• 12-tooth X-Sync chain guide pulley
• The most affordable 1x rear derailleur with a wide range of features
• X-Horizon design reduces shift effort and chain slap
• Long Cage

Cage Lock
Thanks to the rear derailleur’s CAGE LOCK technology, removing and installing the rear wheel and chain is easier and faster than ever. Simply push the cage forward (to release chain tension) and lock it in place.

Roller Bearing Clutch
ROLLER BEARING CLUTCH rear derailleurs provide maximum riding stability, even on very rough terrain. ROLLER BEARING CLUTCH technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuation
X-ACTUATION technology, developed specifically for SRAM 1x, ensures precise and consistent shifting across the entire cassette.

X-Horizon
The parallelogram design of the X-HORIZON rear derailleur limits horizontal movement, eliminating “ghost shifting” and reducing shift effort. For faster and more precise shifting, the wide offset of the upper pulley maintains a consistent chain gap in every gear.

X-Sync
SRAM’s X-SYNC 1x chainrings deliver maximum performance and durability. The long tooth edges of SRAM X-SYNC grip the chain before traditional triangular teeth do. The narrow, sharp tooth profile and rounded, angled edges support chain retention. To provide the best possible performance even in muddy conditions, X-SYNC chainrings feature recesses that remove dirt and mud from the chain’s inner links and rollers. Made in Germany, X-SYNC chainrings are a key component of SRAM’s 1x drivetrain.
