Yes. Just like the proven SRAM RED and Force eTap AXS rear derailleurs, the spring clutch equipped Rival eTap AXS rear derailleur is capable of excellent 1x chain system management when paired with the Rival 1x crankset’s narrow-wide chainring tooth profile.
The Rival eTap AXS rear derailleur will work with AXS 12-speed cassettes from 10-28T up to 10-36T.
Additionally, you can expand your range further with our Rival XPLR eTap AXS rear derailleur, which is compatible with our 10-44T, 11-44T, and 10-36T cassettes.
With a Rival 1x crankset, you can also use an Eagle AXS rear derailleur, Eagle AXS 10-50T or 10-52T cassette with an Eagle 12-speed chain. Such a setup would also be compatible with Rival eTap AXS shift-brake levers.
