Thanks to its “horizontal parallelogram” design, X-HORIZON can keep the chain gap the same across all 11 gears. By taking vertical movement out of the equation, this design doesn’t just make shifting faster—it reduces shift force and eliminates ghost shifting.
ROLLER BEARING CLUTCH technology reduces bounce and chain slap. CAGE LOCK technology makes wheel removal and installation easier than ever before. Paired with the X01 shifter, the X-HORIZON RD forms the backbone of X-ACTUATION™ technology: the key to totally smooth shifting action.
Large upper pulley offset automatically adjusts chain gap
X-HORIZON™ design reduces shift force and ghost shifting
12-tooth X-SYNC™ pulley wheels
TYPE 2 technologies: ROLLING BEARING CLUTCH™ and CAGE LOCK™
Cage Lock™: The first rear derailleur of its kind, SRAM TYPE 2 lets you push your cage forward and lock it into place with the push of a button. This creates slack, removing all tension from the chain. With Cage Lock, TYPE 2 makes wheel removal and installation—as well as chain installation—easier than any other derailleur on earth.
Just push the cage forward—creating slack—and lock it in place.
The chain stays perfectly loose, letting the derailleur swing out of the way. When you’re ready to ride again, simply unlock the cage and go.
Roller Bearing Clutch™: Designed for X0 and X9 families, TYPE 2 rear derailleur delivers maximum drivetrain stability—even through the most punishing technical terrain. With Roller Bearing Clutch™ technology, SRAM TYPE 2 eliminates derailleur bounce and chain slap without sacrificing precision.
A one-way roller clutch controls chain tension for consistent shifting
Self-lubricating for consistently smooth action
360 degree clutch force for reliability and durability
TYPE 2’s clutch force comes factory calibrated by SRAM
Consistent shifting feel
Maintenance free clutch design
X-Actuation™: Developed specifically for SRAM XX1, X-ACTUATION keeps shifting sharp and consistent across the entire 10-42T cassette.
X-Horizon™: This XX1 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 consistent chain gap across all gears.
X-Sync™: A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire XX1 chainring, perfectly mirroring the 1X11 XX1 specific chain’s inner and outer links for maximum control.
