Product Info

The SRAM X01 Eagle 12-Speed Rear Derailleur sits near the top of the pack when it comes to controlling your shifts, a lightweight chain commander that's fully in charge of your metal links, relaying your thumb-orders with speed and precision. It'll work with SRAM's new 52-tooth cassette, as well as being backward-compatible with older Eagle components too.

Product Details


Updated Cage ArchitectureBetter chain retention and precise shifts.

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.

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

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

X-HorizonThis 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.


Backwards CompatibleWorks with both 10-50t and new 10-52t SRAM cassettes.
