SRAM GX Eagle AXS 12-Speed Rear Derailleur

Time keeps on ticking, ticking, ticking. And your SRAM GX Eagle AXS 12-Speed Rear Derailleur keeps on shifting. Perfectly. Over and over again. We used to wind watches and store encyclopedias in our living rooms, now our phones perform a whole office's duties while giving us access to everything known to humanity. Wireless shifting is just one of those things that's undeniably better: instant smooth shifting at the touch of a button, every single time. Beep and borp, bring it on!
