X1 X-HORIZON™ Rear Derailleur

SMOOTH AND RELIABLE

Every detail of the 11-speed X1 X-HORIZON™ rear derailleur is engineered for smooth, reliable shifting action—from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, X-HORIZON™ shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCK™ technology, wheel removal and installation are easier than ever.

  • X-HORIZON™ design reduces shift force, ghost shifting and chain slap
  • 12-tooth X-SYNC™ pulley wheels
  • Large upper pulley offset automatically adjusts chain gap
  • Sealed cartridge bearings
  • Aluminum Cage

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-ACTUATION™

Developed specifically for SRAM 1X, X-ACTUATION keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.

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.

SRAM X1 Reviewed | Dirt Rag Magazine

“Whether you’re a cross-country, trail or all-mountain rider, this X1 group is a great way to get a taste of wide-ratio 1x philosophy.”

“The X1 group has fared great and despite the sometimes peanut-butter-like mud I’ve encountered, I haven’t noticed a distinct difference in performance between the two drives.” (XX1 vs. X1)

“The X1 group looks great and performs well. If you are looking to give 1x a try and don’t mind the extra grams, this drivetrain won’t let you down.”

SRAM X1 | long-term test | Enduro Mountainbike Magazine

“After 18 – parts very rainy – races and a lot of tours the drivetrain don’t show any signs of fatigue and still works as the first test ride.”
