The rear derailleur of the new Sram Eagle Transmission components has an interface without a derailleur hanger; the thru-axle of the rear wheel and the rear derailleur form a more direct connection. The technology is downwardly compatible in some areas; every frame that has the so-called UDH specification with an interface without a derailleur hanger can be upgraded. (universalderailleurhanger.com). As mentioned, the Eagle Transmission rear derailleur is connected to the axle system and is designed to be extremely robust against lateral and frontal impacts.

The Sram engineers have also paid particular attention to ease of adjustment: The new derailleur does not need an AXS app to start operating. Adjusting the so-called chain gap should also be simplified and the drivetrain should be easy to adjust correctly, especially with rear triangles in the sag. No readjustment is necessary after the rear wheel has been installed and removed. Adjustment screws have even been dispensed with altogether.

The new Eagle Transmission parts are available in three hierarchy levels, the groupsets are called XX SL Eagle Transmission, XX Eagle Transmission and X0 Eagle Transmission. As before, the wireless AXS technology and cassettes with 10-52 sprockets are used. New on board is a new shift lever, the so-called Pod Controller, which has been redesigned in terms of ergonomics. The XX and X0 groupsets are compatible with bash guards and designed for e-mountainbikes. And for fans of power meters, there are also corresponding cranks available.
