The updated SRAM X01 rear derailleur is nearly identical in function, weight, and performance to the original, with SRAM making some small improvements to the derailleurs clutch mechanism and bearings to improve overall performance and longevity. 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, while Cage Lock technology makes wheel removal and installation easier than ever before. Paired with the X01 shifter, the X-Horizon rear derailleur forms the backbone of X-Actuation technology: the key to totally smooth shifting action.
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 everLarge upper pulley offset automatically adjusts chain gap,X-HORIZON™ design reduces shift force, ghost shifting and chain slap,12-tooth X-SYNC™ pulley wheels,Aluminum Cage,Sealed cartridge bearings.
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. 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. Roller Bearing Clutch Features Roller Bearing Clutch (RBC) rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With RBC 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.
The SRAM X1 rear derailleur shares all of the same great technology as the more expensive X01 model but instead features an aluminium cage instead of carbon which adds a few more grams but also keeps the price down!
