SRAM Rival AXS 12-Speed Rear Derailleur

Embrace the inevitable: wireless shifting is here, and everything's just fine. The SRAM Rival AXS 12-Speed Rear Derailleur shifts better than anything before it, over and over and over again. Concerns about charging batteries or water ingress are dead-ends, so let them go. These derailleurs are dialed and foolproof, amazing tech that definitely fits into that "don't know how I lived without it" category. If you're missing your cables, you can add them to that old product shrine you made with rotary phones, VCR's, and inner tubes.
