X01 10-Speed DH X-HORIZON™ Rear Derailleur
ACTION HERO
The 10-speed X-HORIZON™ rear derailleur makes shifting smooth and reliable no matter where you ride. Engineered to maintain consistent chain gap across all ten gears, X-HORIZON™ eliminates vertical movement for faster shifting, reduced shift force and an end to ghost shifting. ROLLER BEARING CLUTCH™ technology and the 12-tooth X-SYNC™ pulley wheels hold the chain in place, reducing bounce and chain slap. And CAGE LOCK™ technology makes wheel removal and installation easier than ever. Paired with the X0 10-speed shifter, X-HORIZON™ forms the backbone of EXACT ACTUATION™ technology—and that means completely smooth shifting action.
- X-HORIZON™ technology provides more responsive shifting and eliminates ghost shifting, a common problem on DH bikes
- Two cage lengths for various applications, including abnormally long chain stay growth
- EXACT ACTUATION™ variant allows upgrades to existing bikes in the aftermarket
- ROLLER BEARING CLUTCH™ with CAGE LOCK™ sets the industry standard

Technology
- CAGE LOCK™
-
With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
- EXACT ACTUATION™
-
When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
- ROLLER BEARING CLUTCH™
-
ROLLER BEARING CLUTCH™ rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With ROLLER BEARING CLUTCH™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.
- 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.
- X-SYNC™
-
SRAM X-SYNC™ 1x chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain.

“When SRAM’s XX1 drivetrain appeared a couple of years ago now, it was nothing short of a revolution, and certainly not just because it goes to 11…lighter, quieter, more reliable, and easier to operate. The obituary of the front derailleur was short and to the point: “so long, and good riddance. It turned out to be everything we had hoped for and then some, simplifying the drivetrain and making shifts count when every millisecond can make a difference.”
