Cage Lock – With 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.

Roller Bearing Clutch – This technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuation – Developed specifically for SRAM 1x, X-Actuation keeps shifting sharp and consistent across the entire cassette.

X-Horizon – This 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.

Updated Cage Architecture – Better chain retention and precise shifts.

Backwards Compatible – Works with both 10-50t and new 10-52t SRAM cassettes.
