Smart and ANT+.
 
The rear derailleur with a single shift lever length is suitable for all SRAM Road 12-speed cassettes from 10-28 to 10-36 as well as for single and double drive units. And, of course, it comes with a long list of high-end technologies ensuring a quiet and high-performance road bike drivetrain.
 
A particular highlight is the SRAM Orbit™ technology. A rear derailleur movement control mechanism that uses a special silicone fluid as part of the damping system. Compared to standard roller bearing clutch mechanisms, this technology creates no additional resistance at the spring of the rear derailleur. This allows for smoother and faster shifting. Besides, the fluid damper reliably maintains chain tension while riding for maximum chain control even in rough terrain.
