Product Info

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!

Product Details


Cage LockWith Cage Lock technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into place.

AXS EnabledThis allows easy personalization.

Roller Bearing ClutchThis technology eliminates derailleur bounce and chain slap without sacrificing precision.

Updated Cage ArchitectureBetter chain retention and precise shifts.

X-HORIZON™The X-HORIZON™ rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

12-Tooth X-SYNC™ Pulley Wheels
