Sram GX DH 1x X-HORIZON 7S rear derailleur

Sram understand that the gnarly line requires a lot more focus than a lap of the supermarket. That’s why they packed the GX DH 1x X-HORIZON™ rear derailleur with World Championship-winning features, and gave it a price tag that speaks more to the Wednesday Night Championships. This is a DH derailleur that is easier to shift, is incredibly precise and keeps the unwanted noise of chain slap to a minimum, so you can concentrate on the sweet feeling of nailing your line.

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 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.

X-Actuation
Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette.

X-Horizon
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.

X-Sync
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.
