Why We Like The Rival AXS 12-Speed Rear Derailleur

Building off the success and engineering of the Force AXS system, Rival AXS delivers powerful and consistent shifting in a more affordable package. Being envious of the clean-looking aero bikes of today, we’re swapping our mechanical shifting for the full wireless package. The derailleur couldn’t be easier to install. Just 1 bolt and a quick app download and we’re all set to go. The shifting action is always consistent, so no matter how tired or cross-eyed we are we aren’t fumbling around with trying to get just the right amount of actuation.


  • Reliable 12-speed Rival AXS rear derailleur that can handle any surface
  • Intuitive shifting offers precision and an easy setup
