I used this for about 500 miles, and decided to go with a 2x force set up. Works perfectly fine, just cosmetic scratches. ****Does not include battery**** The set includes the derailleur and 10-52t GX Eagle cassette and XD Free Hub Body, providing everything you need to upgrade your bike's rear derailleur system.
The GX AXS upgrade kit is your entry into the simplicity of the wireless drivetrain. The upgrade kit is compatible with all SRAM Eagle Ecosystem cassettes and crank arms. AXS BATTERY COVER: A lightweight cover that protects the battery while it is mounted on the rear derailleur.
