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 cage slap
- 12-tooth X-SYNC™ pulley wheels
- Large upper pulley offset automatically adjusts chain gap
- Sealed cartridge bearings
- Aluminum cage
With CAGE LOCK technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into place.
ROLLER BEARING CLUTCH
ROLLER BEARING CLUTCH technology eliminates derailleur bounce and chain slap without sacrificing precision.
Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette.
This 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.
SRAM X-SYNC 1x chainrings 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 chainrings 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. Accept no imitation.
