technologies:

CAGE LOCK ™:

With CAGE LOCK ™ technology in the rear derailleur, removing and installing the rear wheel and mounting the chain are quicker and easier than ever. Simply push the cage forward (to release the chain tension) and lock.

ROLLER BEARING CLUTCH ™:

The rear derailleur offers maximum drive stability - even on grueling and highly demanding terrain. ROLLER BEARING CLUTCH ™ technology puts an end to wobbly rear derailleurs and beating chains - without sacrificing precision.

X-ACTUATION ™:

The X-ACTUATION ™ technology, specially developed for SRAM 1x ™, ensures precise and constant switching along the entire cassette.

X-HORIZON ™:

The parallelogram design of the X-HORIZON ™ control limits movement along the horizontal axis, eliminating so-called "ghost shifting," while reducing shifting force. For faster and more accurate shifting, the large offset of the upper pulley ensures constant chain spacing in each gear.

X-SYNC ™:

SRAM X-SYNC ™ 1x chainrings provide the highest performance and durability. The long SRAM X-SYNC ™ serrations grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile and the rounded oblique edges support the chain guide. To provide the best possible performance on muddy terrain, the X-SYNC ™ chainrings have recesses to remove debris and mud from the inner links and pulleys. The X-SYNC ™ chainrings manufactured in Germany are an important part of the SRAM 1x ™ drive.
