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.

CAGE LOCK ™
The CAGE LOCK ™ technology in the rear derailleur makes rear wheel removal and installation and chain mounting quicker and easier than ever. Simply push the cage forward (to release the chain tension) and lock.

ROLLER BEARING CLUTCH ™
ROLLER BEARING CLUTCH ™ switchgear offers maximum propulsion 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 the SRAM 1 compartment, ensures precise and constant switching along the entire cassette.

X-SYNC ™ 2
X-SYNC ™ 2 EAGLE is the latest evolution of SRAM's X-SYNC ™ technology. The tooth profile of the chainring increases chain tension and efficiency when pedaling. The sprocket life is higher as the X SYNC EAGLE ™ technology reduces friction and contamination.
