SRAM GX 1x11 X-HORIZON Rear Derailleur 11-speed - Red

RIDE YOUR WAY.
For every bike, there’s a rider. A rider who builds it. A rider who knows it. A rider who’s always ready to take the bike somewhere new. Introducing GX, the drivetrain for people who love to ride without restraint. From beginner to expert, GX delivers personalized gear choices that take you as far and wide as you want to go. Engineered in Germany with 1x and 2x options, SRAM GX brings the power of riding to everyone, everywhere.



The SRAM GX 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
• Technologies: X-HORIZON™, X-ACTUATION™, X-SYNC™, ROLLER BEARING CLUTCH™, CAGE LOCK™

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.



Developed specifically for SRAM X1, X-ACTUATION keeps shifting sharp and consistent across the entire 10-42T cassette. Multi-adjustable trigger shifter. MatchMaker X compatible.



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.



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.



SRAM X-SYNC™ provides 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.
